Throughout this manual, information that is presented by the router and entered into the router will be shown in a bordered box, as shown here.

Screen information being displayed or entered.

Initial Router & Management Console Power-Up

The following screen information will be seen on the console connected to the router when it is first powered on:

Terminals supported:

teletype ansi, avt, ibm3101, qvt109, qvt102, qvt119, tvi925, tvi950, vt52,vt100, wyse-50, wyse-vp

Enter terminal type:

As the terminal type is not yet defined at the very first power-up, this screen may be slightly mixed up. Enter at least one <RETURN> (up to three if necessary) on the Network Console in order for the router to determine the baud rate of the terminal used for the console (i.e. auto-baud) and then proceed.

Select your terminal if listed and enter its name in lower case at the prompt, or choose the terminal type teletype if your terminal is not listed. The teletype terminal type operates in scroll mode and may be used successfully until a custom terminal definition is created.

Menu Command Entry

Once the terminal type is specified, the MAIN (LOGIN) MENU will be displayed.

The router uses a “hotkey “ Menu. A menu option is chosen by selection of the desired option number. Entry of parameters is from the “>“ prompt. When a parameter is required, enter the necessary string and end it with a

<Return>. If the entry is not accepted, an error message will be reported and the parameter will have to be re-entered. Should you make an error, the <BACKSPACE> key (for most terminals) deletes the most recently entered characters.

The TELNET SET_UP MENU allows telnet connections to be made to other routers in the network. 1 - Telnet Access

The Telnet Access option allows LAN/WAN network devices to make Telnet connections to this router for management. Once the connection is established, the network device will be presented with the menu interface for configuration management and statistics viewing.

Default: [enabled] Considerations:

When a Telnet connection is made to a router, ensure that the Telnet session is in character mode, and carriage return padding (or translation) is set to NULL (or no translation). The extra character sent when carriage return padding is on will cause some displays to behave erratically.

Note: A Telnet connection from another IP address is allowed three attempts to login with the correct password. After

three failures, that IP address will be rejected for the following ten minutes if any further attempts are made and the following alarm message is logged and displayed on the console:

Alarm: Possible intruder 192.168.89.65 exceeded password attempts limit

Page 18

Menus Reference Manual: Telnet Access Menu

2 - Telnet

Choosing the Telnet option, and specifying the name or IP address of the router you wish to connect to, connects to the other router for configuration purposes and viewing of statistics.

The Device name at the top left of each Menu identifies the router being controlled.

If there is no data transmitted or received for a period of 5 minutes, the Telnet session will be disconnected. This time limit cannot be modified.

To disconnect from the router being controlled, enter Control-C ( ^C ).

Considerations:

If the Internet Address of a remotely connected router is changed, immediately disconnect from the remote router by entering a Control-C ( ^C ) and re-establish a new Telnet connection using the new Internet Address of the remote router.

3 - Telnet Port

The Telnet port option allows you to choose an alternate port number that a remote device can use for Telnet access to this router. This is necessary when Telnet is one of the exported services offered under Network Address Translation (NAT), as the well known port number will be used for the network Telnet server. An alternate port number must be supplied to Telnet to this router.

4 - Show Names

LOAD FLASH SET-UP MENU

Option Description

1. Console (ZMODEM) - Load through serial port

2. Network (TFTP) - Load through IP network

Enter option number, "=" - main menu, <TAB> - previous menu

From the LOAD FLASH SET-UP MENU, the software in the router may be updated to the latest version. The download file, referred to in this section as “###.all”, will be found in the directory with the new software release number ### (e.g. 52V.06.02.01).

Considerations:

When installing a new version of operating software in a router, ensure that the current configuration is backed up before the installation process is started (see Access Setup Menu: Dump and Restore options).

Note: this operation cannot be performed from a secondary IP address.

Page 21

Menus Reference Manual: Load FLASH Set-Up Menu

1 - Console (ZMODEM)

Resets the router and places it in Console load mode. Once the router is in Console load mode, the “###.all” file may be sent using the ZMODEM transfer protocol. The Console load mode may only be used with a direct connection to the serial management port of the router.

The ZMODEM application must be in 32 bit CRC mode for software upgrade transfers. This option must be confirmed before operation by typing “yes” when prompted.

Procedures for performing a Console ZMODEM Flash Load to upgrade the operating software of the router:

1) Save the current configuration of the router (Main menu: option 6).

2) Execute the Console (ZMODEM) command from the Load FLASH Set-Up menu. Confirmation is required. Enter “yes” to proceed.

3) After the router restarts, the router will be in receive ZMODEM mode. The router will display the following

messages on the console port.

System startup Receiving ZMODEM ... **B0100000023be50

4) Start the ZMODEM transfer and send the file “###.all” from the the Operational/Boot Code directory on

the CD-ROM.

5) Once the ZMODEM transfer is complete, the router will verify the file “###.all” in memory, program and verify

the FLASH, clear the configuration to default values (except the password), and then reset. After the reset, the router will operate normally using the newly upgraded software. A byte status message will be displayed on the console port during the programming of the FLASH.

On the rare occasion that during the programming of the FLASH something happens to the bridge/router (power hit or hardware reset), causing the FLASH to become corrupted, the bridge/router will restart in ZMODEM receive mode only. If the bridge/router does not start in ZMODEM receive mode: power down the bridge/router, open the case, locate jumper W4 on the main circuit board (it is next to the batteries), put the jumper across pins 1-2, power up the bridge/router. The bridge/router should now restart and be in ZMODEM receive mode. Once the file transfer is complete, the router will again come up in ZMODEM receive mode. Power down the unit and return the W4 jumper to pin positions 2-3. Please refer to the Servicing Information section of the Installation & Applications Guide for information on removing the case and changing the strap settings.

The ZMODEM Load Flash operation may be aborted (by aborting the ZMODEM transfer and then entering 5 control-X characters “^X” from the console keyboard. After the control-X characters are sent, the router will display a limited menu system. Choose the Abort Load option from the Load FLASH Set-Up menu. This will cause the router to reset and return to normal operations operating from the existing software.

If the ZMODEM transfer operation needs to be restarted after it has been canceled or after loading the first file, simply choose the Console (ZMODEM) option from the Load FLASH Set-Up menu once again.

Considerations:

When the router is placed in Console load BOOT mode, the LAN and WAN interfaces will be disabled. The router will only accept information from the console management port.

The BOOT code of the P1700 may be upgraded by performing a load of the “###.all” file from the the Operational/Boot Code directory on the CD-ROM.

Maximum connection speed for ZMODEM transfer on a P1700 is 38400 Bps.

Page 22

Menus Reference Manual: Load FLASH Set-Up Menu

2 - Network (TFTP)

Resets the router and places it in Network Load mode. Once the router is in Network Load mode, a TFTP connection may be made to the router to upgrade to a new version of software. Make sure to disconnect any telnet sessions to the router before starting the TFTP transfer

The TFTP application must be in “octet” or “binary” mode for software upgrade transfers.

Procedures for performing a Flash Load to upgrade the operating software of the router:

1) Execute the Network (TFTP) command from the Load FLASH Set-Up menu.

2) Enter “none” to connect locally or enter the remote site ID number or alias to connect to a remote site. Login

when connected.

3) Start the TFTP application to be used for transfers to the router. (The IP address of the router may be found in the Internet Set-Up menu.).

4) Put the file “###.all” to the router from the the Operational/Boot Code directory on the CD-ROM. (Any router not in Network Load BOOT mode will respond with an access violation error.)

5) The router will verify the file “###.all” in memory, program and verify the FLASH, clear the configuration

to default values (except: IP Address, IP Routing state, IP Forwarding state, WAN Environment, Link 1 & 2 State, the Switch Type, Directory Numbers, SPIDs, Password and connection data for the remote site, if applicable), and then reset. After the reset, the router will operate normally using the newly upgraded software. In some upgrade situations the Directory Numbers and SPIDs may be corrupted after the upgrade and will need to be re-entered.

- The router may take up to two (2) minutes to program and verify the FLASH. The console will not respond during this time.

To check on the router’s current state during this process, get the file “status.txt” from the router. This file will report the router’s state: both the mode and version if no errors have occurred, or an error message.

Page 23

Menus Reference Manual: Load FLASH Set-Up Menu

PC used for

TFTP transfers

The TFTP Load Flash operation may be aborted by re-connecting to the console of the router and choosing the Abort Load option from the Load FLASH Set-Up menu. This will cause the router to reset and return to normal operations operating from the existing software.

Considerations:

When the router is placed in Network (TFTP) load mode, the router will restart and then remain idle.

In the following diagram of a cluster of routers, when upgrading the three routers in the diagram, the upgrade order should be Router C, then Router B, and finally Router A.

A TFTP software load to router Router C would be performed as follows:

- Using TFTP, get config.txt from each router and save.

- Telnet to Router C. Enter the ID or alias of Router B in the Network (TFTP) option to put Router C in

Network Load mode. When Router C restarts in Network Load mode, the connection to “Router B” will be re-established only if autocall is enabled on router B.

- The TFTP transfer of the upgrade code may now be performed from the PC to Router C. Once

Router C has completed programming the flash and has restarted in operational mode, the connection to Router B will be re-established only if autocall is enabled on router B.

Once router C is operating with the new software, the PC may be used to reload the config.txt file back to Router C.

Repeat for Router B, then again for Router A. Perform the Router B upgrade using the ID or alias of Router A. Router A upgrades would not require a remote site ID as the PC used for TFTP transfers is located on the same LAN as Router A.

CONSOLE MENU

Option Description

1. Dump - Back-up configuration from console

2. Restore - Load configuration from console

Enter option number, “=“ - main menu, <TAB> - previous menu

The options in the Console Menu allow the current configuration settings of this router to be dumped to a backup device or for a saved configuration to be uploaded to restore the router to a previous configuration.

Note: Dump and Restore may not be performed over a telnet connection. 1 - Dump

Lists the configuration changes from the default settings to the console so it may be stored on a PC running a terminalemulation package. It is recommended that after configuration of the bridge/router, the configuration changes be saved so that the device may be restored to these settings if required..

The Dump option should not be used during a connection to another bridge/router.

Note that only changes from the default settings are saved, not the entire configuration.

Two kinds of settings are not considered to be part of the configuration, and therefore are not included in the dump: trace settings and the password.

Procedures for performing a Configuration Dump:

1) Prepare the emulation package so that it is ready to accept the transfer of the configuration file.

2) Send the file (dump) to the PC disk using the Dump command.

3) Use a text editor to check the configuration file saved to the PC disk to confirm that information is still in order. If minor errors occurred, they may be corrected with the text editor. If errors were major, check the emulation package settings and dump the configuration again.

Page 25

Menus Reference Manual: Console Menu

2 - Restore

Restores a configuration to the bridge/router that was previously saved to a disk file with the Dump command.

Note that the Restore will only restore those configuration settings that were changed from the default settings at the time the Dump was performed; Restore does not overwrite the entire configuration. Any changes made since the Dump was performed will not be overwritten and will thus remain in effect after the restore. It is strongly recommended that you do a full reset (under the Diagnostics menu) before performing a Restore to be certain that the system is restored to the state it was in at the time of the Dump. After a full reset, the IP address of the router must be re-entered.

Considerations:

The terminal-emulation package selected should have the capability to pace the loading of commands into the bridge/router. This may be done through the setting of a delay timer (character or line pacing) or a wait for the echo of the character before transmitting the next character.

The pacing function is commonly available, although pacing procedures will vary with each emulation package.

The Load option should not be used during a connection to another bridge/router.

Procedures for performing a Configuration Load:

1) Prepare the PC to transfer the configuration file.

2) Execute the Load command. Confirmation is required. Enter “yes” to proceed.

3) Send the file from the PC to the router.

4) When the transfer is complete, the configuration will have been restored to the bridge/router.

1. State [enabled] - Enable/disable port

2. Path cost [100] - Define network cost for port

3. Priority [128] - Set port priority

Enter option number, “=“ - main menu, <TAB> - previous menu

The LAN Bridge-STP MENU allows the management of the LAN bridging state, path cost, and priority.

1 - State

The State option toggles between Enabling and Disabling of the Spanning Tree Protocol for the LAN port.

Considerations:

When the port is [enabled] the states are reported as either Listen(ing), Learn(ing), Forward(ing) or Block(ing). If the port is disconnected, “Disabled” is shown in the Show Ports display (even if the state is enabled).

When the port is [disabled], it does not participate in frame relay or the learning process. Also, when [disabled] the port is not included in the STP topology calculations and will not be activated by the STP should it be needed to take over from a failed bridge.

Page 28

Menus Reference Manual: LAN Bridge-STP Set-Up Menu

2 - Path Cost

The Path Cost option allows the setting of the contributing path cost to the Root for this port.

Contribution of Path Cost to Root Path Cost:

The path cost to the Root Bridge is added to those path costs of other bridges along the same stream to the Root Bridge. The result is the Root Path Cost.

Once the Root Bridge is selected, a determination of which bridge(s) will become blocked where necessary is made. This determination is made by comparing the sum of the path costs (i.e. the Root Path Cost) to the Root Bridge. Where redundant paths exist, the bridge with the lowest Root Path Cost to the Root Bridge will become the Designated Bridge for the LAN. If all contending bridges’ ports have the same Root Path Costs, then first their Bridge IDs (Priority/MAC address) and second their Port IDs (Port Priority) will be used as tiebreakers.

Default: [100] Range: 1 to 65535

Considerations:

Increasing this value increases the total cost of the path to the Root Bridge. This may (depending on the topology) cause a bridge along the path to the Root bridge to be taken out of service and a blocked bridge to come into service.

Decreasing the value may have the opposite effect.

3 - Priority

The Priority option allows the setting of the port priority. This value is entered in decimal format and appears in hex format in the Port ID/Designated Port identifier (as applicable) of the Port Status display.

Default: [128] (decimal) Range: 0 - 255

Considerations:

Increasing this value lowers the probability of this port becoming the Root port to the Root bridge. Decreasing this value increases the probability.

5. RIP mode [both] - Define RIP send/receive mode

6. Route cost [0] - Cost added to learned routes

Enter option number, “=“ - main menu, <TAB> - previous menu

The LAN IP SET-UP MENU contains options used to enable the router to be recognized as an Internet Protocol device on the network, to negotiate IP routes and to route IP data packets on the LAN.

1 – Secondary IP Set-Up

The Secondary IP Set-up option takes you to the Secondary IP set-up Menu, where this router may be configured to use secondary IP addresses on the local network for local routing.

2 – LAN – NAT Set-Up

The LAN-NAT set-up option takes you to the LAN-NAT set-up Menu, where Network Address Translation parameters for the primary LAN may be assigned. This option would be used when NAT is to be used between the primary LAN and the secondary LAN(s).

3 – IP Address

The IP Address option defines an Internet Protocol (IP) address and corresponding subnet size for the router. The router requires an IP address.

The router supports SNMP that uses UDP for message transmission, and UDP runs on top of IP. An IP address is also required to connect to other routers across the LAN by using Telnet (for example, from a remote router to a local bridge).

The IP address consists of 4 octets and is represented by 4 fields separated by periods (“.”), where each field is specified by a decimal number (e.g. 92.3.1.10). Each decimal number must be less than or equal to 255, that is the maximum value of each 8-bit field.

The size of subnet mask variable defines the number of bits in an IP address to be used for network and subnetwork addressing (the remainder being used for host addressing). Subnetting allows multiple logical networks within a single standard IP network address.

Note: after changing the IP address of this device, a soft reset must be performed to bring the change into effect. Default: [none]

Page 30

Menus Reference Manual: LAN IP Set-Up Menu

Enter :

none, internet address (up to 15 characters)

> Enter :

size of subnet mask (from 8 to 32)

4 - Routing Protocol

The Routing Protocol option defines the type of IP routing protocol to be used on this Local Area Network. The P1700 may be set up to use different types of IP routing protocols on each of its LANs (primary and secondary) and WAN links.

When the routing protocol is defined as none, the P1700 will operate as an IP router but will NOT participate in the exchange of RIP messages between the other IP routers in the network. All IP routing is accomplished by using the static routes table. All routes within the network must be manually entered in the static routing table.

When the routing protocol is defined as rip1, the P1700 will operate as a RIP1 IP router. All routing information will be sent and received via broadcast RIP packets.

When the routing protocol is defined as rip1_compatible, the P1700 will operate as a RIP2 IP router in broadcast mode. All routing information will be sent via broadcast RIP2 packets. Routing information may be received as broadcast RIP1, broadcast RIP2, or multicast RIP2.

When the routing protocol is defined as rip2, the P1700 will operate as a RIP2 IP router. All routing information will be sent via multicast RIP2 packets. Routing information may be received as broadcast RIP2 or multicast RIP2.

Partner routers connected on the network do not need to have their IP routing protocols set to the same values. An IP router at a central site may have it’s routing protocol set to RIP so that it may continue to listen to RIP messages and adapt to the changes of the local network, while the remote locations, with their default routes back to the main router, cannot propagate any incorrect routing information that might be present on the remote segments. Each of the routers at the remote sites would have their routing protocol set to none.

Default: [rip1_compatible] Choices: none, rip1, rip1_compatible, rip2

5 - RIP Mode

The RIP Mode option defines how this P1700 will participate in RIP IP routing message exchange for this subnet.

When the RIP mode is set to both, the P1700 will send and receive RIP routing messages. When the RIP mode is set to send_only, the P1700 will only send RIP routing messages. When the RIP mode is set to receive_only, the P1700 will only receive RIP routing messages.

Default: [both]

Choices: both, send_only, receive_only

Page 31

Menus Reference Manual: LAN IP Set-Up Menu

6 - Route Cost

The Route Cost option defines the amount of extra routing cost to add to routes that are learned from this LAN. This added cost may be useful in forcing learned routes to have a higher cost when they are across a slower LAN connection.

Default: [0]

The Edit Secondary Entry Menu provides options for entering parameters for routing to secondary networks or subnetworks through this router.

When an ID number for a secondary network is entered for the first time, you will be prompted to enter the defining IP address and mask size for the network. Once the secondary network is defined, the IP address and mask cannot be edited with this menu; the entry must be removed and re-entered to change these parameters.

1 - Secondary IP

The Secondary IP Address for this router on the secondary network or subnet with the new ID number is entered here the first time the ID number for this secondary network is entered.

The secondary IP address is used to access the secondary subnet or network through this router.

The IP address consists of 4 eight-bit fields separated by periods (“.”), where each field is specified by a decimal number (e.g. 92.3.1.10). Each decimal number must be less than or equal to 255 (the maximum value of an 8-bit binary number).

* Display only. This address is set when the entry is defined for the first time and may not be changed here; to make a

change, the entry must be removed from the secondary address table and re-entered.

2 - Mask Size

The Mask Size defines the number of contiguous bit locations from the start of the IP address to be used for the subnet mask for this secondary network. The Subnet Mask when applied to the secondary IP address defines this Secondary IP subnet or network.

* Display only. This number is set when the entry is defined for the first time and may not be changed here; to make a

change, the entry must be removed from the secondary address table and re-entered.

Page 34

Menus Reference Manual: Edit Secondary Entry Menu

3 - Subnet Mask

The Subnet Mask option displays the subnet mask defined by the subnet mask size in option 2.

* Display only. This mask is set when the mask size entry is defined for the first time and may not be changed here; to

make a change, the entry must be removed from the secondary address table and re-entered.

4 - Routing Protocol

The Routing Protocol option defines the type of IP routing protocol to be used on this secondary network.

When the routing protocol is defined as none, the P1700 will NOT participate in the exchange of RIP messages for this secondary network with the other networks. Routing on this secondary network is accomplished by using static routes. All routes within this secondary network must be manually entered as the static routes. Host devices and other routers on this network must be statically configured (they will not receive RIP messages). Routes with next hops on this network must be statically configured on this router. In addition to the static routes entered, this router will use routing information learned from other interfaces and networks

When the routing protocol is defined as rip1, the P1700 will use RIP1 IP protocol for this secondary network. All routing information will be sent and received via broadcast RIP packets.

When the routing protocol is defined as rip1_compatible, the P1700 will use RIP2 IP protocol in broadcast mode for this secondary network. All routing information will be sent via broadcast RIP2 packets. Routing information may be received as broadcast RIP1, broadcast RIP2, or multicast RIP2.

When the routing protocol is defined as rip2, the P1700 will use RIP2 IP protocol for this secondary network. All routing information will be sent via multicast RIP2 packets. Routing information may be received as broadcast RIP2 or multicast RIP2.

Networks on this router do not need to use the same IP routing protocols. For example, one secondary network may be set as RIP_compatible to learn and advertise changes to the network, while another may be set to none and must use static routes.

Default: [rip1_compatible] Choices: none, rip1, rip1_compatible, rip2

5 - RIP Mode

The RIP Mode option defines how this P1700 will participate in RIP IP routing message exchange for this subnet.

When the RIP mode is set to both, the P1700 will send and receive RIP routing messages.

When the RIP mode is set to send_only, the P1700 will only send RIP routing messages.

When the RIP mode is set to receive_only, the P1700 will only receive RIP routing messages.

Default: [both] Choices: both, send_only, receive_only

Page 35

Menus Reference Manual: Edit Secondary Entry Menu

6 - Private Route

Setting this secondary network IP address to be a private route causes the IP address and network to not be advertised in the RIP information.

Default: [disabled]

7 - Route Cost

The Route Cost option defines the amount of extra routing cost (in hops) to add to routes that are learned from this Secondary network. This can be used in the case of multiple routes to artificially increase the cost of a less preferred route so that it will be used only if the preferred route is not available. The cost will not be added (and thus not appear in the route statistics) until a connection is made.

Default: [0]

4. Add static entry - Specify IP-IP mapping

5. Remove static entry - Remove static IP mapping

6. NAT enabled [disabled] - Enable address translation

Enter option number, “=“ - main menu, <TAB> - previous menu

The LAN - NAT Menu sets parameters for the NAT address pool for the primary LAN. Network Address Translation (NAT) is a technique that translates private IP addresses on a private network to valid global IP addresses for access to another network. Network Address Port Translation (NAPT) translates both the IP address and the port. The advantage of port translation is that more than one private IP address can be translated to the same single global IP address. NAPT allows data exchanges initiated from hosts with private IP addresses to be sent to other networks via the P1700 using a single global IP address. Port translation can also be used from one private network to another private network if the two networks have conflicting IP addresses.

1 - Translation Type

This option sets the address translation method to be used for NAT. The address may be translated as either a port or an internal IP address. With IP address translation, each internal IP address is mapped to one global IP address; with port translation, several internal IP addresses may be mapped to a single global IP address.

Default: [port]

2 - Dynamic IP Pool

The Dynamic IP Address Pool option defines the block of global IP addresses that may be used to map to internal addresses. The router will assign a global IP address from this pool to the internal address of a device on the network.

The first address in the range must be specified followed by the number of addresses in the pool.

Page 37

Menus Reference Manual: LAN – NAT Menu

3 - Show Address Pool

This option displays the IP address pool for this remote site.

NAT ADDRESS POOL

Pool Address Type Actual Address Status

-------------- ----- --------------- ---------

12.34.5.6 Static 196.23.45.6 In use

12.34.5.12 Static 196.23.45.24 Reserved

23.45.6.10 Dynamic 123.45.67.8 In use

23.45.6.11 Dynamic None assigned Available

23.45.6.12 Dynamic None assigned Available

23.45.6.13 Dynamic None assigned Available

The Pool Address is the internal address to be used on this network, the Actual Address is the global IP address to which the internal address is assigned.

When the last dynamically assigned address in the address pool is reached, the router will automatically use port translation with that address in order to allow as many connections as possible. If there are zero or one address specified for the pool, then port translation will be used for all connections. If zero, the address assigned by the remote router IPCP or the address specified in the “Peer IP address” option will be used. If one address is specified, that address will be used.

4 - Add Static Entry

The Add Static Address option assigns a specific internal IP address of a device to a specific global IP address. When this option is selected, first enter the internal IP address to be assigned then the global IP address.

5 - Remove Static Address

The Remove Static Address option removes the static address assignment from the address pool. Addresses may be removed individually by entering the global IP address to be taken off, or the entire list of static address assignments may be cleared by entering “all”.

6 - NAT Enabled

The NAT enable option enables or disables Network Address Translation on the LAN.

When NAT is enabled this router will not send RIP messages out. The router will be able to receive RIP requests. IP pattern filters and Firewall use the non-translated IP address. (i.e. the private IP address that is used on the private network).

Default: [disabled]

The WAN SET-UP MENU allows the definition of link operation for the router.

1 - Switch Type

Choosing the Switch Type option defines the ISDN switch (signaling) type that this router is connected to. When the Switch Type is changed, a Soft Reset must be performed for this to take effect. This allows the router to

initiate operation with the new switch type. Default: If S/T module is installed: [NET3]

If U module is installed: [NI-1]

Choices: DMS-100, NI-1, NI-2, 5ESS-PP, 5ESS-MP, NET3, TPH1962, KDD, SWEDEN, and NTT

Considerations:

The 5ESS switch types are split into two versions: 5ESS-PP (point to point) and 5ESS-MP (multipoint). In ISDN, point to point means that both B channel links in an ISDN BRI are used for a connection between two devices. Multipoint means that one link of the BRI may be used to connect to one device, the other link may be used to connect to a different device.

Note: this menu item appears only if at least one ISDN module is installed in this router.

4. Show groups

Enter:

The GROUP SETUP MENU provides for grouping sets of ISDN B-channels together. These sets may be hunt groups or callback groups.

A hunt group phone number is defined by the ISDN service provider. This method of grouping the B-channels allows one ISDN phone number to be used to establish connections from remote site devices to multiple B-channels on the central site device. A group of single link protocol remote site devices may all dial in to the same ISDN phone number at the central site and contend for a link connection. This greatly simplifies the configuration process.

By default, all B-channel links are initially configured to be in group 1. Group 1 is defined with multilink operation disabled.

Consideration: If this P1700 is configured with remote site callback enabled, (this router will place a return call when it receives a prompting call from a remote site), then a callback group should be set up. A callback group is a grouping of one (the primary ISDN call number) or two (primary and alternate) ISDN numbers that a remote site router may dial to trigger the callback from this P1700. If a callback group is not set up, the callback would come from the first available ISDN link; if this was not be the primary or alternate number used by the remote site router, the callback would be rejected by the remote site . Note: this option appears only if the router has at least one ISDN U BRI or at least two ISDN S/T BRI modules installed and the Logical ISDN Type is set to ISDN.

Page 43

Menus Reference Manual: Group Set-Up Menu

1 - Force 56K

This option forces the B-channels in this group to use V.110 rate adaptation for all incoming and outgoing calls.

If the path to a destination number passes through a 56 Kbps digital circuit or the destination itself is a 56 K switched digital service, V.110 rate adaptation must be performed to allow the data to be sent at 56 K on the 64 K ISDN lines. When an ISDN call is placed, the local ISDN service must be informed that V.110 rate adaptation is required to fully complete this connection. Adding a percent symbol “%” before the ISDN number will cause the P1700 to send a message to the local ISDN service requesting V.110 rate adaptation.

Note: The link must be disconnected for this operation to take effect. Default: [disabled]

2 - Hunt Group #

Enter the Hunt Group ISDN phone number assigned to this group of B-channels by the ISDN circuit provider. This Hunt Group number is used by this P1700 to inform the remote site partner devices which ISDN number to call when performing a “suspend” or “resume” of a connection managed circuit. This means that the remote site device will call the Hunt Group number when attempting to re-establish the ISDN call.

Note: Hunt Groups are a service from ISDN service providers and must be requested from them. If you have not subscribed for Hunt Group service, select “none” as the entry for this option. If a Hunt Group number is not defined, the ISDN number of the B-channel used to establish the call will be used for connection management negotiations.

When adding entries to the Stored Number table on remote partner ISDN routers, this Hunt Group Number should be entered in the ISDN Number section in the table on the remote router .

Default: [none]

Enter :

none, Directory number (up to 35 characters)

3 - Add Link

Use this option to add a B-channel link to this group. Each link must always belong to only one group, so adding a link to a group will remove it from the previous group.

Link Set-Up Menu – ISDN BRI

If the link has an ISDN BRI interface module and the logical ISDN type is ISDN, the menu will be:

LINK SET-UP 1 MENU

Option Value Description

1. Physical link type *"BRI"

2. Link operation [enabled] - Enable/disable link

3. Logical ISDN type [ISDN]

4. ISDN set-up menu - Configure ISDN operation

5. Group [1]

Enter option number, “=“ - main menu, <TAB> - previous menu

The LINK SET-UP MENU allows the configuration the link connections on this router . The options displayed for this menu will vary depending on what interface modules are installed on this router.

1 - Physical link type

The Physical Link Type option displays the type of interface module installed for this link. This is a display-only item and may not be changed.

Values: BRI

2 - Link Operation

The Link Operation option toggles between [enabled] and [disabled] to allow this link to be used for connections.

Default: [enabled]

3 - Logical ISDN Type (if BRI module installed on this link)

The Logical ISDN Type option allows you to select between a switched (dial up) ISDN circuit or a digital leased circuit to configure the router to match the type of service connected to this interface module.

The ISDN option is used when a switched (dial up) ISDN service is connected to the BRI module.

The Digital_Leased option is used when a permanent leased ISDN circuit is available from your ISDN service provider and is connected to the BRI module; please see the Link Set-up menu on following pages for a description of this option.

When this link is set to use digital leased circuits instead of switching circuits, the ISDN call establishing functions are not displayed on the menu.

Default: [ISDN]

Values: ISDN, Digital_Leased

Page 47

Menus Reference Manual: Link Set-Up Menu

Considerations:

The state of the Logical ISDN type option is saved when performing a software upgrade. This means that when the P1700 restarts, it will return to the operation state that was enabled before the upgrade was performed.

4 - ISDN Set-Up

The ISDN Set-Up option takes you to the ISDN Set-up menu where ISDN switch types and other ISDN parameters may be set.

Note: this option appears only if the router has an ISDN BRI module installed on this link and Logical ISDN Type is set to ISDN.

5 - Group

The identifying number of the Group to which this link is to belong is set here.

Default: [1] Choices: 1 or 2 if a single interface module is present

1 to 4 if two ISDN interfaces present

Consideration for units with two ISDN interface modules:

If this configuration is setup with remote site callback eanbled, (this router will place a return call when it receives a prompting call from a remote site) then a callback group should be set up. A callback group is a grouping of one (the primary ISDN call number) or two (primary and alternate) ISDN numbers that a remote site router may dial to trigger the callback from this router. If a callback group is not set up, the callback would come from the first available ISDN link; this may not be the primary or alternate number used by the remote site router, causing the callback to be rejected by the remote site.

Note: Groups may also be set under the Group Set-up Menu. Links set in that menu need not be set here. Note: this option appears only if the router has at least one ISDN dual BRI module installed on this link and Logical

ISDN type is set to ISDN.

Menus Reference Manual: Link Set-Up Menu

Link Set-Up Menu – Digital Leased

If the link has an ISDN BRI interface module and the logical ISDN type is Digital_Leased, the menu will be:

LINK SET-UP 1 MENU

Option Value Description

1. Physical link type *"BRI"

2. Link operation [enabled] - Enable/disable link

3. Logical ISDN type [Digital_Leased]

4. Frame Relay [enabled] - Enable/disable frame relay

5. Frame relay set-up menu - Configure Frame relay

6. Phantom power detect [disabled] - Detect phantom power

7. Link B channel *[B1] - Assign B channel

Enter option number, “=“ - main menu, <TAB> - previous menu

The LINK SET-UP MENU configures the link connections on this P1700. The options displayed for this menu will vary depending on what interface modules are installed in this router.

1 - Physical link type

The Physical Link Type option displays the type of interface module installed for this link. This is a display-only item and may not be changed.

Values: BRI

2 - Link Operation

The Link Operation option toggles between [enabled] and [disabled] to allow this link to be used for connections.

Default: [enabled]

3 - Logical ISDN Type (if BRI module installed on this link)

The ISDN option is used when a switched (dial up) ISDN service is connected to the BRI module; please see previous Link Set-up Menu for a description of this option.

The Digital_Leased option is used when a permanent leased ISDN circuit is available from your ISDN service provider and is connected to the BRI module. A digital leased circuit is permanently established by your service provider and does not require ISDN phone numbers or dialing functionality. When a digital leased circuit is established, the P1700 will treat it as if it were a normal 64 Kbps leased line connection for each assigned B-channel.

When this link is set to use digital leased circuits instead of switching circuits, the ISDN call establishing functions are not displayed on the menu.

Default: [ISDN]

Values: ISDN, Digital_Leased

Page 49

Menus Reference Manual: Link Set-Up Menu

Considerations:

The following options appear if an ISDN module is present and Logical ISDN Type is set to Digital_Leased: 4 – Frame Relay

The Frame Relay option allows you to select between a frame relay circuit or a PPP leased circuit to configure the router to match the type of service connected to this interface module.

Default: If International software loaded: [disabled] – router is in Leased Line mode.

If North American software loaded: [enabled] – router is in FrameRelay mode.

The router will request confirmation of the change when this menu item is selected, enter “yes”

Considerations:

The state of the Logical Leased type option is saved when performing a software upgrade. This means that when the P1700 restarts, it will return to the operation state that was enabled before the upgrade was performed.

5 – Frame Relay Set-Up

The Frame Relay Set-up option takes you to the Frame Relay Set-up menu where frame relay LMI parameters may be set.

Note: this option appears only if the ISDN Type is set to Digital Leased and FrameRelay is enabled. 5/6 - Phantom Power Detect

Most NT-1s provide a signal to the connected ISDN device to indicate that the NT-1 is powered up and functioning correctly. This signal is generally called phantom power. Some NT-1s do not support phantom power. This option should be disabled if the NT-1 connected to the ISDN link module does not support phantom power.

If the P1700 is having difficulty obtaining a connection to the NT-1, this option should be disabled.

Default: [disabled] Considerations: This option will not appear when the link module is an ISDN type U interface. 6/7 - Link B Channel

When the digital leased circuit option is configured on an ISDN BRI link, the ISDN B-channels must be assigned to

link numbers for normal operation. When a B-channel on the BRI is assigned to a link number, the P1700 then treats

the ISDN B-channel as a 64 Kbps leased line connection. If only one B channel is set to digital leased and the other is

set to ISDN, then the B channel is automatically assigned and is not changeable (B1 for even link numbers, B2 for odd

links). If both B channels on the BRI are set to digital leased, the B channels may be assigned as follows:

Link 1 may be assigned B-channel 1, B-channel 2 or both.

If link 1 is assigned B-channel 1, the other channel is available to service link 2 on the ISDN module; if link 1 is

assigned B-channel 2, the other channel is not available.

This option is available only when the Digital Leased Circuit option is enabled.

Page 50

Menus Reference Manual: Link Set-Up Menu

Enter :

B1, B2, B1-B2

If B-channel 2 has not previously been assigned to the odd numbered link on this ISDN module, the even numbered

link may be assigned B-channel 2 or none.

If link 2 is assigned none, it is not available for user data connection.

This option is available only when the Digital Leased Circuit option is enabled.

Enter :

B2, none

Considerations:

If B-channel 2 is already claimed by link 1 and you wish to reassign it to link 2, you must first reassign B1 to link 1 (select “B1”); otherwise, the following error display will appear:

Error: B2 is currently allocated to first link

The Physical Link Type option displays the type of interface module installed for this link. This is a display-only item and may not be changed.

Values: V.35, RS232, RS530, V.11, G.703, LXT441-CSU, ATL-CSU, T1/E1 2 - Link Operation

The Link Operation option toggles between [enabled] and [disabled] to allow this link to be used for connections.

Default: [enabled]

3 – Frame Relay (if a V.35, RS232, RS530, V.11, G.703, T1/E1, LXT441-CSU or ATL-CSU module is installed on this

link)

The Frame Relay option toggles circuit operation between frame relay and PPP leased to configure the router to match

the type of service connected to this interface module. When this operation is selected, the router will request

confirmation of the change; enter “yes” to confirm.

When this link is set to use Leased instead of Frame Relay, the Frame Relay connection establishing functions are not

displayed on the menu.

Default: If International software loaded: [disabled] – circuit is in leased line mode.

If North American software loaded: [enabled]- circuit is in Frame Relay mode.

Values: FrameRelay, Leased

Considerations:

Page 52

Menus Reference Manual: ISDN Set-Up Menu

4 – Frame Relay Set-Up

The Frame Relay Set-up option takes you to the Frame Relay Set-up menu where autolearning may be disabled and LMI parameters set.

Note: this option appears only if the router has a leased line module installed on this link and Logical Leased Type is set to FrameRelay.

The following option appears if a G703 interface module is installed on this link:

4/5- Link mode

The Link mode option sets the clock mode for a G703 interface on the link.

Default: [master]

Choices: master, slave

4/5 – T1/E1 Set-Up

If this P1700 has a T1/E1 interface, this option takes you to the T1/E1 Set-up menu where T1/E1 parameters may be configured.

4/5/6 - Link Speed

The Link Speed option allows you to define the clock speed generated internally by the bridge/router for the link.

The link will clock both transmit and receive data from the clock it receives from the DCE device.

This internally generated clock may be used to clock this bridge/router and a partner bridge/router by using a custom

back-to-back cable to connect the two bridge/routers together. This back-to-back connection is usually required only

for testing purposes.

Choices: 9.6, 14.4, 19.2, 48, 50, 56, 64, 72, 76, 100, 128, 256, 384, 512, 768, 1024, 1544 and 2048 Kbps.

Default: [64 kbps]

Considerations:

The speed option is not available when an LXT441-CSU module is installed for this link.

4/5/6/7 - Link CD Wait Time

The Link CD Wait Time option specifies the time the bridge/router will wait for Carrier Detect on the link. This is

used primarily when modems must cycle through various speeds to find the one used for the link.

Default: [60 sec]

Range: 0 to 255 seconds

Considerations:

The CD wait time option is not available when an LXT441-CSU or T1/E1 module is installed for this link.

Page 53

Menus Reference Manual: ISDN Set-Up Menu

4/5/6/7/8 - Loop compensation

The Loop Compensation option inverts the transmit clock signal generated by the interface module. This may be required to compensate for phase shifts between the clock signal and transmitted data signal; a problem that may show up as a large number of CRC errors when attempting to operate the connection at speeds greater than 64 Kbps.

Default: [disabled]

ISDN SET-UP MENU

Option Value Description

1. Dial prefix [none] - Set dial prefix

2. Phantom power detect [disabled] - Detect phantom power

3. Force 56k [disabled] - Force 56k rate adaptation

4. Directory number [none] - Set directory number

5. SPID [none] - Link service profile identifier

Enter option number, “=“ - main menu, <TAB> - previous menu

The ISDN SET-UP MENU provides for stored ISDN number set-up. Note: this menu appears only if this router has an ISDN module installed and its Logical ISDN type is set to ISDN (not

Digital Leased).

1 - Dial Prefix

The Dial Prefix option is used when the ISDN P1700 is attached to an ISDN PBX. If a dialing prefix is required before

an outside line is obtained, the dialing prefix must be entered here.

Default: [none]

2 - Phantom Power Detect

Most NT-1s provide a signal to the connected ISDN device to indicate that the NT-1 is powered up and functioning

correctly. This signal is generally called phantom power. Some NT-1s do not support phantom power. This option

should be disabled if the NT-1 connected to the ISDN link module does not support phantom power.

If the P1700 is having difficulty obtaining a connection to the NT-1, this option should be disabled.

Default: [disabled]

Considerations: This option is not available when the WAN module is an ISDN type U interface.

3 - Force 56K

This option forces both B-channels on this router to use V.110 rate adaption for incoming and outgoing calls.

If the path to a destination number passes through a 56 Kbps digital circuit or the destination itself is a 56 K switched

digital service, V.110 rate adaption must be performed to allow the data to be sent at 56 K on the 64 K ISDN lines.

When an ISDN call is placed, the local ISDN service must be informed that V.110 rate adaption is required to fully

complete this connection.

Note: Adding a percent symbol “%” in the ISDN number will cause the P1700 to send a message to the local ISDN

service requesting V.110 rate adaption.

Default: [disabled]

Page 55

Menus Reference Manual: ISDN Set-Up Menu

4 - Directory Number

Enter the ISDN number of the B-channel (up to 15 characters). The ISDN number is available from the ISDN circuit

provider. For a type NI-1 switch, enter only the local portion of the directory number, unless the area code is required

for local calls.

When the Directory Number is changed, a Soft Reset must be performed for this to take effect. The router will be

reset and begin operation with the new directory number.

Default: [none]

Note: in Net3 ISDN environments with BACP enabled, directory numbers must be configured for BACP to function.

The following option appears when an ISDN type is installed and the switch type is set to NI-1, NI-2, DMS-100 or 5ESS-MP:

5 - SPID

Enter the ISDN Service Profile Identifier (SPID) number assigned to this B-channel. The SPID number is available

from the ISDN circuit provider.

When the SPID is changed, a Soft Reset must be performed for this to take effect. The router will be reset and begin

operation with the new SPID.

LINK SET-UP 1 FRAME RELAY SET-UP MENU

Option Value Description

1. Auto-learning [disabled] - Enable/disable LMI and DLCI learning

2. LMI type [ansi] - Network interface

3. Polling interval [10 sec] - Request network status

4. Enquiry interval [6] - Full status enquiry

5. Error threshold [3] - Enquiry failure tolerance

6. Monitored events [4] - Error count interval

Enter option number, “=“ - main menu, <TAB> - previous menu

The FRAME RELAY SET-UP MENU allows the configuration of the frame relay parameters for the link. The options displayed in this menu will depend on the Auto-Learning setting selected

Note: this menu will be displayed if this link has Frame Relay enabled in the Link Set-UP Menu.

1 - Auto-Learning

The Auto-Learning option toggles between [enabled] and [disabled] to allow this frame relay router to try to auto-learn

the LMI type as well as the configured DLCI values on the frame relay service.

When the frame relay router first starts up it will query the frame relay service to try to determine the LMI type. Once

the LMI type is determined, the PVC configurations will be known from the full status inquiry messages. If the DLCI

numbers of the PVC’s on your service are determined during startup, the P1700 will automatically create a remote site

profile for each PVC. The automatically created remote site profiles will be named “LinkxDLCIyyy” where x is the

physical link number the PVC is on and yyy is the DLCI of the PVC. These automatically created remote site profiles

may be renamed for easier usage by changing the Remote Site Alias within the Edit Remote Site menu.

Default: [enabled]

Considerations:

If during this learning process the maximum number of remote sites has been reached, the P1700 will prompt you that there are no remote sites available. A new remote site cannot be auto-created unless one of the existing remote sites is manually deleted. To remove a particular remote site, the PVC for that site must first be disabled (option 8 of the Main/Configuration/WAN set-up/Remote Site/Edit Remote Site/Connection set-up menu), then removed (option 4 of the Main/Configuration/WAN/Remote Site set-up menu). All remote sites on a link may be cleared by toggling the enable/disable function for the link, toggling the enable/disable function for autolearning, or doing a soft reset.

Note: Auto-leaning with PPP Frame Relay is not compatable with some earlier model routers. In case of problems with

auto-learning, try switching to raw 1490 frame relay operation (disable PPP for the remote site connection).

Page 57

Menus Reference Manual: Frame Relay Set-Up Menu

2 - LMI Type

The LMI Type option specifies the type of Link Management Interface in use by the Frame Relay service provider for

the Frame Relay service.

When the LMI type is set to none, the P1700 simply creates frame relay packets and sends them on the defined PVCs.

The links are not checked for errors. There is no congestion control checking. The link is only monitored for control

signals.

Default: [none]

Choices: ansi, ccitt, lmi, none

Considerations:

The “ansi” LMI type operates as defined in the ANSI T1.617 Annex D specification and supports only permanent virtual circuits.

The “ccitt” LMI type operates as defined in the ITU-T Q.933 Annex A specification and supports only permanent virtual circuits.

The “lmi” LMI type operates as defined in the “Frame Relay Specification with Extensions Based on Proposed T1S1 Standards” specification and supports only permanent virtual circuits.

The following options are only displayed if the auto-learning option is set to “disabled” and the LMI type is set to a value other than “none”:

3 - Polling Interval

The Polling Interval option specifies the time interval at which the P1700 will poll the Frame Relay switch for the

management status.

Default: [10 sec]

Range: 5 to 30 seconds

4 - Enquiry Interval

The Enquiry Interval option specifies the frequency at which the P1700 will request a full status update from the Frame

Relay service. The Enquiry Interval is expressed in numbers of Polling Intervals. By default, every 6th poll will be a full

status update instead of just a management update.

Default: [6]

Range: 1 to 255

5 - Error Threshold

The Error Threshold option specifies how many unanswered status inquiries to send to the Frame Relay switch before

determining that the link has failed.

Default: [3]

Range: 1 to 10

Page 58

Menus Reference Manual: Frame Relay Set-Up Menu

6 - Monitored Events

The Monitored Events option specifies the number of status inquiries that are to be monitored when determining the

Error Threshold. By default, if the P1700 does not receive responses to 3 of the last 4 status inquiries, the link will be

considered failed.

Default: [4]

Range: 1 to 10

The T1/E1 SET-UP MENU allows the configuration the T1/E1 link connections on this P1700. Because the options displayed for this menu will vary depending whether the link is operating in T1 or in E1 mode, both displays are shown above.

1 – Link Mode

The Link Mode option sets the router to operate as a T1 or an E1 carrier service interface.

Default: North America: [T1]

International: [E1]

Page 60

Menus Reference Manual: T1/E1 Set-Up Menu

2 – LBO

If this is a T1 link, the LBO option lets you select line build-out required. Line build out modifies the strength and shape of the transmitted signal to compensate for line losses, so that the received signal is within required specifications. A number of different options are available to meet standards for T1 long haul (direct connection to service providers central office facility), T1 short haul (connection through a local PBX), AT&T TR64211 specification long haul and AT&T TR64211 short haul. Your service provider will tell you which specification their service requires. Short haul LBOs are listed as the length of the cable run (in feet) between the router and the local exchange.

E1 service does not require line build out selection. When operating in E1 mode, this option displays 120 ohms and cannot be changed (display only)

Choices: L0db, L7.5db, L15db, L22.5db – T1 long-haul LBOs.

S0to110ft, S110to220ft, S220to330ft, S330to440ft, S440to550ft, S550to660ft – short haul LBOs

short-haul connection

Default: [L0db]

3 – T1 Framing

The T1 Framing option allows you to select between D4 Super Frame and Extended Super Frame modes of T1 framing, or to select unframed for unchannelized use of the link.

Choices: SF, ESF, Unframed Default: [ESF]

3 – E1 Framing

E1 Framing allows you to select between framed and unframed use of the link.

Choices: Framed, Unframed Default: [Framed]

4 – Speed

The Speed option allows you to select the channel data transmission/reception rate to be used over the link. The channel rate will depend on the line encoding format selected. Normally, 56K is used with AMI or inverted AMI encoding, 64K is used with B8ZS or HDB3. The channel rate will likely be specified by the service provider.

Choices: 56K, 64K Default: [64K]

5 – E1 CRC4

The E1 CRC4 option toggles 4 bit crc checking on each E1 frame between enabled and disabled.

Page 61

Menus Reference Manual: T1/E1 Set-Up Menu

5/6 – Slot/Channel Set-Up

This option taskes you to the Slot/Channel Set-Up menu, where the number of channels / time slots to be used and their operating parameters may be selected.

6/7 – Line Encoding

The Line Encoding option sets the line-coding format used. Line encoding requirements will be specified by your service provider.

Choices: if T1: AMI, INV_AMI, B8ZS

if E1: AMI, INV_AMI, HDB3

Default: if T1: [B8ZS]

if E1: [HDB3]

7/8 – Clocking

The Clocking option selects the source for the data transmission timing and sychronization clock (received data is clocked from the received signal).

Network timing loops the received data clocking back to the network for transmission clocking. This setting will normally be used over links from a service provider.

Internal clocking uses the oscillator on the T1/E1 interface of this router to provide the clock signal for transmitted data. This setting could be used on a private line end to end link, with one end providing the clocking (the other end would be set to network clocking).

Choices: network, internal Default: [network]

8/9 – Alarm Generation

This option toggles this routers ability to generate yellow Carrier Failure alarm notifications after detecting received signal errors.

9 – T1.403 PRM

This option toggles ANSI specification T1.403 CSU performance reporting between enabled and disabled. If enabled, peformance data is transmitted once per second.

Page 63

Menus Reference Manual: Slot/Channel Set-Up Menu

3 – Start

The Start option specifies the first timeslot or channel number to be used. The remainder of the channels up to the number selected will be filled sequentialy.

Choices: if T1: from 1 to 24

if E1: from 1 to 30 if timeslot 16 unavailable, 1 to31 if timeslot 16 available

note: the options displayed for a start number will only be those such that the start number plus number of channels is less than or equal to the total number of channels on the service (24 for T1, 30 or 31 for E1)

Default: [1]

4 – Allocation

If the number of channels used is set to half or less than the total channels on the service, this option allows the channels to be allocatd as a contigous block or as alternating used and unused channels. Your service provider will specify which they prefer. The most common use of alternate channel allocation is to meet pulse density requirements for a 64 Kbps per channel link with AMI or inverted AMI encoding.

Default: [contigous] note: this option appears only if the number of channels is:

T1 – 12 or less E1 slot 16 available, odd start number – 16 or less E1 slot 16 available, even start number – 15 or less E1 slot 16 unavailable, odd start number – 15 or less E1 slot 16 unavailable, even start number – 14 or less

If E1 timeslot 16 is toggled from available to unavailable after the maximum number of alternating timeslots has been

set, allocation will automatically revert to contiguous.

4/5 – Speed

The Speed option displays the data rate per channel selected in the T1/E1 set-up menu. This option is display only and cannot be changed here.

5/6 – E1 Timeslot 16

Some E1 service providers reserve timeslot 16 for line management. If your service specifies that timeslot 16 is for their use, toggle this option to reserved.

Enter option number, “=“ - main menu, <TAB> - previous menu

The REMOTE SITE SET-UP MENU allows the display, configuration, and creation of remote site profiles. Remote site profiles are used to establish PPP connections to other PPP routers. The appearance of this menu will vary depending on the interface modules installed and their configuration.

Important: When configuring this P1700 to be the originator of PPP ISDN calls or leased line connections, always define a

remote site for each of the possible remote partner routers that this P1700 may connect to. For Frame Relay connections, remote site profiles are created automatically if auto-learning is enabled. If auto-learning is disabled, then frame relay remote sites must be manually configured as well. Each of the remote sites created stores all of the configuration information required to properly maintain the PPP connection to that remote PPP router. The remote site alias is used to match against the incoming user name during authentication. If an authenticated user name is the same as one of the configured remote site profiles, that connection will use the configuration defined within the remote site profile.

The configuration parameters for a remote site profile may be set by using another profile as a template. Three remote site table entries have been reserved for ISDN, leased line and Frame Relay remote site profile templates; these are:

ID number remote site name

129 ISDN_TEMPLATE 130 FR_TEMPLATE 131 LEASED_TEMPLATE

Parameters for these profiles may be set under the “Edit Remote Site“ menu option If a number of remote sites will have a similar profiles, copying the remote site profile from a template can save considerable time in setting them up.

If this router has an ISDN BRI interface and it is set for Digital Leased Circuit, the ISDN B-channel will be treated as a leased line connection.

When the P1700 receives an incoming ISDN call, the Multilink state is taken from the “ISDN_TEMPLATE” remote site profile. After the authentication process is finished, if the remote site is a valid remote site that has already been configured, the remaining call parameters are taken from the configured remote site profile. If the remote site does not match one of the configured remote site profiles, then the remaining call parameters will be taken from the “ISDN_TEMPLATE” remote site profile and a remote site profile for that link will be dynamically created at the next available remote site ID number. The newly created remote site profile will be named “INCOMING n” where “n” is the next unassigned Initial Profile number (n will be between 1 and 2).

When CallerID security is enabled, an incoming call will not be accepted if the remote site does not match one of the configured remote site profiles.

Page 66

Menus Reference Manual: Remote Site Set-Up Menu

When displaying status or statistic information on the connections to a remote site PPP router, most of the information is displayed according to a particular remote site. Within the Statistics section, a remote site is chosen and then the information for that connection may be displayed. The name of the remote site that the connection has been attached to may be viewed in the Event log file available within the Network Events menu.

There are 128 configurable remote sites available. Each of these remote sites will have a remote site alias associated with them. When a connection is made to a particular remote site, the call will be attached to that remote site profile after the connection has been established. Statistics for a connection are stored under the remote site profile alias or ID number.

Three remote site profiles, numbered 129 through 131, are reserved as templates that may be used for faster remote site configuration.

Remote Site ID Remote Site Alias Description

1 - 128 (user configurable) Remote site used for outgoing connections to these specific remote sites.

Configuration parameters for the outgoing connection are taken completely from the parameters defined in the remote site profile.

Remote site profile used for incoming connections that have been authenticated and the incoming user name matches the name of one of the configured remote sites.

129 ISDN_TEMPLATE Remote site profile used to set up a template that may be used to configure remote

sites with ISDN connections. Multilink state is taken from this profile. If the incoming user name matches the name of one of the configured remote sites, the remaining call parameters will be negotiated from the values defined for that remote site.

If the incoming user name does not match any of the remote sites defined, the connection is attached to the INCOMING profile for that link (132 through 145). The remaining negotiating parameters, such as BCP, IPCP, IPXCP, and CCP, will be taken from the ISDN_TEMPLATE settings.

130 FR_TEMPLATE Remote site profile used to set up a template that may be used to configure remote

sites with Frame Relay connections. If autolearning is enabled, this template will be used to auto-create each site learned. Site id numbers are assigned sequentially starting from the first available site number in the remote site table.

131 LEASED_TEMPLATE Remote site profile used to set up a template that may be used to configure remote

sites with Leased Line connections.

For incoming connections, a remote site profile is auto-created at the first available

location in the remote site table.

2 - Activation Set-Up

The Activation Set-up option takes you to the Activation Set-up menu for the chosen remote site, where activation conditions are defined for the main connection to this remote site. The activation conditions for the primary connection consist of the activation schedule, which determines when the connection may be operational, the usage limits and the load thresholds at which the link will be brought up or down.

The Activation conditions are not applicable when placing a manual call to this remote site.

Note: This option does not appear for site profiles with a Frame Relay, PPP disabled connection.

Menus Reference Manual: Edit Remote Site Menu – Connection Set-Up Menu

3/4 - Security Parameters

The Security Parameters option allows you to set the password that this remote site will use for incoming security authorization and to set a user name and password for outgoing security authorization.

Note: This option will not appear if the remote site is configured for raw 1490 frame relay. Routers configured to have a leased line link operating in conjunction with an ISDN B-Channel (either as backup or bundled link) must have security enabled and with the proper usernames and passwords entered on both partner routers.

4/5- Remote Site Alias

The Remote Site Alias option defines the name used to represent this remote site. The remote site alias is used to match against the incoming user name during authentication. If an authenticated user name is the same as one of the configured remote site profiles, that call will use the configuration defined within the corresponding remote site profile.

The remote site alias is case sensitive and may consist of 1 to 16 alphanumeric characters. Use the underscore character instead of a space character.

5/6 – Connection

The Connections option defines the type of connection and its usage.

Options: single_link, dual_link, threshold, recovery, threshold_with_recovery.

Single link operation: only one link (the primary link) will be used for connection to this remote site.

Dual link operation: Two links will be available for connection to this remote site; both will be brought up any time a connection to this site is established.

Threshold: traffic levels on the primary link will be use to determine whether or not to bring up the secondary link. The conditions controlling the secondary link are set under the Activation menu. This option is not available with raw 1490 Frame Relay (PPP Encapsulation must be enabled).

Recovery: The secondary link will be used as a backup connection in case of failure of the primary link. The conditions controlling the secondary link are set under the Activation menu.

Threshold with recovery: the secondary link will be brought up if traffic on the primary link exceeds a threshold level or if the primary link fails. The conditions controlling the secondary link are set under the Activation menu.

Considerations: The “threshold with recovery” option is not compatible with partner routers that are configured to have

only “threshold” or only “recovery” available on the link. If a connection of this type is attempted, the link will bob when the connection criteria are met for one router but not for the other. For example, if one is set for “threshold_with_recovery” and the other is set only for “recovery”, when the threshold is exceeded the router with “threshold_with_recovery” will attempt to bring up the connection, but because the partner router is not set for threshold activation, the partner router will bring the connection down.

6/7 – Primary connection

The Primary connection option defines what type of service will be used on the primary connection. If the currently selected primary link is not configured for the chosen connection type, a warning is displayed: the connection will not be established if the link is not configured for the chosen connection type.

Options: Frame_relay, Leased, ISDN_call

7/8 – Secondary Connection

The Secondary connection option defines what type of service will be used on the secondary connection. If the currently selected secondary link is not configured correctly for the chosen connection type, a warning is displayed. The primary connection will still be established even if the secondary connection is not correctly configured.

Options: Frame_relay, Leased, ISDN_call Note: this option is user configurable only if the connection is not single link. If the connection is single link, the option

becomes display only with *[none] displayed.

8/9 - Remote Site Type

The Remote Site Type option defines whether spoofing is enabled or not with this remote site connection.

Options: interoperable, spoofing Note: this option is user configurable only if the primary connection is ISDN_call type, otherwise this option is display

only. Considerations: If you are running spoofing with Triggered RIP, both routers must be set to Triggered RIP

“link_up_only”. The P1700 will automatically configure to this setting but the remote partner router should be checked to make certain that it is correctly configured.

Enter option number, “=“ - main menu, <TAB> - previous menu

This version of the REMOTE SITE CONNECTION SET-UP MENU allows the setting of frame relay parameters used to configure the Permanent Virtual Circuit (PVC) that is used to connect to this remote site. Up to 128 remote site PVCs may be defined.

1 - Primary Link

The Primary link option defines the primary link number that will be used to connect to this remote site.

Options: 1, 2, none Default: [none]

Considerations:

The PVC must be toggled (disable – enable option 7. State) before this option may be takes effect.

2 - DLCI

The Data Link Connection Identifier (DLCI) option specifies the Frame Relay LAPF address for the PVC. This value must be set to be the same as the value provided by the Frame Relay network provider.

When the frame relay router first starts up it will query the frame relay service to try to determine the LMI type. Once the LMI type is determined, the PVC configurations will be known from the full status enquiry messages. If the DLCI numbers of the PVC’s on your service are determined during startup, the P1700 will automatically create a remote site profile for each PVC. The automatically created remote site profiles will be named “LinkxDLCIyyy” where x is the physical link number the PVC is on and yyy is the DLCI of the PVC.

Default: [16] Range: 16 to 991

Considerations:

The PVC must be toggled (disable – enable option 7. State) before this option may be takes effect.

Page 78

Menus Reference Manual: Edit Remote Site Menu – Connection Set-Up Menu

3 - CIR

The Committed Information Rate (CIR) option specifies the data rate that the Frame Relay service has guaranteed to provide.

This value must be set to the same as the value provided by the Frame Relay network provider. If the Frame Relay network provider supplies values for Bc and T only, simply calculate the CIR value by using the following formula: CIR = Bc/T.

Default: [0 k] Range: 0 to 2048 Kbps

Considerations:

When changing the CIR option for this PVC, the PVC must be toggled (disable – enable option 7. State) before the new value will take effect.

The value of 0 indicates that there is no commitment on the data rate.

The actual CIR may exceed the configured CIR because only complete frames are

transmitted. Frames will not be broken to fit within CIR when the upper limit is met, the

final frame will be transmitted in full. The only time this does not happen is when traffic

exceeds CIR + EIR, in which case the frame which would cause CIR to be exceeded will not

be transmitted.

The only restriction is that CIR + EIR > 0

4 - EIR

The Excess Information Rate (EIR) option specifies the data rate that the Frame Relay service indicates may be available for this PVC.

This value must be set to the same as the value provided by the Frame Relay network provider.

Default: [“link_speed”] Range: 0 to 2048 Kb, “link_speed”

Considerations:

When changing the EIR option for this PVC, the PVC must be toggled (disable – enable option 7. State) before the new value will take effect.

When EIR = 0, no excess burst data is allowed to be transmitted. If EIR is non-zero, bursting is allowed. The only restriction is that CIR + EIR > 0

Page 79

Menus Reference Manual: Edit Remote Site Menu – Connection Set-Up Menu

5 - Time Interval

The Time Interval option specifies the time period (in 10ths of a second) that the P1700 uses for monitoring PVC bandwidth.

This value must be set to the same as the value provided by the Frame Relay network provider.

Default: [10 1/10th sec]

Range: 10 to 40 1/10th second

6 - PPP Encapsulation

The PPP Encapsulation option enables the P1700 to send data to this remote site using the Point to Point Protocol (PPP) over frame relay. When this option is disabled, the P1700 will send data to this remote site using standard RFC1490 frame relay frames.

Default: [disabled]

Considerations:

When this P1700 is configured with PPP Encapsulation disabled and the remote site router has PPP enabled, this P1700 will bring the PVC up and there will be no indication that the connection negotiation is not proceeding. This local P1700 will indicate that the PVC is up, however there will be no traffic sent over the PVC. If the remote site router is an router, the remote site router will continue to display the alarm “PPP connection attempt to remote site n” until the connection is established.

7 - State

The State option toggles between [enabled] and [disabled] to activate the PVC or take the PVC out of service.

Default: [enabled]

When changing the EIR option for this PVC, the PVC must be be toggled (disable – enable option 8. State) before the new value will take effect.

When EIR = 0, no excess burst data is allowed to be transmitted. If EIR is non-zero, bursting is allowed. The only restriction is that CIR + EIR > 0

6 - Time Interval

The Time Interval option specifies the time period (in 10ths of a second) that the P1700 uses for monitoring PVC bandwidth.

This value must be set to the same as the value provided by the Frame Relay network provider.

Default: [10 1/10th sec]

Range: 10 to 40 1/10th second

7 - PPP Encapsulation

Default: [disabled]

Considerations:

8 - State

The State option toggles between [enabled] and [disabled] to activate the PVC or take the PVC out of service. You must confirm that this is the action you wish to take by typing “yes” at the prompt.

Default: [enabled]

The REMOTE SITE ISDN CALL SET-UP MENU allows the setting of parameters used for ISDN call establishment to the remote site PPP router. This menu is not displayed when the Digital Leased Circuit option is enabled for the ISDN interface.

1 – Advanced Settings

This option takes you to the Advanced Settings menu where callback delay and redial parameters may be set.

2 - ISDN Number

The ISDN Number option defines the ISDN number to be called to establish a connection to the remote partner PPP router.

Default: [none]

3 - Alternate ISDN Number

The alternate ISDN number is used for two different situations when Multilink operation is set to enabled for this remote site.

1. ISDN number called when Bandwidth on Demand settings require a second ISDN call to be made after an initial

Auto-Call or IP Address Connect call has been placed to the remote site. When the secondary connection is enabled by selecting the ISDN_call option, the first ISDN Number will be used to place the first ISDN call according to the IP Address Connect table, and the Alternate ISDN Number will be used to place the second ISDN call according to the Bandwidth on Demand options defined within the Secondary Activation menu.

2. ISDN number called when both the primary and secondary connections are set to ISDN_call and an Auto-Call or

IP Address Connect call is placed. This will cause this alternate ISDN call to be placed to the remote site PPP router once the main ISDN call has been established and Multilink operation has been successfully negotiated.

Default: [none]

Page 84

Menus Reference Manual: Edit Remote Site - Connection Set-Up – ISDN Call Set-Up Menu

4 - Group

The Group option specifies which group number will be used to make calls to this remote site connection. If hunt group numbers are not used, it is recommended that when using callback between this P1700 and a remote site router with only a single BRI, that the links on this P1700 be configured into groups of two links. If the links are grouped more than two to a group, a callback request may come in to one ISDN number in the group but be responded to by another link with an ISDN number that is not either the primary or alternate ISDN number that the remote site uses to call to this router. The callback will be rejected by the remote site router in this case. Groups are set up under the Link Set-up Menu.

Default: [1]

Options: 1 or 2

5 - Wildcard

The Wildcard option defines the ISDN number used when checking for a match on an incoming callerID identified call. The incoming call is checked for a match against the configured values for the ISDN number, the alternate ISDN number, and then the wildcard number.

This wildcard number may contain don't care values to allow for a broader matching possibility. Don't care values are defined with an "X" in the wildcard number. When the P1700 checks the incoming call's callerID against this wildcard value, the P1700 starts at the rightmost digit and checks each digit from there. The number of digits compared is determined by the ISDN number with the least amount of digits. This means that the checking will only be done to the maximum number of digits of either the incoming callerID or the wildcard value, whichever is less.

For example: The wildcard value is set to 931-1XXX. Refer to the following list for accept and reject examples.

Incoming callerID Result

328 accepted 931-1328 accepted 2328 rejected 555-1212 rejected

Default: [none]

6 - Call You

Dialing prefix used to make the ISDN call to the remote site PPP router. The Call You dialing prefix is used to define the area codes, country codes, long distance dialing prefixes, or any other information required to establish an ISDN call to the remote site PPP router.

Default: [none]

7 - Call Me

Dialing prefix used by the remote partner router to make an ISDN call to this P1700. When Connection Management is enabled, this ISDN P1700 will pass its directory numbers as well as the Call Me dialing prefix to the remote partner ISDN router. This allows the remote partner ISDN router to correctly dial this P1700 when the ISDN circuit needs to be resumed.

The Call Me dialing prefix is used to define the area codes, country codes, long distance dialing prefixes, or any other information required for the remote partner ISDN router to establish an ISDN call to this ISDN router.

Default: [none]

Note: When CMCP is enabled, the call me prefix to get back to the partner router must be entered so that the link can be

re-established after suspension (only the directory number is passed when the call is set up, not the entire connection number). For the same reason, the partner router must also have its call me prefix entered.

Page 85

Menus Reference Manual: Edit Remote Site - Connection Set-Up – ISDN Call Set-Up Menu

8 - Callback

The Callback option when set to enabled causes this router to refuse an incoming ISDN call for this remote site profile and then initiate an outgoing ISDN call to this remote site. Once a match of an incoming ISDN call is made to an existing remote site profile, the matching remote site profile is checked to determine whether the incoming call is answered or refused and a callback ISDN call initiated.

Callback to this remote site may also be triggerred by a call from another source, such as a voice phone. In this case, the number of the voice phone used to trigger the callback would be entered in the Wildcard option (4).

The Callback option may be used to provide a single point of ISDN billing. By allowing only one of the routers to establish ISDN calls, the ISDN charges may be centralized in one location.

The CallerID option when enabled will take precedence on determining whether an incoming call is ignored or answered. When calling back this remote site, both the ISDN number and the alternate ISDN number will be tried.

Default: [disabled].

Considerations:

For this feature to operate, the ISDN service provider must supply the caller’s number. Check with your ISDN service provider to see whether this service is available. For callback from a P1700 to a remote site router with only a single BRI to operate properly, the P1700 must either have a hunt group number that the remote site router can call or the ISDN links must be set up in groups of two. If this is not done, the remote site router can call in to the P1700 on one of up to 4 ISDN numbers; the callback will be made from the first available ISDN link. This may not be the number that the remote router uses as the primary or alternate ISDN, which means that the call will be rejected.

Option Value Description

1. Callback delay [2 s] - Time to wait until callback

2. Redial timer [10 s] - Time to wait until redial

3. Redial count [5] - Number of redials to try

1 – Callback Delay

The Callback Delay option specifies the number of seconds that this router will wait before making a call in response to a callback request call from the remote site router. This allows sufficient time for the originating call to complete its disconnect before the response call arrives.

Default: [2 sec]

Range: 1 to 20 seconds

2 - Redial Timer

The Redial Timer option specifies the time the router will wait before attempting to redial an incomplete ISDN call.

Default: [10 sec] Range: 4 to 255 seconds

Considerations:

When the ISDN switch type is set to KDD or NTT, the default, and minimum redial timer value is 90 seconds.

3 - Redial Count

The Redial Count option specifies the number of times the router will attempt to redial an incomplete ISDN call.

Default: [5] redials Range: 0 to 255 redials

Page 87

Menus Reference Manual: Edit Remote Site - Connection Set-Up - ISDN Call -Advanced Settings Menu

Auto-Call Considerations:

When two ISDN numbers are defined in the ISDN Call Set-Up menu of the remote site entry, the router will alternate between the two numbers when re-dialing.

When the router attempts to establish an Auto-Call ISDN call and the PPP router at the remote site does not respond, the router will try up to the number of times defined in the Redial Count to establish the ISDN call. The interval between the successive attempts is defined by the Redial Timer. If after the defined number of redials the router cannot establish a call to the remote partner, the router will wait for one minute and then try to establish the ISDN call again using the Redial Count and the Redial Timer values. If the call is not established after these attempts, the router will wait for 2 minutes and then try again. The router will keep trying to establish the call (according to Redial Count & Redial Time) in blocks with the time intervals: 4 minutes, 8 minutes, 15 minutes, 15 minutes, etc.) until the remote partner answers the call.

When the ISDN switch type is set to KDD or NTT, the minimum time between re-dialing blocks is 3 minutes.

When the Redial Count is set to zero (0), the router will redial the remote partner indefinitely at one minute intervals using the defined ISDN numbers for the remote site according to the redial blocks explained earlier. The router will alternate between the two defined ISDN numbers for the partner in blocks of #1, #2 with a time between the two ISDN numbers of 4 seconds.

Address Connect Considerations:

When the router attempts to establish an Address Connect ISDN call and the remote partner does not respond, the router will not attempt to redial the remote partner until the next Address Connect connection is required.

If two ISDN numbers are defined in the ISDN Call Set-Up menu of the remote site entry, the router will dial the alternate ISDN number after waiting 4 seconds if the first ISDN number does not respond.

The ACTIVATION MENU allows the setting of the activation schedule and usage limits for the primary link used to connect to the remote site router. Traffic activation levels may also be set allowing the secondary link to be used when the throughput of the primary link exceeds the defined levels.

Note: the activation schedules of both partner routers on the link must be set up identically. If one is set to be active while the other is not, the active router will continuously try to bring up the link to the partner router, which will reject the connection because its activation table is set to have the connection to that remote site inactive. If the routers are in different time zones, you must decide on a standard time to be used by both.

Page 89

Menus Reference Manual: Edit Remote Site - Activation Set-up Menu

4 - Inactivity Timer

The Inactivity Timer option defines the Connection Management Idle Timer that is used to determine when an ISDN call will be suspended or terminated. This timer monitors traffic on the link. If the link traffic is idle, this router is set to use Connection Management, and there are LAN sessions using the link, the ISDN call will be suspended.

When the Inactivity Timer is set to off, this router will not suspend or terminate the ISDN call. This may be used to allow only one of the routers to monitor the link traffic to determine when to suspend or terminate the ISDN call.

The Inactivity Timer is also used for IP Address Connect configurations. If connection management is not used, the inactivity timer will monitor link traffic. If the traffic on the link is idle for a time longer than the inactivity timer, the link will be terminated and then be made available for the next IP address connect request.

Default: [60 sec]

Range: off, 20 to 3600 seconds

5 - Recovery Timer

The recovery timer sets the delay before the secondary link is activated or deactivated when the primary link goes down or is reestablished. This acts as a stability timer to give the primary link a period to recover before the backup is activated and to ensure that when the primary link is reestablished that it stays up for a significant time before the backup link is dropped.

Default: [15 sec] (note: if Frame Relay is enabled, this default changes to 60 sec.)

Range: 15 to 300 seconds Note: This option will only be displayed if the Connection option in the Edit Remote Site menu is set to “recovery”

or “recovery_with_threshold”.

Enter option number, "=" - main menu, <TAB> - previous menu

The THRESHOLD SET-UP MENU allows the traffic load conditions and stability timers for activating and deactivating the secondary link to be set.

1- Up Threshold

The Up Threshold value determines the percentage of primary link’s capacity that will cause the secondary link to be activated. The primary link must sustain a throughput (either receive or transmit) of greater than the up threshold for a period greater than the up stability timer in order for the secondary link to be activated.

Enter:

Percent of main link capacity (from 50 to 100)

> 80

Default: 80% Note: In a frame relay environment, the link summary statistics used to determine the up threshold may not be

accurate due to the overhead associated with frame relay. The overhead typically adds about 5% at an 80%

line load, meaning setting the up threshold at 80% would cause the secondary link to come up when the

actual transmission rate reaches about 85% of the maximum line rate. If a more accurate data transmission

threshold is required, it may be calculated by using the Frame Relay Protocol Statistics. Go to the Main

Menu/Statistics/WAN Statistics/Remote Site Statistics/Protocol Statistics and page down to the FR

display. Take the greater of the Rcv or Xmt rate (in KB) and divide it by the stated link speed (in KB) *100

to get the recent percent of the link capacity being used for data. By comparing this to the load shown in

the Link Summary Statistics, the amount of overhead may be determined and the threshold adjusted

accordingly.

Page 94

Menus Reference Manual: Edit Remote Site - Activation Set-Up - Threshold Set-Up Menu

2 - Up Stability Timer

To prevent the unnecessary activation of the secondary link if the Up Threshold is only reached for a brief period, the Up Stability Timer is used. It defines how long the primary link’s throughput must be at or above the Up Threshold before the secondary call is activated.

For example, using the default values, if a traffic level above the Up Threshold of 80% is maintained on the primary link for a period of 2-min. (length of time the secondary link is “held inactive”), then the secondary link will be activated.

Enter:

time in minutes when link is down (from 1 to 60)

> 2

Default: 2 minutes

3 - Down Threshold

The Down Threshold determines when the secondary link is shut down again. It must be set lower than the Up Threshold.

After the secondary link comes on-line, it will begin to share the load that would have gone across the primary link. For example, if the primary link brings the secondary link on-line at a threshold of 80%, then both links will be carrying the load.

The Down Threshold looks at the total throughput (both links together) to determine if the second link will be brought down. The total throughput is compared to the throughput of a single link. When the total throughput drops below the Down Threshold, the second link will be dropped.

Enter:

Percent of main link capacity (40 to 95)

> 60

Default: 60%

4 - Down Stability Timer

The Down Stability Timer is similar in operation to the Up Stability Timer. When the total link throughput drops below the value set by the Down Threshold for a period of time defined by the Down Stability Timer, the secondary link will be disconnected and placed back in the stand-by mode.

For example, if the total throughput (both links together) drops below 60% of the bandwidth of a single link (64 Kbps) for a period of 10 minutes, the secondary link will be disconnected.

Enter:

time in minutes when link is up (from 1 to 60)

>10

Default: 2 minutes

Menus Reference Manual: Edit Remote Site - Protocol Menu

6 - BACP Set-Up

The BACP Parameters menu allows you to activate the BACP (Bandwidth Allocation Control Protocol) and set the call conditions used. BACP reduces network charges by adding or dropping the second link based on traffic demands. BACP mediates control of the link between the routers to prevent “link bobbing”.

Note: this option will only be displayed if this remote site connection is configured as ISDN or PPP Leased and the duallink option is enabled.

7 - Multilink Operation

This option determines whether the connection to this remote site will operate using single link protocol or PPP multilink protocol. Multilink protocol allows multiple links to be connected between two routers. The physical links may be of different types (e.g. Leased and ISDN)

Default: [disabled]

ISDN Considerations:

When multilink operation is changed for a group, all active ISDN calls will be disconnected.

When the router receives an incoming call, the Multilink state is taken from the “ISDN_TEMPLATE” remote site profile. Note that if Multilink is disabled in the “ISDN_TEMPLATE” and an incoming call requests Multilink, the router will negotiate to have Multilink enabled.

When a PPP router with Multilink disabled attempts to establish an ISDN connection to an Ascend router with Multilink enabled, the Ascend router will shut down the ISDN call. Simply set the Multilink values on each of the routers to be the same value and then establish the ISDN connection.

Note: if the primary connection for this remote site is frame relay, PPP encapsulation must be enabled for this option to be displayed.
