changes made via another method to be lost.

— If you are making changes and someone else makes changes and

saves them, your changes would be lost.

Specifies the type of service to which the unit is to be connected.

Frame Relay – Frame Relay-aware mode, for connection to a frame relay service. This is the default operational mode, and it is used to configure the FrameSaver unit in frame relay mode so that frame relay parameters and SLV functionality can be set up.

If a 9123 unit is set to Leased Line, then changed to Frame Relay, Time Slot Discovery is temporarily suspended until LMI communication is reestablished, and all frame relay-related configuration options previously set up are restored, except for the Sync Data Port Assignments. In this case, all port assignments set to S1Port-1 are converted to FrameRly1 assignments on the Frame Relay Network 1 Assignment timeslot assignment screen.

Leased Line – Leased-line mode, for connection to a standard leased-line service. This mode provides a simple and straightforward screen to guide the installer during initial installation, and to set up remote access to the unit.

When operating in leased-line mode, no frame relay-related statuses, performance statistics, tests, configuration options, or control features are available; only physical layer functions are available.

If the unit is set to Frame Relay then changed to Leased Line, all frame relay-related screens and features are filtered so they are transparent to the user. All frame relay links, DLCIs. and PVCs are preserved. For 9123 units, all Frame Relay Network 1 FrameRly1 time slot assignments are converted to S1Port-1 on the Sync Data Port Assignments screen.

PPP – Point-to-Point Protocol mode. A single PPP circuit exists between Port1 and Net1.

Changing to or from PPP mode causes a reset.

Using RIP with FrameSaver SLV CSU/DSUs

Using the system’s standard Routing Information Protocol (RIP) feature, routing information is passed to the router over the management PVC, so the router can learn routes to FrameSaver devices. Node IP information should be set up (see

Using the Easy Install Feature on page 2-2).

Procedure

To set up your router and FrameSaver SLV CSU/DSU so that the router can learn routes to FrameSaver devices:

1. Configure the router to receive RIP.

For example, if using a Cisco router, you would use the commands config-t, router RIP, int serialx, IP RIP Receive version 1, then ctl-z WR.

2. Create a Standard DLCI for the user data port.

2. Basic Configuration

Selecting a Frame Relay Discovery Mode

When a Frame Relay Discovery Mode is active, the FrameSaver unit “discovers” network DLCIs from the network LMI status response message. It configures a network DLCI and a user data port DLCI, and automatically connects them to create a PVC.

Main Menu

→ Auto-Configuration→ Frame Relay Discovery Mode

Automatically configured network DLCIs are multiplexed, and each automatically configured port DLCI carries the same DLCI Number as its corresponding network DLCI. These are the same DLCI numbers that would have been available had the FrameSaver unit not been inserted in the link, between your equipment and the network.

NOTE:

A local Management PVC (e.g., the PVC between the router and the FrameSaver unit’s user data port) must be configured manually.

The following will occur when a Frame Relay Discovery Mode is selected:

Discovery Mode Configuration Description

1MPort

Auto-configuration is enabled on Port-1.

A management DLCI is configured.

A multiplexed network DLCI containing two embedded DLCIs (EDLCIs) is configured for Port-1 user data and management data.

A PVC connection is configured between the network and port DLCIs.

Discovery Mode Configuration Description

2. Basic Configuration

NetOnly

Disable

Auto-configuration of a network DLCI only; no Port-1 or PVC connections are configured.

No Port-1, PVC connection, or management DLCI is configured.

No frame relay discovery or automatic configuration takes place.

The FrameSaver unit will be configured manually.

NOTE:

If the default setting (1MPort or 1PPort) is not the setting required for your application, change the Frame Relay Discovery Mode before connecting the network cable or editing discovered option settings. Otherwise, the FrameSaver unit will start discovering DLCIs as soon as it powers up.

If this occurs, you can recover by deleting the discovered DLCIs. If only a local management PVC between the router and the FrameSaver unit has been configured, simply select the desired Frame Relay Discovery Mode and S the change.

The default discovery mode, depending on model, is 1MPort or 1PPort.

When 1MPort mode is active, the unit creates for each DLCI discovered on the network a multiplexed network interface DLCI (which contains two EDLCIs: one for Port-1 data and the other for management), a standard Port-1 DLCI (with the same number as the network interface DLCI), and a Management PVC, then cross-connects them. When LMI is active on the network interface and PVC status information (with provisioned DLCI numbers) is next received from the network, the unit automatically saves the settings to the Current Configuration area.

ave

When 1PPort mode is active, the unit uses the Network DLCI values obtained from the Network LMI status response message to automatically configure for each DLCI a corresponding DLCI for Port 1 having the same numeric value as the Network DLCI, and automatically cross connects them. The DLCIs created on the network side are IP Enabled (not standard or multiplexed) DLCIs. In addition, payload management is configured for the network DLCI and assigned the Node IP Address.

Configuration options set by selecting a discovery mode can be manually modified, refined, or deleted at any time using the Configuration menus. No previously discovered and configured DLCIs or cross-connections will be removed unless authorized or Automatic Circuit Removal is enabled (see Automatically

Removing a Circuit on page 2-16). Additional discovered DLCIs will be configured

according to the current Frame Relay Discovery Mode setting. Selecting or changing the setting will not affect IP Addresses or Subnet Masks.

NOTE:

When auto-configuration creates a multiplexed DLCI, but a standard DLCI is needed, change the DLCI to standard from the network DLCI Records screen:

n If No (n) is entered, or if you exit the screen without responding to the prompt,

no Auto-Configuration updates are performed and updates due to LMI response messages are performed according to the previously saved setting.

Automatically Removing a Circuit

Using the automatic circuit removal feature, which comes enabled, network DLCIs and PVCs can be automatically removed from the unit’s configuration when the network service provider no longer supports them. Automatic deletion is based upon information from a LMI full status response on an active frame relay link.

When this feature is set to:

n Enable – The following will be automatically removed from the unit’s

configuration:

— Unsupported network DLCIs and PVC connections that include

multiplexed network DLCIs.

— Standard network DLCIs that are Payload Managed or IP Enabled.

— Unsupported standard network DLCIs that are not configured as the

primary destination in a management PVC.

— Non-management PVCs in which unsupported standard network DLCIs

are included.

— DLCIs not included in three consecutive LMI full status response

messages.

— LMI status responses that indicate a Deleted status for the DLCI.

All configured options relating to the deleted circuits are also deleted and they revert to their default settings.

A DLCI will not be deleted if the physical interface or frame relay link is down, or if the DLCI is used for the TS Management Link.

n Disable – Unused network DLCIs, PVC connections, and management PVCs

must be manually removed.

If the model has ISDN backup capability, ISDN Link Profiles associated with the deleted records and alternate destinations will be deleted, as well.

LMI Behavior

Possible Settings: Independent, Net1-FR1_Follows_Port-1, Net1-FR1_Follows_Port-2, Net1-FR1_Follows_Rtr-S0, Port-1_Follows_Net1-FR1, Port-2_Follows_Net1-FR1, Rtr-S0_Follows_Net1-FR1, All_Ports_Follow_Net1-FR1, Port-1_Codependent_with_Net1-FR1, Port-2_Codependent_with_Net1-FR1, Rtr-S0_Codependent_with_Net1-FR1,

Default Setting: Independent

Configures the device to allow the state of the LMI to be passed from one interface to another, determining how the unit will handle a change in the LMI state. Sometimes referred to as LMI pass-through.

Display Conditions – Port-n options are available on CSU/DSUs and Rtr-S0 options are available on FrameSaver SLV Routers. Port-2 options are available on units with two data ports.

NOTE: LMI Behavior cannot be changed while Auto Backup is enabled. A warning message appears at the bottom of the screen if auto backup is enabled. First, disable Auto Backup, and then change LMI Behavior.

Independent – Handles the LMI state of each interface separately so that the LMI state of one interface has no effect on the LMI state of another interface. Provides LMI Spoofing. This is the recommended setting when backup is configured, and for Network Service Providers (NSPs).

LMI Behavior (continued)

Net1-FR1_Follows_Port-1 – Brings LMI down on the network interface when LMI on

Port-1 goes down, disabling the network interface and deasserting its control leads. When LMI on Port-1 comes back up, the network interface is reenabled. The LMI state on the network interface has no effect on the LMI state on Port-1. That is, the network interface’s LMI follows Port-1’s LMI. Used at central sites, this setting is useful when the remote site router on the other end of the PVC connection can initiate recovery via a redundant central site when there is a catastrophic central site LAN or router failure. Not recommended for NSPs.

Net1-FR1_Follows_Port-2 – Reacts like the Net1-FR1_Follows_Port-1 selection, but for Port-2 instead.

Rtr-S0_Follows_Port-1 – Brings LMI down on the network interface when LMI on Rtr-S0 goes down, disabling the network interface and deasserting its control leads. When LMI on Rtr-S0 comes back up, the network interface is reenabled. The LMI state on the network interface has no effect on the LMI state on Rtr-S0. That is, the network interface’s LMI follows Rtr-S0’s LMI.

Port-1_Follows_Net1-FR1 – Brings LMI down on Port-1 when LMI on the network interface goes down, disabling Port 1 and deasserting its control leads. When LMI on the network interface comes back up, Port-1 is reenabled and its control leads are reasserted. The LMI state on Port-1 has no effect on the LMI state on the network interface. That is, Port-1’s LMI follows the network interface’s LMI. This setting is useful if the router connected to Port-1 is used to initiate recovery when network failures are detected.

Port-2_Follows_Net1-FR1 – Reacts like the Port-1_Follows_Net1-FR1 selection, but for Port-2 instead.

Rtr-S0_Follows_Net1-FR1 – Brings LMI down on Rtr-S0 when LMI on the network interface goes down, disabling Rtr-S0. When LMI on the network interface comes back up, Rtr-S0 is reenabled. The LMI state on Rtr-S0 has no effect on the LMI state on the network interface. That is, Rtr-S0’s LMI follows the network interface’s LMI.

All_Ports_Follow_Net1-FR1 – Brings LMI down on all user data ports when LMI on the network interface goes down, disabling all ports and deasserting their control leads. Allows LMI to come back up and reenables the ports when LMI comes up on the network. That is, LMI on each port follows the network interface’s LMI. The state of LMI on the port will not affect the state of LMI on the network interface.

Port-1_Codependent_with_Net1-FR1 – Brings LMI down on the network interface when LMI on Port-1 goes down (or LMI down on Port-1 when LMI on the network interface goes down), and allows LMI to come back up when LMI comes back on the other interface. That is, the LMI state for one interface is dependent on the other. Use this setting when backup is through the router instead of the unit. It is not recommended since it makes fault isolation more difficult.

Port-2_Codependent_with_Net1-FR1 – Reacts like the Port-1_Codependent_with_Net1-FR1 selection, but for Port-2 instead. The state of LMI on the network interface will not affect the state of LMI on Port-1.

Rtr-S0_Codependent_with_Net1-FR1 – Brings LMI down on the network interface when LMI on Rtr-S0 goes down (or LMI down on Rtr-S0 when LMI on the network interface goes down), and allows LMI to come back up when LMI comes back on the other interface. That is, the LMI state for one interface is dependent on the other.

LMI Behavior (9783 and 9788)

Possible Settings: Independent, Net1-FR1_Follows_Port-1, Port-1_Follows_Net1-FR1, Port-1_Codependent_with_Net1-FR1

Default Setting: Port-1_Codependent_with_Net1-FR1

For units that support ATM, configures the state of LMI on Port-1 and the state of the ATM link on the network interface to be passed from one interface to another.

Independent – Handles the state of each interface separately so that the LMI state of Port-1 has no effect on the state of the ATM link on the network interface, and vice versa.

Net1-FR1_Follows_Port-1 – Brings down VCs cross-connected to Port-1 on the network interface when LMI on Port-1 goes down, and sends F5 OAM cells on all network VCs cross-connected to Port-1 DLCIs to alert the network and far-end device that frame relay data can not be delivered through the device. When LMI on Port-1 comes back up, the network VCs are also re-enabled. This setting is useful at a central site when the remote site router on the other end of the PVC connection can initiate recovery via a redundant central site when there is a catastrophic central site LAN or router failure. Not recommended for NSPs.

Port-1_Follows_Net1-FR1 – Brings down LMI on Port-1 when there is a physical failure or ATM failure on the network interface. When the alarm on the network interface is cleared, Port-1 is re-enabled and its control leads are reasserted. This setting is useful if the router connected to Port-1 is used to initiate recovery when network failures are detected.

Port-1_Codependent_with_Net1-FR1 – The LMI state for Port 1 and the Net1-FR1 interface are dependent on each other. If the LMI is down on either interface, the system will bring the LMI down on the other interface. When the LMI is up on either interface, the system will bring the LMI up on the other interface. When Port-1 LMI goes down, in addition to bringing down the internal network frame relay link, the unit also sends F5 OAM cells on all network VCs cross-connected to Port-1 DLCIs to alert the network and far-end device that frame relay data can not be delivered through the device. Use this setting when backup is through the router instead of the unit. Note that when the router is disconnected, the NSP cannot access the unit using multiplexed VCs.

DDS Network Interface

FrameSaver Models 9623 and 9626 have a DDS network interface.

Table 3-9. DDS Network Physical Interface Options (1 of 2)

Transmit Timing

Possible Settings: Internal, Receive Default Setting: Receive

Specifies the unit’s timing source based upon how the unit will be used. When the unit is connected to a DDS (Digital Data Service) network for standard operation, timing is provided by the network. In a LADS, or LDM, application (local area data set/limited distance modem), where local and remote FrameSaver units are directly connected, one of the units provides timing for both units.

Internal – Timing for the unit and its attached LADS partner is derived from the unit’s internal clock. Use this setting when the unit will be used as a LADS primary timing unit, where the FrameSaver unit establishes overall timing for the two interconnected units.

Receive – Timing for the unit is derived from the network Received signal. Use this setting for standard DDS operation, or when the unit will be used as a LADS secondary timing unit. See DDS Line Rate (Kbps).

3. Configuration Options

DDS Line Rate

Possible Settings: Auto_On_No_Signal, Initialize_From_Network, 56, 64CC Default Setting: Auto_On_No_Signal

Configures the network interface’s line speed to match the Digital Data Service’s (DDS’s) line speed. This is the rate at which data is transmitted over the DDS line.

Display Conditions – This option only appears when Transmit Timing is set to Receive.

Auto_On_No_Signal – Automatically detects the line rate on the network interface whenever a No Signal alarm is declared, the unit is reset, or the line rate is changed to Auto_On_No_Signal and saved, then changes the unit’s operating rate to match the network’s. It may take up to 15 seconds each time automatic rate detection and adjustment occurs.

Initialize_From_Network – Automatically detects the line rate on the network interface once, then changes the unit’s operating rate to match the network’s. Automatic rate detection and adjustment, or Autobaud, will not occur again unless the line rate is changed to Initialize_From_Network or Auto_On_No_Signal and saved. It may take up to 15 seconds for automatic rate detection and adjustment to occur.

56 – Forces the line rate to 56 Kbps.

64CC – Forces the line rate to 64 Kbps Clear Channel (72 Kbps on the line).

V.54_&_ANSI – DCLB-actuate and DCLB-release sequences that comply with either V.54

or ANSI T1.403, Annex B standard will be recognized and will control initiation and termination of a DCLB for this frame relay link. The actuate and release sequences do not need to match (for example, a DCLB started with a V.54 actuate sequence can be stopped with an FT1 release sequence).

DSU Latching Loopback

Possible Settings: Enable, Disable Default Setting: Enable

Specifies whether the FrameSaver unit responds to the DSU Latching Loopback sequence sent by the network, as specified by TR62310.

Enable – Responds to DSU latching loopback commands. The unit remains in loopback until the network receives the loopback release sequence.

Disable – Does not respond to the DSU loopback commands, or terminates the latching loopback test if it is active.

NOTE: Because the latching loopback code is a control sequence, as opposed to a bipolar violation sequence, user data may activate the loopback. Disable this option to stop an unintentional latching loopback.

Require DSU Latching Loopback Preamble

Possible Settings: Enable, Disable Default Setting: Disable

Specifies whether the FrameSaver unit requires the ANSI or FRF proposed preamble for the network-initiated DSU Latching Loopback when detecting the loopback sequence.

Display Conditions – This option only applies when the unit is operating on a standard DDS 64KCC circuit and DSU Latching Loopback (64KCC) is enabled.

NOTE: To prevent confusion, do not use the following link names: Network, Net1-FR1, Port-1, or Port-2. These names will be treated as nonunique and the Link Name Not Unique message appears and you must enter another name.

HQ_Site – The link name configured in the remote site unit (originating a backup call) for the central site unit (answering a backup call). One link has a default value of HQ_Site to allow for Automatic Backup Configuration.

Link Status

Possible Settings: Auto, Disable Default Setting: Auto

Determines whether the ISDN frame relay link is in or out of service.

Auto – The link is configured to be in service when needed. Packets will be transmitted and received on the interface, and the LMI for a PVC connection will become active when the link is required. If this profile is configured as the alternate link and the primary link or DLCI fails, the unit dials the Outbound Phone Number, or the Alternate Outbound Phone Number if the first call was unsuccessful. The unit also answers calls from Inbound Call IDs associated with this link. This link profile becomes active when:

This profile is configured as the alternate link and there is a failure of a primary link or DLCI.

Source or Primary Destination DLCIs are configured on this link.

When the primary link recovers, the call is automatically disconnected.

Disable – The frame relay link is out of service. No data will be transmitted or received on the interface. If there is are any active calls when disabled, the calls are ended and no calls will be answered or originated using this profile.

Outbound Phone Number

Possible Settings: 0 – 9, *, #, space, _ , –, (, or ) Default Setting: none

Specifies the primary phone number to call (the ISDN Called Party Identifier) for the Link Profile. Up to 18 valid characters can be entered. Each Outbound Phone Number must be unique. If not, the Outbound Phone Number is Not Unique message appears and you must enter another phone number.

NOTE: For every originating (outbound) phone number entered, an answering (inbound) phone number must be entered at the far end, and vice versa.

Currently active calls are not effected when this number is changed.

Inbound Calling ID 1 or 2

Possible Settings: 0 – 9 Default Setting: none

Specifies the local phone number of a remote device from which that the unit will accept calls (the ISDN Calling Party Identifier). Up to 18 digits can be entered. Each Inbound Calling ID must be unique. If not, the Inbound Calling ID n is Not Unique message appears and you must enter another phone number.

For remote devices with a PRI DBM, only one Inbound Calling ID is required. Inbound Calling ID 2 is provided to identify incoming calls from a second phone number assigned to a remote device with a BRI DBM.

NOTES:

– Inbound Calling ID 2 is only useful when multiple local phone numbers are

programmed at the originating site (e.g., a 2B+D BRI location).

– For every originating (outbound) phone number entered, an answering (inbound)

phone number must be entered at the far end, and vice versa.

Currently active calls are not effected when this number is changed.

0 – 9 – Specifies the numbers in the remote device’s local phone number.

Maximum Link Rate (Kbps)

Possible Settings:

For a BRI DBM: 64, 128 For a PRI DBM: 64 – 1472

Default Setting: 64

Specifies the maximum rate that will be attempted for the frame relay link when it is activated. The actual rate achieved on the link depends upon the number of successful calls placed or answered, and the negotiated rate on each call.

NOTE: This option takes effect as soon as a change is saved. If the rate is increased, additional calls will be placed. If the rate is decreased, calls will be dropped. For extra calls to be successful, the Maximum Link Rate must be increased at the originating device before it is increased at the answering device.

64 – An individual frame relay link is formed and a single call is placed using a B-channel when the link is activated.

128 . . . 1472 – A constituent link is configured for each multiple of 64 Kbps in the specified bandwidth. This bundle of constituent links will function as a single frame relay multilink. When the multilink aggregate link is activated, calls will be placed or answered on as many constituent links as possible based upon available B-channels.

Caller ID – Incoming calls will only be answered and the frame relay link on this Link Profile will only be activated when the Caller ID received from the switch matches one of the configured Inbound Calling IDs.

Proprietary – Incoming calls will always be answered, even when no Caller ID is provided by the switch, provided the following conditions are met:

Link Status is set to Auto (the default).

At least one ISDN Link Profile is enabled.

When using the Proprietary method, the unit queries the originating unit for its Local Phone Number. If the returned phone number matches one of the configured Inbound Calling IDs, the call is accepted. If the queried unit does not respond with its phone number within five seconds, the unit drops the call.

Alternate Outbound Phone Number

Possible Settings: 0 – 9, *, #, space, _ , –, (, or ) Default Setting: none

Specifies an alternate phone number to call (the ISDN Called Party Identifier) when a call using the primary Outbound Phone Number was unsuccessful. Up to 18 valid characters can be entered. Each Outbound Phone Number must be unique. If not, the Alt Outbound Phone Number is Not Unique message appears and you must enter another phone number.

Assigning Time Slots/Cross Connections

The Time Slot Assignment/Cross Connect feature provides an easy method of assigning time slots for frame relay data and creating cross-connections to the synchronous data interface. The system allows you to assign DS0s on the T1 network interface and between the user data port and network interface in order to share the T1 network.

You can also clear cross-connection assignments for the system, or for a selected slot or interface.

NOTE:

Although it is not required, it is suggested that you progress through each screen in order, from top to bottom.

Assigning Time Slots to the Network Interface

Before assigning network time slots for use by frame relay traffic, configure the Network physical and Frame Relay options (if needed), then allow Time Slot Discovery to autodetect and assign the appropriate time slots to frame relay.

If there are multiple Frame Relay data links on the network interface, or if Time Slot Discovery is not currently active, you can manually assign time slots on the network interface for frame relay traffic using the Frame Relay Network Assignments screen. This screen is read-only when Time Slot Discovery is set to Enable for the network interface.

Only those DSX-1-to-Network assignments from page 1 are displayed on this page, from left to right and top to bottom in ascending order, by network and time slot.

When a CGA condition (LOS, OOF, or AIS) is declared for a T1 interface, the signaling bits being transmitted to the other T1 interface for the DS0 are forced to idle for two seconds (except for user-defined patterns which are transmitted immediately). This drops any call in progress. The signaling bits are then forced to the selected state (Busy or Idle), and remain in this state until the CGA condition clears. At this point, the received signaling bits from the T1 interface which formerly had the CGA condition are passed through to the other T1 interface.

NOTE:

Trunk conditioning will only occur on DS0s that are cross-connected to another T1 interface. All other DS0s remain unaffected by trunk conditioning.

Enter one of the values shown in Table 3-23, Signaling and Trunk Conditioning

Values, in each of the fields on both the Network side and the DSX-1 side.

Although you can choose any value for the DSX-1 side, the default value displayed is based on a typical setting that would be used with the corresponding Network side value. Typical pairs of values are shown in the table below. If you change the Network side value, the DSX side value is changed to the corresponding default value.

Default Setting:

For a user data port link: Initialize_From_Interface For a network link: Auto_On_LMI_Fail

Specifies either the LMI protocol supported on the frame relay interface or the discovery source for the LMI protocol.

Initialize_From_Net1FR1 – The LMI type supported on this frame relay link will be configured to match the LMI protocol initially discovered on the primary Network frame relay link (Net1FR1). LMI Protocol is set to None internally, but once a protocol has become active or is set on the primary Network link, the protocol will be set to the same value on this link (Standard, Annex-A or Annex-D). The protocol will not be updated based on changes to Net1FR1 after being set initially.

Display Conditions – This option value only appears for a user data port.

Initialize_From_Interface – The LMI type supported on this frame relay link will be configured to match the LMI protocol discovered from the attached Network line or DTE device. Once a protocol has become active, the protocol will be set to the protocol discovered (Standard, Annex-A or Annex-D) on the frame relay link. The protocol will not be updated after being initially discovered. Frame relay links on user data ports discover the LMI protocol from an attached device via LMI status polls. Frame relay links on the network interface discover LMI protocol by sending polls to an attached Network line and “listening” for correct poll response messages.

Auto_On_LMI_Fail – The LMI type supported on this frame relay link will be configured to match the LMI protocol discovered from the attached Network line or the DTE device whenever an LMI Link Down failure occurs. This option is available for frame relay links on the Port and network interfaces. Frame relay links on user data ports discover the LMI protocol from LMI status polls by attached DTE devices. Frame relay links on the network interface discover LMI protocol by sending polls to an attached Network line and “listening” for correct poll response messages.

Standard – Supports Standard LMI and the Stratacom enhancements to the Standard LMI.

Annex-A – Supports LMI as specified by Q.933, Annex A.

Manually Configuring DLCI Records

The Auto-Configuration feature automatically configures DLCI Records and their PVC Connections. DLCI Records can also be created manually (see Table 3-26,

DLCI Record Options).

Main Menu

→ Configuration → [Network/Data Port/ISDN/Virtual Router Ports]

→ DLCI Records

Available paths to DLCI Records Options depend on the Service Type and FrameSaver model:

n DLCI Records is not an option on the Network menu unless Service Type is

Frame Relay

n Data Port is available only on CSU/DSUs

n ISDN is available only when the FrameSaver unit has an ISDN DBM installed

n Virtual Router Ports is available only on the FrameSaver SLV Router

Typically, DLCI Records only need to be configured when building Management PVCs between the NOC and the central site unit; the unit automatically configures non-management DLCI Records and PVC Connections.

Table 3-26. DLCI Record Options (1 of 4)

DLCI Number

Possible Settings: 16 – 1007 Default Setting: Initially blank; no default.

Specifies the number for the DLCI in the DLCI record. The parameter determines which DLCI record is used for transferring data on a particular frame relay interface. DLCI numbers range from 0to1023. However, the numbers 0 – 15 and 1008 – 1023 are reserved. Entry of an invalid number results in the error message Value Out of Range (16–1007). If the DLCI number is part of a connection, this field is read-only.

NOTES:

– If a DLCI number is not entered, the DLCI record is not created.

– The DLCI number entered must be unique for the interface.

– Changing settings for this configuration option causes the FrameSaver unit to abort

any active frame relay tests.

16 – 1007 – Specifies the DLCI number (inclusive).

DLCI Type

Possible Settings: Standard, Multiplexed, IP Enabled Default Setting:

For user data port DLCIs: Standard For network interface DLCIs: Multiplexed

Specifies whether the DLCI is standard or multiplexed. This field is read-only when the selected DLCI is used in a PVC or Management link connection and the DLCI Type is Standard.

Display Conditions – This option does not appear for a user data port or a virtual router port, and it cannot be changed if the DLCI is specified as the TS Access Management Link.

Standard – Supports standard DLCIs as specified by the Frame Relay Standards. Use this setting when a non-FrameSaver unit is at the other end.

Multiplexed – Enables multiplexing of multiple connections into a single DLCI. Allows a single PVC through the frame relay network to carry multiple DLCIs as long as these connections are between the same two endpoints (proprietary). Do not select Multiplexed unless there are FrameSaver units at both ends of the connection.

IP Enabled – Enables connection to one or more endpoints through a Layer 3 network. A Payload Management PVC is created as well as the IP Enabled DLCI.

DLCI Priority

Possible Settings: Low, Medium, High Default Setting: High

Specifies the relative priority for data received on the DLCI from an attached device (also known as quality of service). All data on Port 1 is cut-through, as long as there is no higher-priority data queued from another user port. The DLCI priority set for an interface applies to data coming into that interface. For example, the priority set for DLCIs on Port 1 applies to data coming into Port 1 from the attached equipment (such as a router).

NOTE: For units with multiple user data ports, since pipelining occurs on Port-1, it is recommended that higher priority data be connected to Port-1 .

Display Conditions – This option is not available for the network interface or, if the model has ISDN backup capability, an ISDN DBM interface.

Low – Data configured for the DLCI has low priority.

Medium – Data configured for the DLCI has medium priority.

High – Data configured for the DLCI has high priority.

Outbound Management Priority

Possible Settings: Low, Medium, High Default Setting: Medium

Specifies the relative priority for management traffic sent on management PVCs on this DLCI to the network.

Display Conditions – This option is not available on a user data port or a virtual router port.

Low – Management data configured for the DLCI has low priority.

Medium – Management data configured for the DLCI has medium priority.

High – Management data configured for the DLCI has high priority.

Backup Group

Possible Settings: A, B, C, . . . Z, None Default Setting: None

Assigns DLCIs to a backup group so backup does not take place unless all DLCIs in the group are no longer operational or latency has been exceeded. Backup is terminated when one DLCI in the group is operational again. This feature reduces backup charges when redundant PVCs have been configured.

Display Conditions – This option is not available on a user data port, a virtual router port, or an ISDN DBM interface.

A – Z – Specifies the designation for this group of DLCIs. Only DLCIs in a PVC will be considered part of a Backup Group.

None – No Backup Groups have been set up.
