Chapter 1 - Network Installation
Octal T1-10/100 RIOP Front Panel
This section of the manual will help you install the Octal T1-10/100 RIOP to connect a local
Ethernet and up to eight remote corporate networks. These connections can be made to other
Compatible Systems devices or internetworking equipment from other vendors.
In summary, the steps for installation are:
1. After mounting the router or placing on a desktop, make sure it is not connected to
any power source.
2. Connect the router to the Ethernet network.
3. Connect the router to the T1 transmission equipment.
4. Connect a management console to the router (optional).
5. Plug in the power cable and power up the router.
Connecting the Octal T1-10/100 to the Ethernet
The 10/100 Ethernet interface direc tly supp orts 1 00B as eTx or 10B as eT twisted-pair Ether net.
To connect the router’s Ethernet interface to twisted-pair Ethernet cabling, you will need an
unshielded twisted-pair station cable that is already connected
twisted-pair hub (for a transmit speed of 10 Mbps) or a 100Mbps Fast Ethernet hub (for a
transmit speed of 100 Mbps).
v
Note: Ethernet cables and cable conn ectors ar e not suppl ied with the O ctal T1-10/ 100 RIOP
product. C ategory 5 ca bling is requir ed for 100 BaseT oper ation. Pl ease contact yo ur r esel ler
or your Compatible Systems representative for information on obtaining the correct Ethernet
cabling supplies.
To connect the router to the twisted-pair network, simply plug the twisted-pair cable into the
RJ-45 Ethernet connector on the front of the unit.
Connecting the Octal T1-10/100 to a T1 Line
T o conn ect each T1 por t to a T1 line, you need an 8- pin connecto r jumper cab le (four wires are
used). The jumper cable should already be connected to th e RJ-45 jack which was in stalled by
your telephone company.
Plug one of the supplied DB-26 male to Quad RJ-45 cables into the DB-26 T1 female
connector on the front of the device. Make sure that the jack screws on the DB-26 connector
are secured. Then plug the jumper cable into one of the RJ-45 T1 connectors on the Quad RJ45 cable.
v
Note: Port numbers 0 - 3 are stamped on each T1 RJ-45 connector. For ports 4 -7, the
connector marked “Port 0” is Port 4, the connector marked “Port 1” is Port 5, etc.

Chapter 1 - Network Installation 3
v Note: The Octal T1-10/100 RIOP includes loopback features which can be used to check
the functionality of your T1 lines. Before attempting to route network traffic, use these features
to check each line’s basic integrity.
Connecting a Management Console
If you wish to connect an out-of-band management console, use the supplied DB-25 male to
DB-25 female console cable and connect to the Console interface on the Octal T1-10/100
RIOP. You can use a dumb terminal or a computer equipped with VT100 terminal emulation.
The default settings for the Console interface are VT100 terminal emulation, 9600 bps, 8 bits,
no parity, 1 stop bit and no Flow Control.
v
Note: The Octal T1-10/100 RIOP also has an AUX interface. This is a modem connection
which should only be used in consultation with Compatible Systems Technical Support staff,
who will provide instruction on its use.
Powering Up the Router
Connect the supplied power cord to the front of the VSR and set the power switch to “On.” At
power-up, the router will take approximately one minute to become visible to CompatiView.
v
Note: If you want to use Telnet as a management method, you must first configure an IP
address int o the router with either an ou t-of -ba nd con so le , Compa tiView, or a reconfigured IP
host or workstation on the same Ethernet segment as the router. See the appropriate VSR
chassis section of the manual for more information on Command Line Management.
Chapter 2 - Quickstart Instructions 4
Chapter 2 - Quickstart Instructions
This Quickstart chapter briefly discusses the major parameters that must be set in order to use
the Octal T1-10/100 RIOP as part of your VSR multigigabit switching router.
Detailed information on the meaning of the router’s parameters is provided in the Compa-
tiView Management Software Reference Guide and the Text-Based Configuration and
Command Line Management Reference Guide. You should use this list as a starting point to
look up more specific information in the other documents.
If you need more general information on IP, IPX, AppleTalk or wide area protocols, see the
Appendices in the CompatiView Management Software Reference Guide.
There are a number of parameter settings which are optional, in the sense that they are not
required for all installations. These settings are not covered in this chapter.
In this chapter:
CV = CompatiView
TB = Text-Based Configuration
In order to successfully connect to an Internet Service Provider (ISP), you must use router
configuration parameters which will be provided by the technical staff of the ISP. These
parameters must include all IP addresses, WAN settings and any applicable authorization
routines. Please check with your ISP before changing the configuration of your Octal T1-10/
100 RIOP.
v
Note: This Quickstart does not include information on setting up packet filters for using the
router as a Firewall. Se e the CompatiView Management Software Reference Guide or Text-
Based Configuration and Command Line Management Reference Guide regarding IP
packet filters for more information.
Ethernet Interface Confi guration
Ethernet interfaces are considerably easier to set up than wide area interfaces since there are
fewer choices that need to be made regarding communications protocols and parameters. We
recommend that you begin by configuring any Ethernet interf ace parameters before proceeding
to configure WAN interface parameters.
IP Protocol
Required for IP
These parameters set the basic address characteristics of the interface. They provide enough
information for another IP node to find the interface (such as a Telnet client), but not enough
information for routing to take place.
• IP address
• IP subnet mask
• IP broadcast address
CV: Use the TCP/IP Routing: Ethernet 0 Dialog Box to set these parameters.
TB: Use the configure command and set the IPAddress, SubnetMask, and IPBroadcast
keywords in the IP Ethernet 0 section.
Suggested for IP
These parameters help supply information a bout the segment that the interface is connected to.
With this information, routing can take place.
• Set IP RIP 1, IP RIP 2 or OSPF (Open Shortest Path First)
IPX Protocol
Chapter 2 - Quickstart Instructions 5
• IP static routes
CV: Use the TCP/IP Routing: Ethernet 0 Dialog Box to set RIP, and the IP Static Routing
Dialog Box (under Global/IP Static Routes) to set static routes. OSPF can only be configured
using text-based configuration.
TB: Use configure and set either the RIPVersion keyword or the OSPFEnabled keyword for
the IP Ethernet 0 section. Use edit config and add static routes in the IP Static section.
Required for IPX
Generally, there are no required changes from the shipping Ethernet configuration for IPX.
The Ethernet interface will autoconfigure to use the two most common IPX frame types, and
will adapt to conditions on the Ethernet.
Suggested for IPX
You may want to s et yo ur ow n n etwo rk n umb ers , rat her t han using the autoconfigured val ues.
You may also want to turn off unused frame types.
CV: Use the IPX Routing: Ethernet 0 Dialog Box.
TB: Use configure and set keywords in the IPX Ethernet 0 section.
AppleTalk Protocol
Required for AppleTalk
Generally, there are no required changes from the shipping Ethernet configuration for AppleTalk. The Ethernet interface will autoconfigure to use AppleTalk Phase 2, and will adapt to
conditions on the Ethernet.
Suggested for AppleTalk
You may want to s et yo ur ow n n etwo rk n umb ers , rat her t han using the autoconfigured val ues.
You may also want to use more meaningful zone names.
CV: Use the AppleTalk Routing: Ethernet 0 Dialog Box.
TB: Use configure and set keywords in the AppleTalk Phase 2 Ethernet 0 section.
DECnet Protocol
Required for DECnet
The router’s shipping configuration does not have DECnet turned on. In order to be used,
DECnet must be turned on both globally and for a particular port.
• Set DECnet on (globally, and for this port)
• Set DECnet area
• Set DECnet node
CV: Use the DECnet Routing Dialog Box (under Global/DECne t Routing) and the DECnet:
Ethernet 0 Dialog Box.
TB: Use configure and set the Mode keyword in the DECnet Ethernet 0 section. Use
configure and set the Enabled, Area, and Node keywords in the DECnet Global section.
v
Note: Setting DECnet on for any port with the command line also sets DECnet on globally.
In CompatiView you must set a global parameter and a port-specific parameter.
Suggested for DECnet
Setting the parameters above should be adequate for most installations.
Chapter 2 - Quickstart Instructions 6
WAN Interface Configuration
The default setting for all WAN interfaces on your Octal T1-10/100 RIOP is Off for all protocols and for the link configuration. In order to use a WAN interface, you may first need to set
some physical parameters and then set up the link and protocol parameters.
T1 Physical Communications Settings
Required for Dedicated Line Operation
No changes from the default values are required for standard operation over a T1 line. The
default values are listed in Chapter 3.
Suggested for Dedicated Line Operation
Changing to fractional T1, different coding or framing, etc., may be required for a particular
installation.
CV: Use the Physical Configuration: WAN Dialog Box.
TB: Use configure and the T1 Interface WAN 0 (and/or any other port you wish to con figure)
section.
PPP Configuration
This section covers the settings required for PPP (point-to-point) protocol operation of the T1
WAN interfaces.
WAN Link Configuration
Required for Dedicated Line Operation
This is the only mode of operation supported via the built-in T1 CSU/DSU.
• Set PPP connection
CV: Use the Link Configuration: WAN Dialog Box.
TB: Use configure and then set the Mode keyword in the Link Config WAN 0 (and/or any
other port you wish to configure) section.
Suggested for Dedicated Line Operation
Dedicated line operation generally does not require additional parameters for operation.
IP Protocol
Required for IP
WAN interfaces which are set for PPP operation do not generally use an IP address. They are
set to act as an “unnumbered interface.” In this mode of operation, there are no required
settings.
Suggested for IP
These parameters help supply information a bout the segment that the interface is connected to.
With this information, routing can take place.
• Set IP RIP 1, IP RIP 2, OSPF (Open Shortest Path First) or BGP (Border Gateway
Protocol)
• Set IP static routes
CV: Use the TCP/IP Routing: WAN Dialog Box to set RIP, and the IP Static Routing Dialog
Box (under Global/IP Static Routes) to set static routes. OSPF and BGP can only be configured using text-based configuration.
TB: Use configure and set either the RIPVersion keyword or th e OSPFEnabled keyword in
the IP WAN 0 (and/or any other port you wish to configure) section. Add static routes and a
default router using the edit config IP Static command.
v
Note: Due to the complexity of BGP, configuration parameters for BGP are not given in this
Quickstart. For help with BGP configuration parameters, and other configuration questions,
refer to the Tech Support pages on the Compatib le Systems Web site at:
http://www.compatible.com/.
IPX Protocol
Required for IPX
WAN interfaces which are set for PPP operation do not generally use an IPX address. They are
set to act as an “unnumbered interface.” In this mode of operation, there are no required
settings.
AppleTalk Protocol
Required for AppleTalk

DECnet Protocol
Required for DECnet
The router’s shipping configuration does not have DECnet turned on. In order to be used,
DECnet must be turned on both globally and for a particular port.
• Set DECnet on (globally, and for a port)
• Set DECnet area
• Set DECnet node
CV: Use the DECnet Routing Dialog Box (under Global/DECne t Routing) and the DECnet:
WAN Dialog Box.
TB: Use configure and set the Mode keyword in the DECnet WAN 0 (and/or any other port
you wish to configure) section. Use configure and set the Enabled, Area, and Node keywords
in the DECnet Global section.
v
Note: Setting DECnet on for any port with the command line also sets DECnet on globally.
In CompatiView you must set a global parameter and a port-specific parameter.
Suggested for DECnet
Setting the parameters above should be adequate for most installations.
Frame Relay Configuration
This section covers the settings required for Frame Relay operation of the T1 WAN interfaces.
WAN Link Configuration
Required for Dedicated Line Operation
This is the only mode of operation supported via the built-in T1 CSU/DSU.
• Set Dedicated connection
• Set Frame Relay connection
CV: Use the Link Configuration: WAN Dialog Box.
Chapter 2 - Quickstart Instructions 8
TB: Use configure and then set the Mode and ConnectMode keywords in the Link Config
WAN 0 (and/or any other port you wish to configure) section.
Suggested for Dedicated Line Operation
Dedicated line operation generally does not require additional parameters for operation.
Frame Relay DLCI Mappings
If you are connecting to another Compatible Systems router, this information is not required
for Frame Relay operation. Compatible Systems uses IARP (Inverse Address Resolution
Protocol) to dynamically generate this information. To connect to other vendors’ routers
which do not support IARP, you must provide DLCI-to-protocol mapping information.
v
Note: Many Internet Service Providers (ISP’s) do not support IARP as a default. If your
WAN interface will be connected to an ISP via Frame Relay, check with your ISP technical
staff on whether or not you must manually enter DLCI information.
CV: Use the DLCI Mapping Database Dialog Box (under WAN/Link Configuration/DLCI
button).
TB: Use configure and set the DLCI keyword in the Frame Relay WAN 0 (and/or any o ther
port you wish to configure) section.
IP Protocol
There are two ways to set up Frame Relay. One is to set the WAN interface as a “numbered
interface.” This means that the interface (and thus the Frame Relay network) will have an IP
address, subnet mask, etc. The other is to set it as an unnumbered interface and specify that the
link is point-to-point Frame Relay and set the local DLCI. Unnumbered Frame Relay can only
be configured using text-based configuration. Instructions are provided for both options.
Required for IP Numbered Interface
• IP numbered interface
• IP address
• IP subnet mask
• IP broadcast address
CV: Use the TCP/IP Routing: WAN Dialog Box.
TB: Use the configure command and the Numbered, IPAddress, SubnetMask, and
IPBroadcast keywords in the IP WAN 0 (and/or any other port you wish to configure)
section.
Required for IP Unnumbered Interface
• IP unnumbered interface
• Point-to-Point Frame Relay
• Local DLCI
TB: Use the configure command and the Numbered, PointToPointFrame, and InterfaceDLCI keywords in the IP WAN 0 (and/or any other port you wish to configure) section.
Suggested for IP
These parameters help supply information a bout the segment that the interface is connected to.
With this information, routing can take place.
• Set IP RIP 1, IP RIP 2, OSPF (Open Shortest Path First) or BGP (Border Gateway
Protocol)
• IP static routes
CV: Use the TCP/IP Routing: WAN Dialog Box to set RIP, and the IP Static Routing Dialog

Note: Due to the complexity of BGP, configuration parameters for BGP are not given in this
Quickstart. For help with BGP configuration parameters, and other configuration questions,
refer to the Tech Support pages on the Compatib le Systems Web site at:
http://www.compatible.com/.
Required for IPX
Frame Relay operation requires that the WAN interface be set as a “numbered interface.” This
means that the interface (and thus the Frame Relay network) must have an IPX network
number.
• IPX numbered interface
• IPX network number
CV: Use the IPX Routing: WAN Dialog Box.
TB: Use configure and set the Numbered and Net keywords in the IPX WAN 0 (and/or any
other port you wish to configure) section.
Suggested for IPX
The settings above are all that is generally required for IPX operation over Frame Relay.
AppleTalk Protocol
Required for AppleTalk
Frame Relay operation requires that the WAN interface be set as a “numbered interface.” This
means that the interface (and thus the Frame Relay network) must have an AppleTalk network
number and the interface must have an AppleTalk node number.
• AppleTalk numbered interface
• AppleTalk network number
• AppleTalk node numbe r
• AppleTalk zone name
CV: Use the AppleTalk Routing: WAN Dialog Box.
TB: Use configure and set the Numbered, NetLower, and DefZone keywords in the Apple-
Talk WAN 0 (and/or any other port you wish to configure) section.

Required for DECnet
In order to be used, DECnet must be turned on both globally and for a particular port.
WAN interfaces which are set for Frame Relay operation do not need any additional parameters set in order to function.
• Set DECnet on (globally, and for this port)
CV: Use the DECnet Routing Dialog Box (under Global/DECne t Routing) and the DECnet:
WAN Dialog Box.
TB: Use configure and set the Mode keyword in the DECnet WAN 0 (and/or any other port
you wish to configure) section.
v
Note: Setting DECnet on for any port with the command line also sets DECnet on globally.
In CompatiView you must set a global parameter and a port-specific parameter.
SMDS Configuration
This section covers the settings required for SMDS (Switched Multi-megabit Data Service)
operation of the T1 WAN interfaces (IP only). SMDS is a connectionless, packet-switched
service that offers LAN-to-LAN connectivity across a wide area at up to 1.544 Mbps. SMDS
addresses and other parameters can only be set using the command line interface.
v
Note: The IP protocol settings and the physical communication settings are the same as they
would be for Frame Relay operation. The only parameters which sh ould be set differently for
SMDS are the Link Configuration and the SMDS addressing section.
Chapter 2 - Quickstart Instructions 10
WAN Link Configuration
SMDS is presently supported in the Octal T1-10/100 RIOP only via synchronous dedicated
line operation.
• Set Dedicated connection
