Chapter 1 - Introduction
About the BR Router
Congratulations on your purchase of the BR Router multiport wide area router. The
BR Router supports the IP, IPX, AppleTalk, and DECnet network protocols, with
dial-on-demand and leased-line operation using the PPP and/or the Frame Relay
wide area protocols.
A Note About On-Demand Internetworking
The BR Router can be configured to provide cost effective on-demand connections
over a wide area communications link (typically a voice phone line, a switched 56
line, or an ISDN line). Your network traffic and the configuration you place in the
router will determine how often and for how long such a link is connected.
THE SHIPPING CONFIGURATION IN YOUR BR ROUTER DOES NOT
PROVIDE AUTOMATIC ON-DEMAND INTERNETWORKING. YOU MUST
FIRST PROGRAM YOUR ROUTER TO WORK IN THIS ROLE ON YOUR
NETWORK.
YOU SHOULD CAREFULLY MONITOR PHONE LINE USAGE TO BE SURE
THAT YOUR ROUTER CONFIGURATION IS ALLOWING THE ROUTER TO
DROP THE COMMUNICATIONS LINK WHEN IT ISN’T NEEDED.
BR Router Installation Overview
This manual will help you install the BR Router to connect a local Ethernet to 1 or
2 remote networks and/or remote PPP client computers. These connections can be
made to other DCB routers, routers from other vendors, or PPP compliant dial-in
software packages running on a variety of computers. The wide-area interfaces on
the BR Router may be used to interconnect your network with other corporate
networks, and to make your network’s resources available to dial-in clients.
8
In short, the installation steps are:
1. Install the BR Router hardware and connect it to one or more line
communication devices (including modems, 56K CSU/DSU’s, ISDN Terminal
Adapters, and fractional or full T1 CSU/DSU’s).
2. Select the management method you wish to use with the router. If you want to
use the RouterView management software, you must install the software on a
Windows PC or Macintosh computer which is connected to your network.
3. Configure the BR Router LAN and WAN parameters using the management
method you have chosen.
If you have any difficulties during the installation or use of the BR Router that are
not answered by this guide, please call Data Comm for Business or your BR Router
reseller. DCB’s phone number is listed on the front of this guide. We will be happy
to help you.
The manual is divided into several sections that should provide you with all the

Needed For Installation
Before connecting the BR Router to your network, you need to make sure that you
have the necessary equipment for connecting to the local Ethernet and the wide area
transmission device(s) (modem, 56K CSU/DSU, ISDN terminal adapter, T1
CSU/DSU).
Ethernet Connection Requirements
The BR Router’s Ethernet interface directly supports 10BaseT twisted-pair
Ethernet. Other Ethernet cabling types (such as thin Ethernet, thick Ethernet, fiber
optic cabling or pre-10BaseT twisted-pair) can be supported using a 10BaseT mini-
hub or other conversion device.
10Base-T Twisted-Pair Ethernet
To connect the router’s Ethernet interface to twisted-pair Ethernet cabling you will
need an unshielded twisted-pair station cable that is connected to a 10BaseT-
compatible twisted-pair hub.
v Note: Ethernet cables and cable connectors are not supplied with the BR Router
product. Please contact your reseller or your DCB representative for information
on obtaining the correct Ethernet cabling supplies.
Telco Line Connection Requirements
The BR Router is not a line communications device. In order to connect to a wide
area transmission line, you must use a modem, 56K CSU/DSU, ISDN Terminal
11
Adapter, or T1 CSU/DSU. Which of these devices you use depends on the type of
telco line you are connecting one of the router’s wide area interfaces to.
v Note: Before attempting to connect the BR Router to a leased telco line, use the
loopback features of your CSU/DSU’s to check the line. This can save you a
considerable amount of time, since the more equipment you have on the line, the
more difficult it becomes to determine where a problem is occurring.
The BR Router provides one high-speed V.35 synchronous interface, and one RS-
232 sync/async interface, each of which can be independently configured for PPP or
Frame Relay operation. The V.35 interface is capable of communicating to another
router or a PPP client machine over a 56K CSU/DSU, an ISDN Terminal Adapter,
or a T1 CSU/DSU. The RS-232 interface is capable of communicating to another
router or a PPP client machine over a modem, 56K CSU/DSU, or ISDN Terminal
Adapter.
V.35 Interface
The BR Router does not include a V.35 cable. These cables are available from your
reseller, or a number of other suppliers. The BR Router has a female V.35
connector, as do virtually all line communications devices. Thus, the V.35 cable
required to connect to a line communications device will usually have male
connectors at both ends. The pinouts for this cable are shown in Appendix B.
RS-232 Interface
The BR Router includes one DB-25 to DB-25 RS-232 sync/async cable. This cable
supports RS-232 asynchronous modems, synchronous leased and switched 56K
CSU/DSU’s, and ISDN Terminal Adapters. It can also be used to connect the
router’s auxiliary interface to a PC running terminal emulation software, or to a
dumb terminal.
v Note: Please use only the supplied DB-25 cable when connecting your line
communication device to the BR Router’s RS-232 interface. The cables provided
with other equipment will generally not have the same internal connections.

BR Router Back Panel
This section of the manual describes how to connect the BR Router to your Ethernet
network and your wide area communications device(s). In summary, the steps for
installation are:
1. Make sure the router is powered down and not plugged in to the wall.
2. Connect the router to the Ethernet network.
3. Connect the router to the wide area line communications device(s).
4. Power up the line communications devices.
5. Plug in the power cable and power up the router.
Mounting the Router
The BR Router is meant to be left standalone on a desktop or equipment table.
v Note: When stacking other equipment on the BR Router, do not exceed 25 pounds
of evenly distributed weight on top of the router. Additional weight may bend the
case.
Connecting the Router to the Ethernet
If your twisted-pair hub is already in place, you can connect the router to an active
network without interrupting network activity.
14
Connecting to Twisted-Pair Ethernet
Before connecting the router to twisted-pair cabling you need an unshielded twisted-
pair cable that is already connected to your 10BaseT-compatible twisted-pair hub.
To connect the router to the twisted-pair network, simply plug the twisted-pair cable
into the RJ-45 connector on the back of the unit.
Connecting a Line Device to the BR Router
The BR Router supports high-speed synchronous operation over a V.35 connector.
It also supports lower speed synchronous/asynchronous operation over an RS-232
connector.
The BR Router independently supports PPP and Frame Relay link protocols on each
WAN interface.
Connecting Devices to the V.35 Interface
This interface -- WAN 0 -- can be used to connect to a wide variety of line
communications devices, including those which support either leased or dialed
operation. Examples include leased 56K CSU/DSU’s, switched 56K CSU/DSU’s,
fractional T1 CSU/DSU’s, ISDN terminal adapters, and full T1/E1 rate
CSU/DSU’s.
You may select either dial-on-demand, redial if down (“always up” mode), or leased
line operation. This interface may also be set to receive ISDN or switched 56
incoming calls.
To connect a device, first make sure that both units are powered off. Then, simply
connect a V.35 cable (not supplied) between the router and the device.
Connecting Devices to the RS-232C Interface
This interface -- WAN 1 -- can be used to connect to synchronous or asynchronous
line communications devices at rates up to 256Kbps (sync), or (230.4 Kbps (async).
Examples include modems, leased or switched 56K CSU/DSU’s, and ISDN
terminal adapters.
You may select either dial-on-demand, redial if down (“always up” mode), or leased
line operation. This interface may also be set to receive ISDN or switched 56
incoming calls.
To connect a device, first make sure that both units are powered off. Then, simply
connect the supplied RS-232 cable between the router and the device.
v Note: The BR Router RS-232 interfaces require that your asynchronous line
communications device be set to supply the RS-232 DCD signal when a connection
has been made. A synchronous RS-232 device should be set to provide DSR.
15
v Note: The BR Router includes a special cable to facilitate connections to RS-232
line communications devices. This cable includes support for several asynchronous
and synchronous control signals. Off-the-shelf cables generally do not support
these signals.
Connecting an Out-of-Band Management Console
If you wish to connect an out-of-band management console, use the supplied cable
and connect to the AUX/Console interface on the back of the BR Router. You can
use a dumb terminal or a computer equipped with VT100 terminal emulation.
The default baud rate for the AUX/Console interface is 9600.
Powering Up the Router
Power up all modems, CSU/DSU’s, and TA’s before powering up the router. This
allows the router to immediately sense which of its interfaces are connected. At
power-up, the router will take approximately one minute to become visible to
RouterView.
v Note: If you want to use Telnet as a management method, you must first
configure an IP address into the router with an out-of-band console, with
RouterView, or with a reconfigured IP host or workstation on the same Ethernet
segment as the router. See the chapter in this manual on Setting Up Command
Line Management.
17
Chapter 4 - RouterView Software
Installation
All of the routers in DCB’s multiprotocol family, can be managed from a single
management platform called RouterView. Both a Windows and a Macintosh
version of RouterView were included with your BR Router.
v Note: Although the installation procedures for the Windows and Macintosh
versions of RouterView are slightly different, the programs themselves are virtually
identical. Once you have installed RouterView on the platform of your choice, you
can find more information on how to use it in the RouterView Reference Guide
which was included with your router.
RouterView for Windows
RouterView for Windows allows you to manage the BR Router from an IBM-
compatible PC running Windows 3.1, Windows for WorkGroups, Windows 95, or
Windows NT. The PC can either be configured as an IPX client on a Novell
NetWare internet, or as an IP WinSock client on an IP internet.
System Requirements
In order to successfully run RouterView for Windows, you need:
•
•
IBM PC or compatible w/ 386 or later processor
Windows 3.1, Windows for Workgroups, Windows 95, or Windows NT
installed
•
VGA or better monitor
And an IPX configuration or an IP configuration (or both) consisting of:
•
A Windows 3.1 Novell IPX client configuration, using IPXODI.COM
- or -
A Windows for Workgroups, Windows 95, or Windows NT machine running
IPX/SPX Compatible Transport
•
A WinSock client configuration on an IP network
v Note: The “IPX 101” appendix to the RouterView Reference Guide contains
some tips on getting Novell’s IPX ODI running on your Windows client machine.
v Note: To choose the active transport protocol on a Windows machine which has
both IPX and IP installed, select “Options” from the Administration menu and
click the appropriate radio button.
18
Installation and Operation
This version of the RouterView program can be found on a 3.5-inch diskette labeled
“RouterView - Windows Disk” that was included with your BR Router.
Start Windows. Insert the diskette into your computer’s disk drive. At the
Windows Program Manager, select “Run” from the File menu and type A:SETUP
(where A: is the drive containing the RouterView diskette). This will invoke an
auto-installation program supplied with RouterView.
The installation program will ask you to select (or create) a directory in which it
should locate RouterView and its associated files and database subdirectory.
Once the installation is complete, double click on the RouterView icon to open the
program. For further information on using RouterView, see the RouterView
Reference Guide included with your router.
v Note: RouterView will be able to use the transport protocol (IP or IPX) you have
selected to access DCB routers anywhere on your internetwork. This means you
can use the IP transport option to manage routers across the Internet.
v Note: For an up-to-date description of the changes (if any) made to Windows
system files by the installation program, see the README.TXT file located in the
RouterView installation directory.
RouterView for Macintosh
RouterView for Macintosh allows you to manage the BR Router from an Apple
Macintosh or compatible computer. RouterView for Macintosh uses the AppleTalk
protocol to communicate with the router.
System Requirements
A Macintosh version of RouterView was included with your router. You can run
RouterView from any Macintosh on your network that meets the following technical
specifications:
•
•
Macintosh with 68030 or later processor (including PowerPC)
System 7.0 or later.
v Note: Although older Macintoshes such as SE/30’s and IIsi’s will run
RouterView adequately for infrequent use, a newer/faster machine is preferable for
larger networks where RouterView will be used more often.
Installation and Operation
To install RouterView for Macintosh, simply insert the RouterView diskette into the
floppy drive of your Macintosh. Then double click on the self extracting archive
(.sea) icon. You will be asked where you would like to locate your copy of the
RouterView program and data files.
19
Double-click on the RouterView icon and the program will start up and ask you to
select/create a location for its data files. Once the data files have been created, this
message will not reappear when you run RouterView.
For further information on using RouterView, see the RouterView Reference Guide
included with your router.
21
Chapter 5 - Command Line
Management
The command-line interface allows you to configure and monitor the router in-band
via Telnet or out-of-band with a terminal connected to the BR Router’s
AUX/Console interface.
Telnet is a remote terminal communications protocol based on TCP/IP. With
Telnet you can log into and manage the router from anywhere on your IP
internetwork, including across the Internet if you choose. To do this, you must run
Telnet client software on your local computer, which will communicate with the
Telnet server built into the router.
In order to be able to access the command-line interface via Telnet, you must first
set some IP parameters in the router.
You can set basic IP parameters out-of-band using the AUX/Console interface and a
terminal or a PC with terminal emulation software, or in-band with a reconfigured
IP host or RouterView.
After the IP parameters are set and saved to Flash ROM, you can complete the
configuration in-band with Telnet.
Out-of-Band Command Line Management
You can use command line management out-of-band as a permanent management
method, or only temporarily in order to set the router’s IP parameters to allow in-
band Telnet access.
In order to access the command line out of band, set a terminal or a PC to a baud
rate of 9600, and connect it to the router’s AUX/Console interface using the cable
which was supplied with the router. Press the <Return> key one or two times.
Enter the default password letmein at the password prompt. The command line
interface prompt will appear on the screen.
If you plan to use out-of-band access for ongoing management of your router, you
can find further information on using the command line interface in the Command
Line Reference Guide that was supplied with your router. Otherwise, see the
section below (Setting Up Telnet Operation) for information on setting the router to
allow Telnet access from hosts on its network.
22
Temporarily Reconfiguring a Host for Command Line
Management
You can temporarily reconfigure an IP host in order to set the router’s IP
parameters to allow in-band Telnet access. Once you have set these parameters you
will want to change the host’s configuration back to its original settings.
If you wish to set the router’s basic IP parameters in this fashion, the host must be
on the same Ethernet segment as the router’s Ethernet interface. You can set the
host’s IP address to 198.41.12.2, with a class C mask (255.255.255.0) and then
Telnet to 198.41.12.1.
Enter the default password letmein at the password prompt. The command line
interface prompt will appear on the screen.
See the next section (Setting Up Telnet Operation) for information on setting the
router to allow Telnet access from hosts on its network.
Setting Up Telnet Operation
In order to communicate to the router via Telnet from any host on your IP
internetwork, you must complete basic IP configuration for the router interface
which is connected to your Ethernet.
Basic IP configuration can be done using the interface, set ip, and save commands
from a console or a reconfigured host. For more information on these commands,
see the interface(misc), ip(set), and save(misc) commands in the Command Line
Reference Guide which was supplied with your router.
The required parameters for Telnet access to an interface are the IP address, IP
subnet mask, and IP broadcast address. To change the configuration parameters in
the BR Router, the router will request a password. The default for this password is
also letmein.
After you have set these basic IP parameters, you can use Telnet to access the router
from any node on your IP internetwork. Invoke the Telnet client on your local host
with the IP address of the router you wish to manage.
v Note: Proper syntax is vital to effective operation of the command line. Case is
not significant – you may enter commands in upper case, lower case, or a
combination of the two.
23
Chapter 6 - Quickstart Instructions
This Quickstart section briefly discusses the major parameters that must be set in
order to use the router.
This section does not include information on setting up packet filters for using the
router as a Firewall. See the RouterView manual or Command Line manual
regarding IP packet filters for more information.
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 section.
In this section:
RV = RouterView
CL = Command Line
v Note: 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 configuring or changing the configuration of
your BR Router.
v Note: Considerably more information on the meaning of the router’s parameters
is provided in the RouterView Reference Guide and the Command Line 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 RouterView
Reference Guide.
Ethernet Interface Configuration
Ethernet interfaces are considerably easier to set up than wide area interfaces since
there are no choices that need to be made regarding line communications devices
and their parameters. We recommend that you begin by configuring any Ethernet
interface parameters before proceeding to configure WAN interface parameters.
24
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
RV: Use the Ethernet - IP screen to set these parameters.
CL: Use the interface(misc) and ip(set) commands.
Suggested for IP
These parameters help supply information about the segment that the interface is
connected to. With this information, routing can take place.
•
IP RIP 1 (Routing Information Protocol version 1)
and/or
•
IP Static Routes
RV: Use the Ethernet - IP screen to set RIP, and the IP Static Routing Window (All
- IP) to set static routes.
CL: Use interface(misc) and ip flags(set) to set RIP, and ip route(add) to add
static routes and a default route/router.
IPX Protocol
Required for IPX
There are generally 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 autoadapt to conditions on the Ethernet.
Suggested for IPX
You may want to set your own network numbers, rather than using the
autoconfigured values. You may also want to turn off unused frame types.
RV: Use the Ethernet - IPX screen.
CL: Use interface(misc) and ipx(set).
25
AppleTalk Protocol
Required for AppleTalk
There are generally no required changes from the shipping Ethernet configuration
for AppleTalk. The Ethernet interface will autoconfigure to use AppleTalk Phase 2,
and will autoadapt to conditions on the Ethernet.
Suggested for AppleTalk
You may want to set your own network numbers, rather than using the
autoconfigured values. You may also want to use more meaningful zone names.
RV: Use the Ethernet - AppleTalk screen.
CL: Use interface(misc) and appletalk(set).
DECnet Protocol
Required for DECnet
The router’s shipping configuration does not have DECnet turned on. You must
turn it on and set several DECnet parameters.
•
•
•
Turn DECnet on
Set DECnet area
Set DECnet node
RV: Use the Main DECnet screen (All - DECnet).
CL: Use decnet(set).
Suggested for DECnet
Setting the parameters above should be adequate for most installations.
WAN Interface PPP Configuration
This section covers the settings required for PPP (point-to-point) protocol operation
of the BR Router WAN interfaces. In general, the parameters listed here should be
set for each WAN interface on which you plan to use PPP. Note that one WAN
interface can be running PPP while the other is running Frame Relay.
There are a few differences between the capabilities of the V.35 WAN interface and
the RS-232 WAN interface. The V.35 interface can only be run synchronously, at
rates up to 2 Mbps per second. The RS-232 interface can be run synchronously or
asynchronously, at rates up to 256Kbps (sync), or 230.4Kbps (async).
26
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 about the segment that the interface is
connected to. With this information, routing can take place.

v Note: If you set RIP to “on” for a dial-on-demand link, you must also set the
update method to triggered to avoid the link being brought up by transmission of
RIP information. You should only use triggered operation when you are connecting
to another DCB router at the other end of the link.
RV: Use the WAN - IP screen to set RIP and the update method, and the IP Static
Routing Window (All - IP) to set static routes and a default route/router.
CL: Use interface(misc) and then ip flags(set) to set RIP, and ip wan(set) to set
the update method, and ip route(add) to add static routes and a default route/router.
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.
Suggested for IPX
If you plan to use dial-on-demand for this link, you should set the update method
“triggered” to avoid the link being brought up by transmission of IPX RIP
information. You should only use triggered operation when you are connecting to
another DCB router at the other end.
When you set up an on-demand link with IPX, you should carefully monitor link
usage to determine whether the link is being activated only when it is needed.
Additional router configuration will be required for many networks in order to
achieve optimal link usage.

Update Method
RV: Use the WAN - IPX screen.
CL: Use interface(misc) and then ipx wan(set).
AppleTalk Protocol
Required for AppleTalk
WAN interfaces which are set for PPP operation do not generally use an AppleTalk
address. They are set to act as an “unnumbered interface.” In this mode of
operation, there are no required settings.
Suggested for AppleTalk
If you plan to use dial-on-demand for this link, you should set the update method to
triggered to avoid the link being brought up by transmission of AppleTalk RTMP
information. You should only use triggered operation when you are connecting to
another DCB router at the other end.
When you set up an on-demand link with AppleTalk, you should carefully monitor
link usage to determine whether the link is being activated only when it is needed.
Additional router configuration will be required for many networks in order to
achieve optimal link usage.
•
Update Method
RV: Use the WAN - AppleTalk screen.
CL: Use interface(misc) and then appletalk wan(set).
DECnet Protocol
Required for DECnet
WAN interfaces which are set for PPP dial-on-demand operation should have their
DECnet hello timers and DECnet routing timers set for a fairly long period, since
the link will be brought up when this information is transmitted.
Because of the need to regularly bring the link up to exchange routing information,
on-demand operation using DECnet is not recommended.
•
•
Hello timer
Routing timer
RV: Use the WAN - DECnet screen.
CL: Use interface(misc) and then decnet wan(set).
28
Link Configuration
Required for Dedicated/Leased Line Operation
Dedicated line operation is the simplest to set up.
•
•
Set Dedicated connection
Set PPP connection
RV: Use the WAN - Link screen.
CL: Use interface(misc) and then wan connect(set).
Suggested for Dedicated/Leased Line Operation
Dedicated line operation generally does not require additional parameters for
operation.
Required for Dial-On-Demand Operation
Incoming dial-on-demand operation requires only slightly more information than
dedicated line setup. Outgoing dial-on-demand requires additional information (see
the suggested settings below).
•
•
•
Set dial-up connection
Set PPP connection
Set to allow dial-in and/or dial-out
RV: Use the WAN - Link screen.
CL: Use interface(misc) and then wan connect(set).
Suggested for Dial-On-Demand Operation
Outgoing dial-on-demand requires some additional information.
•
•
•
•
Set dialing method
Create dial-out script
Set dial-out script to be used
Set inactivity time
RV: Use the WAN - Link window to set the dialing method and to select a chat
script (once you have created one). Use the Chat Script Editor window (All - Link)
to create your chat script.
CL: Use interface(misc) and then wan connect(set) to set the dialing method and
inactivity time, and to select a chat script (once you have created one). Use the
chat(edit) command to create a chat script.
29
Physical Communications Settings
You may need to set the baud rate, sync/async operation, and other physical
communications parameters for the WAN interface. These parameters will depend
on the line communications device you are using.
RV: Use the WAN - General window.
CL: Use interface(misc) and then wan serial(set).
WAN Interface Frame Relay Configuration
This section covers the settings required for Frame Relay operation of the BR
Router WAN interfaces. In general, the parameters listed here should be set for
each WAN interface on which you plan to use Frame Relay. Note that some WAN
interfaces can be running Frame Relay while others are running PPP.
There are a few differences between the capabilities of the V.35 WAN interface and
the RS-232 WAN interface. The V.35 interface can only be run synchronously, at
rates up to 2 Mbps per second. The RS-232 interface can be run synchronously or
asynchronously, at rates up to 256Kbps (sync), or 230.4Kbps (async).
IP Protocol
Required for IP
Frame Relay operation requires that the WAN interface is set to be a “numbered
interface.” This means that the interface (and thus the Frame Relay network) must
have an IP address, etc.
•
•
•
•
IP numbered interface
IP Address
IP Subnet mask
IP Broadcast Address
RV: Use the WAN - IP screen to set these parameters.
CL: Use the interface(misc) and ip wan(set) commands.
Suggested for IP
These parameters help supply information about the segment that the interface is
connected to. With this information, routing can take place.

IP Static Routes
•
IP Default Route/Router
RV: Use the WAN/IP screen to set RIP, and the IP Static Routing Window (All -
IP) to set static routes and a default route/router.
CL: Use interface(misc) and then ip flags(set) to set RIP, and ip route(add) to add
static routes and a default route/router.
IPX Protocol
Required for IPX
Frame Relay operation requires that the WAN interface is set to be 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
RV: Use the WAN - IPX screen.
CL: Use interface(misc) and then ipx wan(set).
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 is set to be 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 Number
RV: Use the WAN - AppleTalk screen.
CL: Use interface(misc) and then appletalk wan(set).
31
Suggested for AppleTalk
The settings above are all that is generally required for AppleTalk operation over
Frame Relay.
DECnet Protocol
Required for DECnet
WAN interfaces which are set for Frame Relay operation do not need any additional
parameters set in order to function.
Link Configuration
Frame Relay is presently supported in the BR Router only via synchronous
dedicated line operation.
•
•
•
Set interface for Synchronous operation
Set Dedicated connection
Set Frame Relay connection
RV: Use the WAN/Link screen.
CL: Use interface(misc), wan serial(set), and wan connect(set).
Suggested for Dedicated/Leased Line Operation
Dedicated line operation generally does not require additional parameters for
operation.
Frame Relay DLCI Mappings
If you are connecting to another DCB router, this information is not required for
Frame Relay operation. DCB 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 one of your BR Router interfaces will be connected to an ISP via Frame Relay,
check with your ISP technical staff on whether you must manually enter DLCI
information or not.
RV: Use the DLCI Mapping Database window.
CL: Use interface(misc) and then frelay(set).
32
Physical Communication Settings
You may need to set the baud rate, sync/async operation, and other physical
communications parameters for the WAN interface. These parameters will depend
on the line communications device you are using.
RV: Use the WAN - General window.
CL: Use interface(misc) and then wan serial(set).

standard RS-232 pin outs. Note that the data interface may be set for synchronous
operation and in this mode the data interface will use the clock lines provided by
RS-232.

Appendix C - LED Patterns and Test
Switch Settings
BR Router LED Patterns
The BR Router uses a number of light patterns on its front LED bars to indicate
operating conditions.
Power On, No Traffic
The router will scan through the left (Ethernet) LED bar, from left to right,
illuminating one element at a time.
v Note: Lights 1 and 10 on the Ethernet bar are directly connected to the router’s
10BaseT interface and indicate 10BaseT link (1) and 10BaseT polarity (10).
Ethernet Traffic Indicators (Ethernet LED Bar)
Scan from 2 to 5: Ethernet transmit packet
Scan from 9 to 6: Ethernet receive packet
Other Indicators (on All LED Bars)
Transmit and receive packets - per WAN interface as marked on front label.
5,6 flashing: Router stacks starting up
3,4 & 7,8 flashing: No OS loaded. Running from ROM.
5,6 on solid, 2 (bars 1 & 3) and 9 (bars 2 & 4) flashing : Erasing OS in Flash ROM
4,5,6,7 on solid, 2 (bars 1 & 3) and 9 (bars 2 & 4) flashing : Erasing config in
Flash ROM
Scanning from 2 to 9 (bars 1 & 3), and scanning from 9 to 2 (bars 2 & 4): Flash
ROM erase due to switch setting five or six is complete. Set switch to zero and
cycle power.
Panic Indicators
Any continuous flashing pattern not noted above may be caused by a software
“panic.” This is a sign that a condition has been detected that the software does not
know how to deal with: either an unusual network condition, or a hardware failure.
Please call DCB Technical Support if your router shows a software panic.
