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

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.  
IP RIP 1 (Routing Information Protocol version 1)  
and/or  
IP Static Routes  
IP Default Route/Router  
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.  
 
27  
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 RIP 1 (Routing Information Protocol version 1)

30  
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).

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.
