Configuring the Nortel Networks Remote Access Concentrators and the DMS-10 for Remote Access.March 31, 1999 17

5.5.3 Setting up the WAN

There are two WANs associated with the RAC they can be configured as either ISDN PRI

or T1 A/B bit signaling trunk interface. The settings are made from the Admin prompt of

CLI.

Figure 9 shows a overview of the settings associated with a PRI configured WAN. The

correct syntax to addressing the WANs is to use “show wan=1 all”. The “wan=X”selects

which WAN is being addressed, where x= 1, 2 or all. Figure 9 shows a graphic of the set-

tings for a PRI configured WAN. Figure 10 shows a similar graphic of a WAN configura-

tion using a standard TI trunk interface.

The figures should be self explanatory in their setup. The following parameters will need

to be setup:

• switch_type - sets ust1 for a trunk interface or ni2 for PRI.

• line_code - set to AMI for ust1 or B8ZS for ni2.

• build_out - sets the build_out for the distance between the DMS-10 and the RAC.

• framing- set to D4 for ust1 or ESF for ni2.

• remote_address - this parameter sets a unique IP address for each B channel. It is not

required if the RADIUS server or DHCP will be setting the IP addresses.

• sigproto - this parameter is only valid for ust1. It sets the supervision for answering the

call.

The commands to set these parameters will be similar to the command to the “show”

command. With the exception of “remote_address” and “sigproto”. These com-

mands control B channel conditions so the command is structured as “set wan=1 b

remote_address 207.45.240.40 1” will set the first B channel of WAN 1 to IP

address 207.45.240.40 the next B channel to 207.45.240.41 till the last channel (23 chan-

nels for PRI or 24 channels for ust1).

Note

When a value has been changed from the default a “*” will

appear ned to the parameter.
