WAN Channel Assignment main screen
The next stage in configuring a Frame Relay link is to set the number of n x 64 channels on the T1/E1 that will
carry the data. Each channel is 64 kbps in speed and must correspond to the same channels that your provider
is using. Usually your provider will start from channel 1. For example: a 256-kbps link could be divided into
64-kbps channels numbered 1, 2, 3, and 4.
To set the channel assignment:
1. Click on
T1/E1 Link
under the
Configuration Menu
to to display the T1/E1 Link Activity main window
(see figure 71 on page 220).
2. Click on
Channel Assignment
in the appropriate Link: x section (for example, if the T1/E1 cable was con-
nected to port 2, you would click on
Channel Assignment
in the
Link: 2
section).
3. Click on the channel 1 drop-down menu and select
frameRelay(3)
.
Note
You can have some channels as a Frame Relay link on the same WAN
link that you are also using for dial-up calls. Each channel that is set
to Frame Relay will reduce the number of simultaneous calls. You also
must arrange with your provider to allow both Frame Relay and cir-
cuit-switched calls on the same WAN link.
4. Repeat step 3 to configure remaining channels.
5. Click Submit .
The link is now activated on your access server. The next stages will configure Frame Relay and IP routing.
