Configuring X.25 over a D Channel (BRI only)
Using the BCC and Site Manager, you can configure X.25 over a D channel. This
feature is only for NET3 switch types in Germany and France
To reduce the cost of connecting to an X.25 network, you can send X.25 packets
over an ISDN D channel instead of sending them over leased lines. To use the D
channel for X.25 packet transmission, the baud rate must be a maximum of
9600 bps so data is not lost. For more information about this feature, see
Chapter 5, “Implementation Notes for All Dial Services.”
You should have already created BRI service according to the instructions in
Chapter 2, “Starting Dial Services Using Site Manager” or Chapter 3, “Starting
Dial Backup Using the BCC.” To modify this feature, go to one of the following
sections.
Using the BCC
You can enable or disable X.25 service over the D channel for each BRI line. To
do so enter:
x25-isdn-dchannel
<
enabled/disabled
>
For example:
bri/1/1/# x25-isdn-dchannel enabled
The default is disabled.
If you enabled X.25 over a D channel, go to “Setting the TEI Parameters for X.25
Service over the D Channel” on page 9-45.
Caution:
If you enable or disable this feature dynamically, the router
disconnects all existing calls across the B channels as the ISDN software
makes changes for the feature. Once the changes are complete, the software
restarts and you can make calls again.
