6. Create PPP interfaces.
Create PPP interfaces to use the ISDN calls. PPP provides the link layer
protocol and enables multiple network and transport layer protocols such
as IP and Novell® IPX to be carried over the same ISDN link.
For example, on the Head Office router create PPP interface 0 to use the
ISDN call ROHO, by entering the command:
CREATE PPP=0 OVER=ISDN-ROHO
On the Remote Office router, create PPP interface 0 to use the ISDN call
ROHO, by entering the command:
CREATE PPP=0 OVER=ISDN-ROHO
Check the configuration with the commands:
SHOW ISDN CALL
SHOW PPP
The call ROHO should appear in the output of the SHOW ISDN CALL
command. The output of the SHOW PPP command should show interface
ppp0 over ISDN-ROHO.
ISDN is now ready for use by routing protocols such as IP and IPX.

Configuring Primary Rate ISDN

Your router can operate in either TE or NT mode, using 75W or 120W
termination. The router is shipped with jumpers set to TE mode, 75W
termination, Tx grounded and Rx grounded via a 100nF capacitor. This is
appropriate for most situations. Your authorised distributor or reseller can
advise you whether or not to install grounding jumpers.
The following steps are required:
1. Check BRI hardware configuration.
1. Select the territory.
2. Set directory numbers and subaddresses.
3. Create call definitions.
4. Create PPP interfaces.
To configure Primary Rate ISDN follow these steps
1. Check BRI hardware configuration
Check that the AT-AR021(U) PIC has the correct termination for the local
conditions. The AR410 router can only operate in TE mode and is shipped
with the standard 100W termination jumpers removed. This is appropriate
for most situations, where the building wiring provides the ISDN
termination. Your authorised distributor or reseller can advise you
whether or not you should install termination jumpers.
