Default Setup
The standard LAPD configurations are shown in Table 9 on page 86 (Basic Rate
Interfaces) and Table 10 on page 86 (Primary Rate Interfaces). These settings
suit many situations. However, you can modify these settings as required to
suit other network situations (see the Integrated Services Digital Network (ISDN)
chapter in the Software Reference).
Testing the BRI or PRI PIC
To test the ISDN PRI, BRI (U), or BRI (S/T) PIC you need to configure a routing
protocol such as IP or IPX to use ISDN.
For more information about configuring ISDN calls and routing protocols, see
“Configuring ISDN (models with PIC bay)” on page 87, “Configuring an IP
Network” on page 99, and “Configuring a Novell IPX Network” on page 111.
