Supporting ISDN for the SSR-510
5-2
Ordering Your ISDN Line
You should order your basic rate ISDN service from your local telephone
company or PTT. When you order your ISDN service, request 64K circuit-
switched data on your “B” channels. The router does not support voice
services.
Table 5-1 lists the possible value for basic rate ISDN parameters. The
telephone company will provide you with the ISDN configuration parameter
settings for your service. You will need these to properly configure the router
for ISDN operation.
