–PRI

–Leased line

•ISDN configuration examples

Caution: Configuration of XSR 1200 Series routers is significantly different than for XSR 1800 and 3000 routers. For example, only interfaces FastEthernet 0, ATM 0, and BRI 0 (as well as their sub-interfaces) are configurable on the XSR 1200 Series. For more information, refer to the XSR 1220/1235 Getting Started Guide.

ISDN Features

The XSR’s BRI interface and T1/E1 controller in PRI mode acts as a utility that can set up and tear down calls under the control of higher level functionality, usually the Dialer. The ISDN module expects to receive from the Dialer a full description of the call to be placed will accept incoming calls only if screened by the Dialer. The XSR’s ISDN services BRI and PRI lines via the following NIMs on XSR 1800 and 3000 Series routers:

•1, 2 or 4 port Channelized NIM card for PRI lines.

•1 or 2 port BRI-S/T NIM card.

•1 or 2 port BRI U NIM card.
