Cisco Cisco VN 2900 Network Adaptation Interface Guía De Instalación

The Cisco 1751 and Cisco 1760 routers, and the Cisco ICS 7750 platform support both ISDN BRI 
NT/TE voice interface cards. You can install these cards in any interface card slot in these platforms. 
These platforms do not support the ISDN BRI S/T voice interface card.

The ISDN BRI NT/TE cards are illustrated in 

 and 

.

To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, 
connect the 2-port ISDN BRI card (VIC2-2BRI-NT/TE) only to intra-building or non-exposed wiring or 
cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

Cisco ISDN BRI interface cards support voice ISDN traffic only.

The ISDN BRI restrictions in this section do not apply to the VIC2-2BRI-NT/TE voice interface cards.

The ISDN BRI restrictions in this section do not apply to the Cisco 1751, Cisco 1760, or Cisco ICS 7750 
platforms.

To use all four voice channels, you must install the ISDN BRI card in slot 0 of a two-slot voice network 
module (NM-2V). Slot 1 should remain empty.

If slot 0 is unoccupied, the system treats it as a pair of analog voice ports.
