If you install any of the following configurations, the Cisco IOS software disables certain ports, as shown
in Table 24:
• An ISDN BRI voice interface card in a 1-slot voice network module (NM-1V)
• Two ISDN BRI voice interface cards in a 2-slot voice network module (NM-2V)
• One ISDN BRI voice interface card and one analog voice interface card (VIC-2FXS, VIC-2FXO,
VIC-2FXO-EU, VIC-2FXO-M3, or VIC-2E/M) in a 2-slot voice network module (NM-2V)
Connecting ISDN BRI Interface Cards
Use a straight-through RJ-45 cable to connect ISDN BRI cards to the ISDN network through a telephone
wall outlet or other device.
Caution To prevent damage to the router, be sure to connect the BRI cable to the BRI connector only, and not to
any other RJ-45 connector.
To connect the 2-port ISDN BRI card to the router, follow these steps:
Step 1 Confirm that the router is still turned off.
Caution 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.
