To connect an ISDN BRI U WIC to a network, follow these steps:
Step 1 Confirm that the router is turned off.
Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the 1-port ISDN BRI WIC with U interface, version 2 (WIC-1B-U-V2) only to intra-building or
unexposed wiring or cable. The intra-building port(s) of the equipment or subassembly must not be
metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are
designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in
GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary
Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
Step 2 Connect one end of a straight-through RJ-48C-to-RJ-48C cable to the RJ-48C port on the ISDN BRI U
WIC.
Step 3 Connect the other end of the cable directly to the ISDN wall jack as shown in Figure 53.

Step 4 Turn on power to the router.
Step 5 Check that the OK LED goes on, which indicates that the ISDN port has established a connection with
the central office switch.
