ISDN BRI WAN Interface Cards ISDN BRI S/T Leased-Line WAN Interface Card 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 Step 3 Connect one end of a straight-through RJ-48C-to-RJ-48C cable to the RJ-48C port on the ISDN BRI U WIC. Connect the other end of the cable directly to the ISDN wall jack as shown in Figure 53.

Check that the OK LED goes on, which indicates that the ISDN port has established a connection with the central office switch.
