Voice Interface Cards Receive and Transmit (E&M) Interface Cards Connecting FXO Cards Use a straight-through RJ-11 cable to connect the FXO voice interface card to the PSTN or PBX through a telephone wall outlet. Note Ports on this interface card are colored pink. 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 FXO card (VIC2-2FXO) 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. Step 2 Connect one end of the straight-through RJ-11 cable to an RJ-11 port on the card. (See Figure 86.)
