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.)
