VIC Cables and Pinouts
This section describes the VIC cables and pinouts for foreign exchange station
(FXS), foreign exchange office (FXO), and E&M connectors. Use the following
cables to connect the VICs to the network:
• Standard RJ-11 modular telephone cable to connect FXS VIC ports
(color-coded gray) to a telephone or fax machine.
• Standard RJ-11 modular telephone cable to connect FXO VIC ports
(color-coded pink) to the PSTN or to a PBX that does not support E&M
signaling.
• Standard RJ-48S connector and cable to connect E&M VIC ports
(color-coded brown) to a PBX line. The cable wiring depends on the PBX
type and connection. For details refer to the Cisco WAN Interface Cards
Hardware Installation Guide.
Figure 2 shows how to connect the VICs to the network.
