Cisco voice interface cards (VICs) support voice technologies. VICs can be installed in interface card slots on supported Cisco access routers or in 1- or 2-slot voice network modules that are installed in network module slots on supported Cisco access routers.
RecEive and transMit (E&M) is a signaling technique for 2-wire and 4-wire telephone and trunk interfaces. The E&M interface typically connects remote calls from an IP network to a PBX. The Cisco
2-port E&M voice interface card is shown in Figure 1.
The E&M voice interface card has one IN USE LED for each port. Table 1 describes the functions of the LEDs.

Before connecting a VIC to the network, ensure that the VIC is installed in the router, the equipment is properly grounded, and you have the proper cables for connecting the VIC to the network. This section describes the preparation necessary before connecting a 2-port E&M VIC to the network.
Install the Cisco 2-port E&M VIC according to the instructions in Installing Cisco Interface Cards in Cisco Access Routers.
Ensure that the equipment you are working with is properly grounded according to the instructions in Installing Cisco Interface Cards in Cisco Access Routers .
Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the 2-port E&M card (VIC2-2E/M) only to intrabuilding or nonexposed 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-48C-to-RJ-48C cable to an RJ-48C port on the card. (See Figure 2.)
