Cisco VIC-2E/M
Introduction
An Ear and Mouth (E&M) interface supports tie-line facilities or signals between telephone switches. You can use the E&M voice interface card (VIC) to integrate VoIP with the legacy voice solution. The E&M VIC connects the Cisco router to a PBX.
Features
| Feature | Description |
|---|---|
| Voice ports | Two E&M ports |
| Connections | Supports two-wire and four-wire E&M signaling types I, II, III, and V via RJ-45/RJ48S connectors. Both ports must use the same signaling type. For E&M VIC pinouts, refer to the VIC-2E&M Pinout section of the document E&M Cable Pinouts to Connect Cisco 1750/2600/3600 E&M VIC to Nortel PBX Option 11 E&M Trunk. |
| Cisco IOS® Software Release | Requires Cisco IOS Software Release 11.3(1)T or later For Australia, requires Cisco IOS Software Release 11.3(6)T Requires a "Plus" feature set |
Platform Support
The table in this section shows the platforms that support the various E&M VICs. The table includes Cisco IOS Software release support selection.
Note: The original VIC works in Cisco NM-1V and NM-2V network modules, and VIC2 works in NM-HD-1V, NM-HD-2V, NM-HD-2VE, and NM-HDV2. These are not interchangeable.

1Voice requires a Cisco IOS "Voice" feature set on the Cisco 1700 series and "Plus" feature set on the Cisco 2600/3600/3700 series.
2The 3631 does not support voice. Neither the Cisco Catalyst 4500/4000 or Catalyst 6500/6000 series switches support VIC-2E/M.
Note: On the 175x/1760, you need a packet voice/fax digital signal processor (DSP) module (PVDM) in order to support the VIC-2E/M. The PVDMs hold DSPs that make the card fully functional. You install these PVDMs on the motherboard within the 175x/1760. The 1750 requires a PVDM-4 for one VIC-2E/M and a PVDM-8 for two VIC-2E/Ms. On the 1751/1760 platforms, you need a second generation of PVDM:
- PVDM-256K-4 for one VIC-2E/M or VIC2-2E/M
- PVDM-256K-8 for two VIC-2E/Ms or VIC2-2E/Ms
The 1750 platforms do not support PVDM-256K-xx. Refer to Troubleshooting Unrecognized Voice Interface Cards on Cisco 1750, 1751, and 1760 Routers for more information about 1700 series voice gateway DSP resource requirements.
On the Cisco VG200, 2600, and 3600, the NM-1Vs and NM-2Vs come with the DSPs installed on the module.
Note: The Cisco IOS Software releases that the table provides are typically the minimum version that you need to support the platform, module, or feature in question. For a complete list of Cisco IOS Software releases that support a feature, module, interface card, or chassis, use the Software Advisor (registered customers only) tool.
