Item No. : VIC2-2E/M

Product Description: Two-port E&M VIC*

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.

In order to troubleshoot, refer to the TAC Case Collection ( registered customers only) tool.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on these E&M VICs:

  • VIC-2E/M

  • VIC2-2E/M

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Product Numbers

  • VIC-2E/M—Two-port E&M VIC

  • VIC2-2E/M—Two-port E&M VIC*

Note: * “VIC2” indicates a next-generation VIC, with component refresh. VIC-2E/M is not supported in the Cisco IP Communications Voice/Fax Network Modules (NM-HD-1V, NM-HD-2V and NM-HD-2VE). VIC2-2E/M should be used with them. Refer to the Voice Hardware Compatibility Matrix for more information.

Description

Voice ports

Two E&M ports

Connections

Supports two-wire and four-wire, E&M signaling types I, II, III, 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 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 12.2(15)ZJ, 12.3(4)T, and later

Requires a "Plus" feature set

 

Configuration

Refer to Voice over IP for the Cisco 3600 Series for the configuration of voice features in Cisco IOS Software.

Note: In Cisco IOS Software, use the global configuration command voice-port slot/VIC slot/unit to configure the voice port parameters.

Before you configure the VIC E&M, be sure you understand the different interface types and wiring arrangements that an E&M port can have. E&M interface types can be type I, II, III, or V. Cisco platforms do not support type IV. Wiring arrangements can be two or four wires. Refer to Understanding and Troubleshooting Analog E&M Interface Types and Wiring Arrangements for more information.

Also, you need to understand the different types of Start Dial Supervision signaling that an E&M port can have. Start Dial Supervision is the line protocol that defines how the equipment seizes the E&M trunk and passes the address signaling information. The equipment sends dual tone multifrequency (DTMF) digits in order to pass the address information. On E&M circuits, the three main Start Dial Supervision protocols are:

  • Immediate Start

  • Wink Start

  • Delay Dial

Refer to Understanding and Troubleshooting Analog E&M Start Dial Supervision Signaling for more information.

The commands to configure the voice port are:

Router(config-voiceport)# ?
busyout Configure busyout monitoring parameters
comfort-noise Use fill-silence option
connection Specify Trunking Parameters
cptone Configure voice call progress tone locale
dial-type Configure type of dialer for voice
echo-cancel Echo-cancellation option
impedance Specifies the terminating impedance of the interface
input Configure input gain for voice
music-threshold Threshold for Music on Hold
non-linear Use non-linear processing during echo cancellation
operation Specify the operation of the E&M signal
output Configure output attenuation for voice
shutdown Take voice-port offline
signal Configure signal parameters
snmp Modify SNMP voice port parameters
timeouts Configure voice timeout parameters
timing Configure voice timing parameters
type Specifies the E&M interface type

The most important parameters are:

  • cptone

  • dial-type

    • dtmf—touch-tone dialer

    • pulse—pulse dialer

  • impedance

    • 600c

    • 600r

    • 900c

    • complex1

    • complex2

  • operation

    • two-wire operation

    • four-wire operation

  • signal

    • delay-dial

    • immediate

    • wink-start

  • type

    • E&M type I

    • E&M type II

    • E&M type III

    • E&M type V

The commands to configure VoIP on Cisco routers are very similar on all the router platforms that the Platform Support section of this document shows. Refer to the Command Lookup Tool ( registered customers only) for more information on the commands in this document.

Refer to the Fine-Tuning E&M Voice Ports section of Configuring Voice Ports for Voice over IP to fine-tune E&M voice ports.

Refer to Analog E&M Troubleshooting Guidelines (Cisco IOS Platforms) in order to troubleshoot.

Platform Support

VIC-2E/M

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.
