Displaying and Configuring CVM Cards

Displaying and Configuring CVM Cards

The Channelized Voice Module (CVM) is a multipurpose front card. A CVM circuit line can carry the following types of traffic:

  • Voice

  • Data

  • Combination of voice and either low-speed or high-speed data

Displaying Card Parameters

To display the Card Configuration dialog for this device (using the rear or front view), right-click on the card to display the card "Configure" pop-up menu, then select Configure.

The parameters are described in Table 11-5.


Table 11-5: Voice Channels Dialog Parameters
Parameter Description

Channel Index

Specifies the channel or range of channels for the interface type configuration.

Interface Type

Specifies the interface type to assign to the channel or range of channels.

Dial Type

Specifies the dial type to assign. The three possible dial types are:

  • inband

  • pulse

  • user-configured

Inband is the default dial type.

Signaling Delay(msecs)

Specifies the signaling delay for the user-configured dial type. The range is 12-96 ms. Your entry is rounded to the closest multiple of 1.5 ms.

Min. Wink(msecs)
