Trunk Groups

A trunk group is a logical grouping of multiple DS1 interfaces with the same signaling characteristics that can be provisioned as the target of an outbound dial peer.

VRC only discovers and displays trunk groups for gateways. VRC does not provision trunk groups.

You can edit the attributes of a trunk group using the VRC client, but you must use the command line interface to add or delete the trunk group from the gateway. You can configure multiple trunk groups per gateway.

Note: You can only use a VRC-discovered trunk group in your dial plan if the associated gateway has a VRC feature set of dp1.1 or later.

You can view the trunk groups that are assigned to the gateway in the Design View or the Baseline View.

Use this procedure to edit the attributes for a trunk group on a gateway.

Procedure

You must be in the Design View to edit trunk group attributes.

  1. Expand the dial plan tree to view all components.

  2. Select the gateway with the trunk group you want to edit.

  3. Select the Trunk Group tab.

  4. Double-click the trunk group you want to edit.

  5. Click Edit Attributes. The Edit Trunk Group dialog box appears.

  6. Enter the trunk group attribute information you want to change.

  7. Click Apply to apply the values.

Trunk group entry fields are described in the following table:

Incoming Translation Profile

Associates a translation profile for the incoming side of the gateway. The VRC feature set of the translation profile must be dp1.1 or later.
