Adding trunks to a trunk group example

Last Updated : Sep 26, 2023 |

About this task

Use this procedure to add new trunks or to change the assignment of existing trunks. To change the assignment of existing trunks, remove them from their current trunk group and add them to the new group.

You must add a trunk group before you can assign and administer individual trunks. To add a new trunk group, see the instructions in this chapter for the type of group you want to add.

As an example, we will assign 5 trunks to a new tie trunk group, trunk group 5. We’ll use ports on several media modules for members of this group.

Procedure

  1. Enter change trunk-group 5.
  2. Click Next Page to move to the Group Member Assignments screen.

    Some of the fields on this screen do not appear for every trunk group.

  3. In the Port field in row 1, enter 002V4.

    This field assigns the first member of the trunk group to a port on a media module.

  4. In the Name field in row 1, enter 5211.

    This is the extension assigned to this trunk. In general, type the circuit ID or telephone number for each trunk in this field. The information is helpful for tracking your system or troubleshooting problems. Update these fields whenever the information changes.

  5. In the Mode field, enter e&m.
    Caution:

    An entry in this field is only required for some media modules. Dip switch settings on the media module control the signaling mode used on the trunk group, so the entry in the Mode field must correspond to the actual setting on the media module.

  6. In the Type field, enter t1-comp.

    An entry in this field is only required for some media modules.

  7. Repeat steps 3 to 6, as appropriate, for the remaining trunks.

    Notice that you can assign trunks in the same trunk group to ports on different media modules.

  8. Select Enter to save your changes.
