3To configure the parameters of a specific trunk, from the trunks displayed on the top, select the trunk you want to configure by clicking the Trunks Status indicator. The first parameter named Trunk ID changes according to the trunk you click. The parameters displayed are for the selected trunk only.

4To modify the selected trunks parameters, click Stop Trunk; the trunk is stopped and the Trunk Configuration State parameter changes to Inactive. The parameters are no longer grayed and can be modified. The Apply Trunk Settings button appears at the bottom of the screen. When all trunks are stopped, the Apply to all Trunks button also appears at the bottom of the screen.

If the trunk cant be stopped because it provides the gateways clock (assuming the V7122 gateway is synchronized with the E1/T1 clock), assign a different E1/T1 trunk to provide the gateways clock or enable TDM Bus PSTN Auto Clock on the TDM Bus Settings screen.

To assign a different E1/T1 trunk that provides the gateways clock, access the TDM Bus Setting screen and change the TDM Bus Local Reference number to any other trunk number (this operation can be performed on-the-fly).

5From the Protocol Type drop-down list, select the required protocol. Note that different trunks can be defined with different protocols (CAS or ISDN variants) on the same gateway (subject to the constraints in the V7122 gateway Release Notes).

When modifying the Protocol Type field, the menu is automatically updated according to the selected protocol (ISDN, CAS or Transparent). Additional parameters are appropriate to the selected protocol type.

6From the Framing Method drop-down list, select the required Framing Method (for E1 trunks, always set the Framing Method to Extended Super Frame).
