# EDT FORCE FAILOVER

## Qualifiers:

ALL

<cabinet> <shelf> <slot> <port> (default port is 1)

## Purpose:

This command applies to the T1/E1 trunk resiliency feature. It allows you to force a resilient T1/E1 trunk to fail over immediately from the primary controller to the secondary controller.

Use this command to test the configuration of the T1/E1 trunks on the secondary controller without taking the primary controller out of service:

Perform this test when call traffic is low (for example, after business hours).

1. Enter this command on the primary controller to force the T1/E1 trunk to the secondary controller. Before you enter the EDT Force Failover command, use the State command to ensure that all the circuits are idle.

2. Check the front panel of the primary controller. The indicators on the T1/E1 Combo MMC should flash GREEN and RED.

3. Check the front panel of the secondary controller. The RED alarm indicator on the T1/E1 MMC should turn off and the GREEN status indicator should turn on steady.

4. Test the configuration of the resilient T1/E1 trunk by placing calls through the trunk while it is supported on the secondary controller.

5. Use the EDT Force Failback command to return support of the T1/E1 trunk to the primary controller. Before you enter the EDT Forced Failback command, use the State command to ensure that all the circuits are idle.

## Details:

- You must enter this command on the primary controller.

- All calls in progress on the T1/E1 Combo MMC card (PN 50005160) in the primary controller are dropped when support for the trunk is transferred to the secondary controller.

- You will receive an error message if you enter this command

- on the secondary controller

- without specifying the physical location ( PLID) of a T1/E1 Combo MMC card

- You can only issue this command from the Maintenance Commands form of the System. Administration Tool. You cannot enter this command from the local telnet maintenance terminal (port 2023).

- The ALL qualifier applies the command to all resilient T1/E1 trunk circuits on the controller.

NOTES

- Refer to the Resiliency Guide on the Mitel Customer Documentation site for instructions on how to install, configure, troubleshoot, and maintain T1/E1 trunk resiliency.

- You can use the Programmed Failback command to schedule the resilient T1/E1 trunk to automatically fail back from the secondary.

## Example:

### Entry: EDT FORCE FAILOVER 6 1 2 1

### System Response:

2005-11-18 11:00:27 EDT FORCE FAILOVER 6 1 2 1

If resiliency is not enabled for the trunk, the system response is

2005-11-18 11:00:27 EDT FORCE FAILOVER Failed, Resiliency not enabled.

If you do not enter the command from the primary controller, the system response is

2005-11-18 11:00:27 EDT FORCE FAILOVER Failed, must invoke from Primary Controller.

If the trunk is not connected to a T1/E1 Combo MMC, the system response is

2005-11-18 11:00:27 EDT FORCE FAILOVER Failed, T1E1 Combo Module required.
