# EDT CANCEL HANDOFF

## Qualifiers:

ALL

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

## Purpose:

Use this command to cancel the EDT Courtesy Handoff command and keep any resilient T1/E1 trunks circuits that have not already been handed off to the secondary on the primary controller.

After you enter this command on the primary controller

1. Any T1/E1 trunks circuits that have not already been handed off to the secondary remain on the primary controller.

2. Any T1/E1 circuits that have already been handed off to the secondary controller, remain on the secondary controller until they are sent back to the primary controller by the Programmed Failback or you force them back by entering the EDT Forced Failback command.

## Details:

- You must enter this command on the primary 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).

- Enter the EDT Show Resiliency command to check the resiliency status of the T1/E1 trunk circuits. Circuits that are in Courtesy Handoff mode are listed in "CHM" state.

- You can enter the EDT Forced Failback command to cancel the Courtesy Handoff command and immediately return all the circuits that have failed over to the secondary controller back to the primary controller.

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

- See the Resiliency Guidelines for instructions on how to install, configure, troubleshoot, and maintain T1/E1 trunk resiliency.

## Example:

### Entry: EDT CANCEL HANDOFF 6 1 2 1

### System Response:

2005-11-18 11:00:27 EDT CANCEL HANDOFF 6 1 2 1

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

2005-11-18 11:00:27 EDT CANCEL HANDOFF 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 CANCEL HANDOFF 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 CANCEL HANDOFF Failed, T1E1 Combo Module required.

If you enter the EDT Cancel Failback against the same circuits twice, the system response is

2005-11-18 11:00:27 EDT CANCEL HANDOFF: already cancelled.
