atmtest Test Requirements

atmtest can only be selected when the Intervention mode is enabled since it requires a loopback connector for external loopback testing. While Intervention mode is enabled, atmtest and nettest are both available as default selections, however, you must deselect nettest when testing the ATM device.

Bring the ATM interface down to make sure that the interface is in offline mode before running atmtest.

Do not run nettest while running atmtest.

The external optical loopback test requires a 62.5 micron cable.
