The maintenance software for Emergency Transfer monitors the position of the Emergency Transfer switch media modules. It does not monitor whether the system is actually in Emergency Transfer.

Emergency Transfer (ET) provides the ability to connect designated analog phones to CO trunks when the switch cannot provide minimal telephone service.

Emergency Transfer is automatically controlled by the system or can be manually controlled via the Emergency Transfer switch located on the Maintenance media module. A manual ON position up generates a Major alarm. A manual OFF position down generates a Warning alarm. Unless a technician is currently working on the system, the switch should be left in the auto position.
