CAS Backup Service
The CAS Backup Service provides for CAS attendant-seeking calls to terminate at an
extension number at the CAS branch location. This extension number may be assigned to an
attendant or a voice terminal user. The CAS backup position will have a CAS Backup button
and, when CAS Backup Service is active, the lamp at the CAS Backup button will light.
The CAS Backup Service can be activated:
Manually by the user at the CAS backup position.
When CAS Backup Service is manually activated, it can also be manually deactivated.
Automatically by the system when the RLTs are maintenance busy or are out of
service.
When the system activates CAS Backup Service, the system will also deactivate it
when the RLTs are available again. The user at the CAS backup position cannot
deactivate CAS Backup Service if it was activated by the system.
When CAS Backup Service is active, all attendant-seeking CAS calls for the branch location
will terminate at the backup position. The backup position can then extend or transfer calls
the same as any other incoming call.
To activate CAS Backup Service:

Press [CAS Backup]
Lamp associated with button lights.
