remote device remains disconnected from the local device after the self-test.
A unique manufacturing number (maximum 8 numeric characters) found on the device.
This is a required field for remote dial devices.
An additional capability for DDD NIMs. This feature permits an extra dial line to be
connected to a COMSPHERE 3000 Series Carrier. It can be used for NIMs or as a backup
