Maintenance
Access through the maintenance telephone
A telephone functions as a maintenance telephone when you define the
class-of-service as MTA (maintenance telephone allowed) in the Multi-line
Telephone Administration program (LD 11). A maintenance telephone
allows you to send commands to the system, but you can only use a subset of
the commands that can be entered from a system terminal.
You can test tones and outpulsing through the maintenance telephone.
Specific commands for those tests are given in the Tone and Digit Switch and
Digitone Receiver Diagnostic (LD 34).
To access the system using the maintenance telephone, see Procedure 2. To
enter commands, press the keys that correspond to the letters and numbers of
the command (for example, to enter LD 42 return, key in 53#42##). Table 2
shows the translation from a keyboard to a dial pad.
The following overlays (LDs) AREaccessible from amaintenance telephone:
30, 32, 33, 34, 35, 36, 37, 38, 41, 42, 43, 45, 46, 60, 61, and 62
The following overlays (LDs) ARE NOT accessible from a maintenance
telephone: 31, 40, 48, 77, 80, 92, 96, 135, 137
Note: To use the maintenance telephone, the loop for that telephone
must be operating.
