Access through the maintenance telephone
The Call Server can be accessed using a maintenance telephone.
Note: As the MG 1000T does not support line circuit cards,
maintenance telephones cannot access the MG 1000T.
A telephone functions as a maintenance telephone when the class-of-service
is defined as MTA (maintenance telephone allowed) in LD 11.
A maintenance telephone enables the user to send a subset of commands. The
maintenance telephone takes priority over a system terminal and will log the
terminal out.
Specific commands for testing tones and outpulsing through the maintenance
telephone are given in the Tone and Digit Switch and Digitone Receiver
Diagnostic (LD 34).
Specific commands for testing trunk connections through the maintenance
telephone are given in the Trunk Diagnostic (LD 36).
The following Maintenance Overlays are accessible from an IP Phone
operating as a maintenance telephone: 30, 32, 33, 34, 36, 37, 38, 42, 43, 45,
46, 60, and 62.
Note: The above maintenance overlay operations are supported on
IP Phones except for the Tone and Digit Switch (TDS) commands of LD
34 and TONE commands of LD 46.
To use the maintenance telephone, the Terminal Number (TN) for that
telephone must be operating.
To access the system using the maintenance telephone, a Special Service
Prefix (SPRE) code (defined in the customer data block) is entered followed
by "91" (see Procedure 2 on
