Access Through The Maintenance Telephone - Nortel Meridian 1 Manual

Access through the maintenance telephone

A telephone functions as a maintenance telephone when you define the class
of service as MTA (maintenance set allowed) in the Multi-line Telephone
Administration program (LD 11). A maintenance telephone allows you to
send commands to the system through the following maintenance overlays:
LD 30, LD 32, LD 33, LD 34, LD 35, LD 36, LD 37, LD 38, LD 41, LD 42,
LD 43, LD 45, LD 46, LD 60, LD 61, LD 62.
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 3. 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 6
shows the translation from a terminal keyboard to a telephone dial pad.
Note: The Core Common Equipment Diagnostic Program (LD 135) and
Core I/O Diagnostic Program (LD 137) are among the overlays that
cannot be accessed through a maintenance telephone.
Note: To use the maintenance telephone, the peripheral equipment loop
for that telephone must be operating.
