Telephone Programming
The following describes how to program features on MLX and analog mutliline
telephones. Since Personal Speed Dial is the only feature that single-line
telephone users can program, general programming instructions for single-line
telephones are not provided.
NOTE:
Features cannot be programmed on QCCs in system operator positions.
Features assigned to these consoles are fixed and cannot be changed.
Programming Methods
Telephones can be programmed by dialing programming codes or, on MLX
display phones, selecting features from the display. An analog multiline
telephone cannot be programmed by selecting features from the display.
To program a telephone, first enter programming mode:
On analog multiline telephones, slide the Test/Program (T/P) switch on
the side of the telephone to P, or lift the handset, or press Speakerphone
and dial #00.
On MLX-10 telephones, press the Feature button and dial 00.
