Factory-Set Assignment, Analog Multiline Telephones - AT&T MERLIN LEGEND Release 3.1 System Planning Manual

Assigning Telephone Buttons
Although equipment such as single-line telephones, answering machines, and
fax machines do not have buttons, the system treats these as multiline
telephones with 34 buttons.
The system assigns one SA Ring, one SA Voice, and one SA Orig Only button
to every adjunct connected through an MFM to an MLX telephone. For
equipment connected to an 012, 016, or 008 OPT module, the system assigns
two SA Ring buttons and one SA Orig Only button.
