AT&T MERLIN LEGEND Release 3.1 System Planning Manual page 124

Assigning Telephone Buttons
Single-line telephones cannot have additional SA or SSA buttons.
However, single-line telephones connected through an 012, 016, or 008
OPT module can have SA buttons removed from them. Removing all but
one SA button from Single-line telephones will disable features such as
Transfer, Conference, and any other feature that requires more than one
SA button.
If you want the extension to receive outside calls on a specific line/trunk,
assign a personal line button; if you want the extensions to receive
outside calls on a line/trunk included in a pool, assign a Pool button. See
System Programming for instructions.
For adjuncts connected using an MFM, it is recommended that you change the
Button 2 assignment to SA Orig Only and remove the Button 3 assignment.
