Although equipment such as single-line telephones, analog modems, and fax
machines do not have buttons, the system treats these as multiline telephones
with 34 buttons. In both Key and Behind Switch modes, the system assigns no
outside lines to this type of equipment. The system assigns two ICOM Ring
buttons to equipment connected to an 012 (T/R), 016 (T/R), or 008 OPT module;
or, for Release 7.0 and later systems, to a port programmed for tip/ring operation
on an 016 ETR or 412 LS-ID-ETR module. The system assigns an ICOM Ring
and an ICOM Voice button to every adjunct connected through an MFM. You must
remove the ICOM Voice button.
