Lines
Behind Switch Mode Only
Prime Line button - used to access the host system’s pool of outside lines. To
call another person connected to the host system, the user dials the host system
extension number assigned to that person. To access outside lines, the user
dials a dial-out code (usually a 9), and the host system selects an available
outside line from its pool.
The system is factory set to assign certain kinds of line buttons depending on
the type of equipment and the mode of operation:
■ In the Key mode, the system assigns an IntercomRing button, an Intercom
Voice button, and the first eight outside lines connected to the control unit to
every non-operator multiline telephone
■ In the Behind Switch mode, the system assigns an Intercom Voice button,
and Intercom Ring button and one Prime Line button to every non-operator
multiline telephone.
■ For either mode, the line assignment is the same for both analog and
digital/lSDN (MLX) telephones.
