The Automatic Line Management (ALM) feature of the 7401D or 7401 Plus voice
terminal automatically selects one of the two
virtual
call appearances when the
user goes off-hook either by the user’s lifting the handset (on the 7401D or the
7401 Plus voice terminal) or turning on the optional speakerphone adjunct (on the
7401 Plus voice terminal). ALM follows a hierarchical algorithm. From the user’s
point of view, the hierarchical order of actions which could take place is:
1. If either of the status lights of the virtual call appearances is flashing when
the user takes the telephone off-hook, the voice terminal will always pick-up
the “ringing” call. If both virtual call appearances are in the flashing state,
the voice terminal will select the call that was ringing for the longer period
of time.
2. If neither of the status lights is flashing, but one is winking or fluttering when
the telephone goes off-hook, the voice terminal will automatically “un-hold”
the held call. If both virtual call appearances are in the held state, the voice
terminal will select the call that was on hold for the longer period of time.
3. If neither of the status lights is flashing, winking, or fluttering, but one is
steady when the voice terminal goes off-hook, the voice terminal will
automatically bridge on to the busy appearance. If both virtual call
appearances are in the steady state, the voice terminal will choose the first
virtual call appearance. (A call appearance can be in the busy state due to
another party answering the call. This can occur in conjunction with such
features as coverage, bridging or pickup.)
4. Otherwise, no special action is taken; the voice terminal will pick up an idle
virtual call appearance as determined by the PBX.
