Msmwi Feature Applications; Privacy Release - Nortel Meridian SL-100 Reference Manual

In order to use the MSMWI feature, a primary terminal must have one of the
following features assigned to it:
All attempts to remove MWT or EMW from the primary terminal will be
blocked until all MSMWI assignments associated with that primary terminal
are removed from the corresponding secondary terminals.
The visual indication on the secondary terminals consists of a lit
liquid-crystal display (LCD) lamp associated with the MSMWI key. When
message waiting indication is turned on for the primary terminal, the LCD
lamp associated with the corresponding MSMWI key on the secondary
terminal(s) is turned on (lit in a steady state). When message waiting
indication is turned off for the primary terminal, the LCD lamp associated
with the corresponding MSMWI key on the secondary terminal is also
turned off.
The MSMWI feature does not provide any means of accessing messages left
against a primary terminal. It only provides a visual indication of such
messages. Existing methods for accessing messages are unaffected by this
feature, and may still be used.
Note: If the terminal datafilled with the MSMWI key set feature has a
light-emitting diode (LED), it will not be used in conjunction with this
feature.

MSMWI feature applications

A typical application of the MSMWI feature is a help desk. Indication of
messages left for a help desk is currently only provided on the help desk
terminal itself. With the MSMWI feature, help desk personnel will have a
visual indication of messages left for the help desk on their individual phone
sets, provided that each terminal is of a terminal type compatible with the
MSMWI feature.
Another application of the MSMWI feature is for an administrative position
with responsibility for several managers. The administrative position can
have several instances of the MSMWI key set feature assigned (one for each
manager for which the position is responsible).
