Loop Keys Uniquely programmed Programmable Function Keys that provide an
appearance for outside lines (trunks) not assigned to a line key. There are
two types of Loop Keys: Switched Loop and Fixed Loop. For incoming
calls, both Switched Loop and Fixed Loop Keys provide an appearance
for any trunk not assigned to a line key. For outgoing calls, Switched
Loop Keys simplify access to trunk groups. Fixed Loop keys provide
access to a specific trunk group.

Loop Keys on page 59.
Meet-Me Conference A “telephone meeting” an extension user sets up with their co-workers at
one of the two predefined Meet-Me Conference locations. The number
of people that can join the Conference is limited only by the system’s
Conference circuit capacity.

unanswered keyset requesting a return call. Message Waiting is only
available in systems that don’t have Voice Mail installed.

microphone at any time.
