Issue 4 May 2003 81555-233-767
Multimedia data conferencing (T.120)
through an ESM
The data conference is controlled by an adjunct device called an Expansion
Services Module (ESM). The ESM is used to terminate T.120 protocols [including
Generalized Conference Call (GCC), a protocol standard for data conference
control] and provide data conference control and data distribution. The
MultiMedia Interface circuit pack, TN787, is used to rate adapt T.120 data to/from
the ESM.
For more information on ESM, see Installation for Adjuncts and Peripherals for
Avaya™ Communication Manager, 555-233-116.
Multimedia hold, conference,
transfer, and drop
Station users have the ability to activate hold, conference, transfer, or drop on
multimedia calls. Multimedia endpoints and voice-only stations may participate in
the same conference.
Multimedia queuing with voice
announcement
When multimedia callers queue for an available member of a hunt group, they are
able to hear an audio announcement.
Paging and intercom
Code calling access
This feature allows attendants, users, and tie trunk users to page with coded chime
signals. This feature is helpful for users who are often away from their telephones
or at a location where a ringing telephone might be disturbing.
