ISDN Trunk Groups. Lucent Technologies highly recommends that you use
ISDN trunks for multimedia calls. ISDN PRI trunks allow complete 1-number
access for an Enhanced multimedia complex. ANI provided over PRI trunks
allows correct routing of multiple bearer chan nels to the correct destination
device. ISDN also provides the bearer capability on a call by call basis which can
be used to distinguish voice calls from multimedia calls.
Malicious Call Trace. If a malicious call terminates at a Basic mult imedia
complex endpoint, the user can dial the feature access code from the telephone to
activate malicious call trace, followed by the extension of the m ultimedia
endpoint. If the user does not dial the multimedia extension, MCT traces any call
held on the telephone.
Message Waiting. Message Waiting indication is handled at the telephone.
Because H.320 calls are converted to vo ice bef ore g oin g to co ve ra ge, al l mes sages
are voice only.
Night Service. Incoming Basic mode data calls follow established night-service
processing for data calls.
Remote Access. The switch does not prevent Basic multimedia complexes from
attempting to use remote access. However, these Basic mode endpoints will most
likely not be able to dial the necessary codes.
Station Hunting . Basic mode data calls to endpoints that have an extension
administered in the hunt-to-station field hunt based on establis hed hunting cr iteria.
The call is converted to voice before station hunting.
Tenant Partitioning. Permission to make multimedia calls or add parties of any
type to a conference is subject to standard tenant-partitioning restrictions.
Terminating Extension Groups. Basic mode data calls to a TEG are con ver ted to
voice and can terminate only at a voice endpoint. Effectively, DEFINITY ECS
treats the multimedia-complex extension as a voice-only endpoint.
Telephone Display. Display information for calls to or from a Basic multimedia
complex contains the 1-number.
Enhanced Mode MM complex
The Enhanced multimedia complex provides a much greater unified and
integrated interface for control of voice and multi media calls. The multifunction
voice station is used to control all calls, whether voice or multimedia. The H.320
desktop video system is used to present the video stream, data stream and
(optionally) audio stream to the user. The H.320 desktop video system is
not
used
for call control. The Enhanced multimedia complex allows the multifunction
