Feature Description
MMCH’s two levels of functionality for a multimedia complex, Basic and 
Enhanced mode, are enabled either by switch administration or by an mm-basic 
feature button or FAC.
Basic Mode Operation
In Basic Mode:
nAll voice-only calls originate at the voice station.
nAll multimedia calls originate with the H.320 DVC system. 
nAll incoming voice calls attempt to alert at the voice station and receive all 
standard voice call treatment.
nAll incoming H.320 multimedia calls attempt to alert on the H.320 DVC 
system initially. If answered, a 2-way video call will result. The Basic 
multimedia complex voice station will not be involved in the call in any 
way.
If the H.320 multimedia call is not answered at the H.320 DVC system and 
the Basic multimedia complex voice station has the H.320 field 
administered to “y”, the call will:
— timeout at the DVC system
— alert at the associated voice station set as a voice-only call
— receive all standard voice call treatment.
nCall control depends on what type of call is being originated. 
— Video is received and controlled at the PC. 
— Voice is received and controlled at the telephone set.
nThe voice station of a Basic multimedia complex must manually add their 
multimedia endpoint to a multimedia conference. There is limited support 
for multimedia feature interactions. A specific set of voice features work 
for multimedia calls.
nService Links are not used by Basic mode complexes.
nA single number may be used to reach the Basic multimedia complex for 
voice or H.320 multimedia calls.

Enhanced Mode Operation
The Enhanced multimedia complex provides a much more tightly coupled 
integration of the complex voice station and H.320 DVC system. In Enhanced 
Mode:
nBoth multimedia and voice calls must originate at the telephone set.
nVoice and multimedia calls can be controlled at the telephone set.
nConferencing is spontaneous and established just like a voice-only 
conference call.
nThere is extensive support for multimedia feature interaction. Most voice 
features work the same for multimedia calls.
nService Links can be either “permanent” or “as-needed.”
Physical Installation
The physical components necessary to utilize MMCH capabilities include:
nH.320 DVC systems that are BRI connected to the DEFINITY ECS.
nNon-BRI multifunction telephones.
nDEFINITY TN787 MultiMedia Interface (MMI) and TN788 Voice 
Conditioner (VC) boards.
nA T.120 Enhanced Services Module (ESM) server (necessary only if you 
plan to do T.210 data collaboration). Connectivity of the ESM requires an 
additional TN787 along with a TN2207 DS1 circuit pack.
Dual Port Desktop
Both Basic and Enhanced multimedia complexes are dual-port desktops that 
consist of:
na BRI-connected multimedia-equipped PC that supports the H.320 protocol
na non-BRI-connected multifunction telephone set. 
The PC and the multifunction telephone are individually wired to the DEFINITY 
ECS. These two pieces of equipment can be administratively associated to form a 
Basic or ENHANCED multimedia complex 
MMCH works with any H.320 system that is fully H.320 compliant and operates 
at the 2B or 128K rate. 
NOTE:
If you intend to share applications among users or whiteboard capabilities, 
the endpoint software you choose must also support the T.120 protocol.

The following endpoint-software packages have been tested:
nPictureTel PCS 50 & PCS 100, Release 1.6T
nProshare 2.0a, 2.1
nZydacron Z250 Ver. 2.02, Z350 Ver. 1.2 (With Netmeeting 2.0)
MMI & VC hardware
The MMCH feature requires the use of two additional circuit packs:
nMulti Media Interface (MMI) TN787J.
nVoice Conditioner (VC) TN788B.
The TN787 and TN788 are service circuit packs. The TN787 supports 
simultaneous operation of 16 2B H.320 calls. The TN788 supports the voice 
processing for 4 H.320 endpoints. 
nThese service circuit packs may be located in any Port Network. 
nThese packs do not require any translations as part of their implementation. 
nThe MMI and VC circuit packs are resource circuit packs akin to the Tone 
Detector circuit packs. 
nThese circuit packs require no switch administration and may be located in 
multiple port networks.
nSpecific provisioning guidelines for the number and placement of these 
packs can be found by calling the Lucent Technical Support Center (TSC) 
at (303) 850 - 8187. 
T.120 Data Collaboration Server
The Expansion Services Module (ESM) provides T.120 data collaboration 
capability on a MMCH multipoint H.320 video conference. 
nEach person in the conference who wants to participate in the data 
collaboration session, must have a personal computer with an H.320 video 
application that supports the T.120 protocol. 
nThe DEFINITY ECS must have an ESM installed.

Planning for MMCH
The following are some of the tasks you perform in planning and administering 
MMCH.
Planning the system
This is a list of questions to help you use DEFINITY ECS for multimedia. 
nHow many MMCH users are you going to have? 
nHow many multimedia calls do you expect to have at any given time?
With the information above you can determine how many Voice Conditioner (VC) 
and Multimedia Interface (MMI) circuit packs you need. 
nWill users need data collaboration capabilities? If so, you need to install the 
Expansion Service Module (ESM).
nWhich stations, hunt groups or vectors need early answer? 
nDo you have ISDN-PRI trunks? It is possible to use separate DS1 trunks 
for data, but ISDN-PRI trunks are recommended.
Installation checklist
1. Purchase MMCH right-to-use.
2.Lucent Technologies — enable MMCH on System Parameters 
Customer-Options screen.
3. Administer default multimedia outgoing trunk parameter selection on the 
Feature-Related System-Parameters Features screen.

Station screen 
After you have administered the BRI data module, use the Station screen to 
associate it with a voice station to screen a multimedia complex. This is a 
one-to-one relationship: you can administer only one station and one data 
endpoint per multimedia complex. Neither the voice station, nor the data endpoint 
can be a member of another multimedia complex.
NOTE:
A BRI station cannot be part of a multimedia complex.
nH.320 Conversion — Valid entries are y and n (default). This field is 
optional for non-multimedia complex voice stations and for Basic 
multimedia complex voice stations. It is mandatory for Enhanced 
multimedia complex voice stations. Because the system can only handle a 
limited number of conversion calls, you may need to limit the number of 
telephones with H.320 conversion. Enhanced multimedia complexes must 
have this flag set to y.
For non-multimedia complex voice stations, setting this field to y allows 
H.320 calls to convert to voice and alert at the stand-alone voice station. If 
the call is unanswered at the voice station, the call will follow standard 
voice treatment. Any subsequent station that is reached in the routing of 
this call, that is, coverage points, forwarded destinations, call pickup 
members, and so forth, do not need to have the H.320 field enabled. The 
H.320 field is only needed at the 
first station that may receive the H.320 
call. 
For Basic multimedia complex voice stations, setting this field to y allows 
H.320 calls to convert to voice and alert at the Basic multimedia complex 
voice station 
after an attempt has been made to offer the call to the H.320 
DVC system. If the call is unanswered at the H.320 DVC system, the call 
will alert at the voice station after 5 seconds or after the administered 
number of rings as specified in the voice station’s coverage path. If the call 
is unanswered at the voice station, the call will follow standard voice 
treatment. Any subsequent station that is reached in the routing of this call, 
that is, coverage points, forwarded destinations, call pickup members, and 
so forth, do not need to have the H.320 field enabled. The H.320 field is 
only needed at the 
first station that may receive the H.320 call. 
nService Link Mode — The service link is the combined hardware and 
software multimedia connection between an Enhanced mode complex’s 
H.320 DVC system and the DEFINITY ECS which terminates the H.320 
protocol. A service link is never used by a Basic mode complex H.320 
DVC system. Connecting a service link will take several seconds. When 
the service link is connected, it uses MMI, VC and system timeslot
