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

resources. When the service link is disconnected it does not tie up any 
resources. The Service Link Mode can be administered as either 
‘as-needed’ or ‘permanent’ as described below:
— As-Needed
 - Most non-call center multimedia users will be 
administered with this service link mode. The as-needed mode 
provides the Enhanced multimedia complex with a connected 
service link whenever a multimedia call is answered by the station 
and for a period of 10 seconds after the last multimedia call on the 
station has been disconnected. Having the service link stay 
connected for 10 seconds allows a user to disconnect a multimedia 
call and then make another multimedia call without having to wait 
for the service link to disconnect and re-establish.
—Permanent
 - Multimedia call center agents and other users who are 
constantly making or receiving multimedia calls may want to be 
administered with this service link mode. The permanent mode 
service link will be connected during the station’s first multimedia 
call and will remain in a connected state until the user disconnects 
from their PC’s multimedia application or the DEFINITY ECS 
switch restarts. This provides a multimedia user with a much quicker 
video cut-through when answering a multimedia call from another 
permanent mode station or a multimedia call that has been early 
answered.
nMultimedia Mode — There are two multimedia modes, Basic and 
Enhanced, as described below:
—Basic
 — A Basic multimedia complex consists of a BRI-connected 
multimedia-equipped PC and a non-BRI-connected multifunction 
telephone set. When in Basic mode, users place voice calls at the 
multifunction telephone and multimedia calls from the multimedia 
equipped PC. Voice calls will be answered at the multifunction 
telephone and multimedia calls will alert first at the PC and if 
unanswered will next alert at the voice station if it is administered 
with H.320 = y. A Basic mode complex has limited multimedia 
feature capability as described in ‘‘
Basic Mode Operation’’ on page 
233).
—Enhanced
 — An Enhanced multimedia complex consists of a 
BRI-connected multimedia-equipped PC and a non-BRI-connected 
multifunction telephone. The Enhanced mode station acts as though 
the PC were directly connected to the multifunction telephone; the 
service link provides the actual connection between DEFINITY 
ECS and the PC. Thus, voice and multimedia calls are originated 
and received at the telephone set. Voice and multimedia call status 
are also displayed at the telephone set. An Enhanced mode station 
allows multimedia calls to take full advantage of most call control 
features as described in ‘‘
Enhanced Mode Operation’’ on page 234.

nMultimedia Early Answer — Valid entries are y and n (default). This field 
lets you set this phone for early answer of multimedia calls. The system 
will answer the incoming multimedia call on behalf of the station and 
proceed to establish the H.320 protocol. After audio path has been 
established to the caller, the call will then alert at the voice station. The 
station may then answer by going off-hook and will have immediate audio 
path. No hourglass tone will be heard by the answering party (see 
‘‘
Hourglass Tone’’ on page 255).
Example: An administrative assistant who does not have a multimedia PC, 
but may get multimedia mode calls from forwarding or coverage, may want 
to set the H.320 flag to y and the early answer flag to y on their voice 
station. This allows any multimedia call to be presented to the station with 
immediate voice path rather than hourglass tone. The answered call could 
then be transferred as voice to voice mail or transferred as multimedia to a 
user equipped with a multimedia endpoint.
Multimedia Buttons
There are six new multimedia specific buttons that may be added to a voice 
station. Most of them may be placed on any voice station, whether it is part of a 
Basic multimedia complex, an Enhanced multimedia complex or not part of any 
multimedia complex. Two feature buttons, mm-basic and mm-pcaudio, may only 
be placed on stations which are part of an Enhanced multimedia complex.
All of the multimedia specific feature buttons have a corresponding feature access 
code except mm-pcaudio and mm-cfwd. 
nThe mm-pcaudio feature can only be used via button. 
nThe mm-cfwd button may be replaced by the standard “call forward” FAC 
followed by the “multimedia call” FAC.
nmm-call — This button may exist on any voice station. Most multimedia 
enabled users will want an mm-call button. This button (or it’s 
corresponding FAC) must be used to indicate that the user is placing a 
multimedia mode call. To place a multimedia mode call the user would go 
off-hook, select an idle call appearance, and press the mm-call button 
followed by the destination extension digits. If the user has a speakerphone 
they can simply press the mm-call button, which preselects an idle call 
appearance, followed by the destination extension digits.
The mm-call button lamp lights when you press this button during call 
origination. The lamp also lights to indicate that the selected call 
appearance is a multimedia mode call.

nmm-basic — This button is only allowed on the voice station of a 
multimedia complex. The mm-basic button toggles a station between Basic 
and Enhanced modes. This button can NOT be used to change the station’s 
multimedia mode when the station has an active multimedia call 
appearance.
Toggling between Basic and Enhanced mode changes the station’s 
administered Multimedia mode. When in Basic mode this field on the 
station form will show basic. When in Enhanced mode this field on the 
station form will show enhanced. The current station Multimedia mode 
will be saved to translation when a save translation command is 
executed.
nmm-pcaudio — This button only works for an Enhanced multimedia 
complex voice station. When originating or receiving a multimedia call, the 
audio path is connected to the voice station’s handset or speakerphone 
device. The mm-pcaudio button allows a user to switch the audio portion of 
any call to their PC’s audio input/output device (if available). To switch the 
audio path to the PC while active on a call, the user presses the 
mm-pcaudio button (if off-hook you may now hang up the handset). The 
mm-pcaudio button’s status lamp will light up when the button is pushed to 
move the audio path to the PC and remain lit while the audio path is at the 
PC device. 
NOTE:
If you are on a voice only call, the voice path will switch to the PC 
device but you will get muted or loopback video depending on the 
multimedia endpoint software.
A user may simply go off-hook on their voice station or press the 
speakerphone button to move the audio path of a multimedia call from the 
PC back to the voice station. Pressing the mm-pcaudio button while the 
status lamp is lit and the voice station’s handset is on-hook will disconnect 
the user from the active call.
nmm-datacnf — Pressing the mm-datacnf button from any voice station 
that is participating in a multimedia call will light the status lamp and alert 
the DEFINITY ECS that you want to enable T.120 data collaboration with 
the other parties on the call. The button status lamp will also light for other 
participants in the multimedia call who have mm-datacnf buttons. 
Pressing this button from the voice station that enabled data collaboration 
on a multimedia mode call will deactivate the data session and revert to a 
voice and video call. If you are participating on a multimedia call with data 
collaboration, but did not initiate the data collaboration, and you press this 
button, the status lamp led will flash momentarily and the T.120 data

services will not be terminated, (only the station that activated the 
collaboration session can deactivate it). This button only works for stations 
connected to a DEFINITY ECS equipped with an ESM adjunct.
nmm-cfwd — The mm-cfwd button allows a user to indicate that 
multimedia mode calls will be forwarded as multimedia mode calls to a 
specific forwarded-to destination. If voice call forwarding is active and 
multimedia call forwarding is not active then multimedia calls going off of 
the DEFINITY ECS switch will be forwarded as voice only calls.
The mm-cfwd button status lamp will be lit to indicate that multimedia call 
forwarding is activated. Pressing the mm-cfwd button when the lamp is lit 
will deactivate multimedia call forwarding.
Note - pressing the mm-cfwd button is the same as dialing the regular 
call-fwd FAC followed by the mm-call button or FAC followed by the 
desired forwarded-to extension digits.
nmm-multinbr — The mm-multinbr call button is similar to the mm-call 
button. It allows origination of a multimedia call from any voice station. It 
is used when the destination being dialed requires a different address for 
each of the 2 B-channels. An example of this is Central Office provided 
ISDN-BRI. This type of BRI line is provisioned with separate listed 
directory numbers for each B-channel. In order to make a 2B multimedia 
call to such a device, two sets of address must be entered. 
Originating a multimedia call with the mm-multinbr button will originate a 
call according to the Default Multimedia Parameters selected on the 
System Parameters Features form. This default parameter will be either 
2x56 or 2x64. The bearer capability of the multimedia calls will either be 
56K or 64K and the bandwidth will be 2B channels.
