6. To end the data collaboration session and retain the voice/video conference, 
the station that selected the mm-datacnf button or FAC may press the 
mm-datacnf button or hit transfer and dial the mm-datacnf deactivation 
FA C .
NOTE:
Currently, many endpoints do not respond correctly to ending the 
data collaboration session and retaining voice/video. Some H.320 
DVC systems drop the entire call. It is recommended that once T.120 
data sharing has been enabled for a conference, that it remain active 
for the duration of the conference call. When all endpoints have 
dropped from the call, the T.120 resources will be released.
Joining a multimedia conference after T.120 data sharing has been enabled.  
If a multimedia conference with T.120 data sharing is already active and it is 
desired to conference in a new video endpoint, the new video endpoint can be 
conferenced into the existing call. The new endpoint will be allowed into the data 
conference if there exists sufficient ESM resources for the new endpoint. The new 
endpoint will get voice/video and data sharing if the new endpoint supports the 
data rate chosen by the system when T.120 data collaboration was activated. If the 
endpoint does not support the pre-existing data rate, the new endpoint will only 
receive voice and video.
Activating HOLD while on a T.120 data collaboration conference. 
If an Enhanced multimedia complex is active on a multimedia call and the call has 
activated T.120 data collaboration, the user should be receiving voice/video and 
data. If the station places this existing call on hold, audio and video will be 
disconnected for the current call. The data collaboration portion of the call will 
remain intact and unaffected. While this T.120 data conference is on hold, the user 
will only be allowed to receive audio on all other call appearances. Thus a user is 
limited to one call appearance that has T.120 data collaboration active.
Single switch data collaboration.  When all parties involved in data 
collaboration conference are located on the same physical DEFINITY ECS, there 
is no restriction on the type of user. The parties may be any combination of 
Enhanced multimedia complexes, Basic multimedia complexes or stand-alone 
H.320 DVC systems.

Multi- switch data collaboration.  When all parties involved in data 
collaboration conference are not located on the same physical DEFINITY ECS, 
the parties located on the DEFINITY ECS hosting the data conference (i.e. the 
switch that activated mm-datacnf) may be any combination of Enhanced 
multimedia complexes, Basic multimedia complexes or stand-alone H.320 DVC 
systems. 
NOTE:
All parties on remote switches must not be Enhanced multimedia 
complexes. They must be Basic multimedia complexes or stand-alone H.320 
DVC systems. 
Prior to originating or receiving a multimedia mode call, the mm-basic feature 
button or feature access code can be used to dynamically change an Enhanced 
mode complex into a Basic mode complex and back again.
Voice station audio vs. H.320 DVC system audio
When an Enhanced mode complex originates or receives a voice or multimedia 
call, the call is originated with the station handset or answered with the station 
handset. The audio path will be through the handset. If the user’s H.320 DVC 
system has speakers and a microphone, the user may wish to use the H.320 DVC 
system for audio in much the same manner as a built-in or separate telephone 
speakerphone. The user can move the station’s audio to the H.320 DVC system by 
selecting an 
mm-pcaudio feature button on the voice station. There is no feature 
access code for this function.
The mm-pcaudio feature button works very much like a speakerphone on/off 
button. If the station is off-hook and selects mm-pcaudio, audio is directed to the 
PC DVC system. The switch-hook may be placed on-hook. If the handset is taken 
off-hook, the audio moves back to the handset. If the mm-pcaudio button is 
selected while audio is already on the DVC system and the handset is on-hook, 
this acts as a speakerphone off action and disconnects the current call.
The mm-pcaudio feature button may be used for voice as well as multimedia calls. 
If the mm-pcaudio feature button is selected while on a voice only call, the DVC 
system is alerted and brought into the call. No video will be transmitted or 
displayed. Audio will be directed through the PC DVC system.

Switching between Basic and Enhanced modes
There may exist occasions when an Enhanced mode complex needs to switch to 
Basic mode operation temporarily. One example is when a user wishes to make a 
direct point to point multimedia call originated directly from the H.320 DVC. 
Basic mode operation allows this functionality at the expense of losing 
multimedia call handling capabilities (i.e. hold/xfer/conf). To switch from 
Enhanced mode to Basic mode, the station may either select a mm-basic feature 
button or dial the mm-basic feature access code. Both of these actions are valid 
only if the Enhanced mode station has no multimedia calls active. 
When in Basic mode, the status lamp for the mm-basic button, if present, will be 
on solid. The mm-basic feature button acts as a toggle. If the status lamp is on, 
when the button is selected, the lamp will go off and the station will return to 
Enhanced mode. The mm-enhanced feature access code will set the state of the 
station back to Enhanced. Switching to Enhanced mode is only valid if the 
associated H.320 DVC system is idle. 
NOTE:
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.
Forwarding of voice and multimedia calls
The Enhanced multimedia mode complex voice station may use the existing 
standard call forwarding mechanisms to activate forwarding for voice calls. If the 
forwarding destination is on the same switch then this will also forward 
multimedia calls as multimedia calls to the destination. If the forwarding 
destination is off switch, multimedia calls will forward off switch as voice only 
calls. This is appropriate when the user will be at a location that is not able to 
receive multimedia calls.
To forward multimedia calls off switch as multimedia calls, the user must activate 
multimedia call forwarding. This may be done with an mm-cfwd button or feature 
access code. The user may also activate standard voice call forwarding and select 
the mm-call button prior to entering the forwarding address.

Coverage
Multimedia calls to an Enhanced mode complex are subject to the same coverage 
criteria as voice calls and follow the coverage path administered for the voice 
station of the Enhanced multimedia mode complex.
If a plain voice station or a Basic mode complex is the covering party, the 
answering voice station will receive audio only. If all voice stations in the 
coverage path have the station form Early Answer field set to n and the originator 
of the multimedia call was not a local Enhanced mode complex, the answering 
station will hear hourglass tone.
If an Enhanced mode complex is the covering party, the answering voice station 
will receive voice and video. If all voice stations in the coverage path have the 
station form Early Answer field set to n and the originator of the multimedia call 
was not a local Enhanced mode complex, the answering station will hear 
hourglass tone.
Multimedia calls and off-net call coverage. If the principal station’s coverage 
path include a remote coverage point, the multimedia call will cover off-switch as 
voice only. If the call is unanswered off-switch and proceeds to the next coverage 
point on-switch, the multimedia nature of the call is preserved. 
Multimedia calls and coverage to voice mail.  Voice mail systems such as 
AUDIX are typically the last point in a coverage path and are usually 
implemented as a hunt group. In order to guarantee that the originator of an H.320 
multimedia call hears the voice mail greeting, the hunt group that defines the list 
of voice mail ports should have the Early Answer field on the hunt group set to y. 
This field will have no effect on voice calls to the voice mail system.
Hunt Groups using Enhanced Mode Complexes
When creating hunt groups with Enhanced multimedia mode complexes, only the 
station extension should ever be entered as a hunt group member. Any hunt group 
or ACD skill can include the voice station of an Enhanced multimedia complex as 
a member. The data extension of an Enhanced mode complex should never be 
entered as any hunt group member. A hunt group or skill may have a mix of 
members that are stand-alone stations and Enhanced mode complex stations. In 
order to guarantee that all members of the hunt group or skill can receive voice or 
multimedia calls, all members should have the H.320 field on the station form set 
to y. Simple voice stations will receive voice only. Enhanced mode stations will 
receive voice and video.
The MM Early Answer field (on the Hunt Group form) tells the system to answer 
an incoming multimedia call and establish audio before it reaches the first 
member of the hunt group. Thus, when the talk path is established, the caller is 
able to speak with an agent immediately.

Other considerations. CMS measurements may indicate unusually slow ASA, 
because of the time required for the system to establish early-answer before 
offering the call to an agent. 
Call association (routing). Typically incoming voice calls consist of 2 B-channel 
calls to the same address, to provide greater bandwidth and better video 
resolution. DEFINITY ECS attempts to correctly pair up incoming calls and offer 
them as a unit to a single agent. MMCH uses call association to route both calls to 
the extension that answered the first call, regardless of how the call was routed 
internally.
Two 56K/64K data calls with the same calling party number to the same 
destination number are considered to be associated. The system makes every 
attempt to route both calls of a 2-channel call to the same answering party. If the 
first call terminates at a member of a hunt group, the second call does not have to 
hunt, but goes directly to the same member. 
In order for 2B multimedia calls to be correctly given to a single agent, incoming 
calls to the hunt group must have ANI information. The ANI information may be 
in the form of ISDN calling party number or DCS calling party number. 
Multimedia calls made on the same switch as the hunt group are easily associated. 
If multimedia calls into a hunt group have insufficient ANI information (i.e. all 
calls from switch X to switch Y include the LDN for switch X), then as the 
volume of calls increases the number of mis-associated calls will increase. If 
multimedia calls into a hunt group have no ANI information, the switch will never 
associate pairs of calls and all calls will be treated independently and routed to 
separate agents. This is not a recommended configuration.
Multimedia vectors. Very often, calls are routed to hunt groups or skills via a 
vector. The existing VDNs and vectors which exist for routing voice calls can be 
used to route multimedia calls. 
In order to use a vector for multimedia calls, you must set the Multimedia field on 
the vector form to y. This field has no effect on voice calls routing through the 
vector. This field will cause multimedia calls routed through the vector to receive 
early answer treatment prior to processing the vector steps. This provides a talk 
path to the caller for announcements or immediate conversation with an agent. 
NOTE:
Vectors which have the Multimedia field set must eventually route to 
hunt groups, skills or numbers which are voice extensions. A vector 
with the multimedia field set to y should never be set up to route to a 
hunt group or number which is a data extension.

Interactions
Interactions are listed here only if the operation is different from standard. 
nAdministered Connections
An Enhanced multimedia complex voice station may serve as the 
origination point or destination of an administered connection. If the 
Multimedia call feature access code is included in the administration of the 
administered connection, this will result in a video AC.
An Enhanced multimedia complex H.320 DVC system may not serve as 
the origination point of an administered connection.
nX-porting
You cannot use X in the port field when administering a data module or the 
data endpoint in a multimedia complex. However, you can use this to 
administer the telephone. 
nBridged Appearances
Enhanced multimedia complex voice station users can bridge onto a call if 
the user has a bridged appearance. If the bridged appearance is for a 
multimedia call, selecting the bridged appearance will result in a 
multimedia call.
nCall Detail Recording
Each channel of a 2-channel multimedia call generates a separate CDR 
record that is tagged as data. 
nCall forwarding 
Users cannot forward calls from a multimedia complex using multi-number 
dialing, either by mm-multnmbr button or feature access code. 
nCall Park
Any station can park a multimedia call, and unpark the call from another 
telephone. If a multimedia call is unparked by an Enhanced mode complex 
station, a multimedia call will result. Users cannot park or unpark calls 
using multimedia endpoints. 
nCall Pickup
Any member of a pickup group can answer a multimedia call after the call 
has begun alerting at a station call appearance. If the station picking up the 
call is an Enhanced mode complex station and the call is multimedia, a 
multimedia call will result. This is true for standard or directed call pickup. 
nConsult
After a multimedia call has been answered, consult may be used when 
transferring or conferencing the call.

nCOR/COS
The Class of Restriction and Class of Service for a multimedia call 
originated from an Enhanced multimedia complex are those of the voice 
station in the complex.
nData Call Setup
An Enhanced mode multimedia H.320 DVC system may not originate calls 
from the DVC system. All calls, both voice or video are originated from the 
voice station.
nData Hotline 
An Enhanced multimedia complex H.320 DVC endpoint may not be used 
to originate a call for hotline dialing. In order to setup a video hotline 
function with an Enhanced mode complex, the hotline number 
administered for the voice station should include the Multimedia call 
feature access code.
nData Trunk Groups
Data trunk groups may be used to carry H.320 calls of a fixed 
(administered) bearer capability. 
nISDN 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 channels to the correct destination 
device. ISDN also provides the bearer capability on a call by call basis that 
can be used to distinguish voice calls from multimedia calls.
nNight Service
Incoming H.320 calls follow established night-service processing for data 
calls. 
nRemote Access
The switch does not prevent Enhanced multimedia complexes from 
attempting to use remote access. However, these endpoints will most likely 
not be able to dial the necessary codes. 
nStation Hunting 
Multimedia calls to Enhanced mode complex voice stations that have an 
extension administered in the hunt-to-station field hunt based on 
established hunting criteria. If the hunt-to-station is also an Enhanced mode 
complex station, a multimedia call will result when the call is answered.

nTerminating Extension Groups
A multimedia call to a TEG may be answered by any member of the TEG. 
If the member answering the call is an Enhanced mode complex station, a 
multimedia call will result.
nTelephone Display
Display information for calls to or from an Enhanced multimedia complex 
contains the display information associated with the voice station.
Troubleshooting
If one channel of a 2 B-channel call goes down, your choices are to continue with 
reduced transmission quality, or to hang up the call and start over. It is not possible 
to re-establish the second channel while the call is still active. 
If you cannot share data with others, it may be that both parties do not have the 
same endpoint software. This is true for some data collaboration, but most 
whiteboard and file transfer software implementations are compatible.
Monitoring MMCH
This section briefly discusses some of the commands you can use to monitor 
multimedia complexes and conferences. DEFINITY ECS Maintenance for R7si

The 
list multimedia endpoints command shows you all the multimedia data 
modules that exist in your system, and their associated telephones, if any. The

Considerations
Each channel of a 2-channel BRI call takes one port on an MMI circuit pack. This 
alone limits the number of multimedia calls your system can handle. In addition, 
each conference takes one port on a voice-conditioner circuit pack. 
Also, there is a limit to the number of conversion calls that the system can handle 
simultaneously. If you experience traffic problems after installing multimedia, 
you may want to lower the number of stations that use H.320 conversion.
