Station Hunting . Basic mode data calls to endpoints that have an extension 
administered in the hunt-to-station field hunt based on established hunting 
criteria. 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 converted 
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 multimedia 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 
voice station to handle voice or multimedia calls in an almost identical manner. 
Each call appearance on the voice station may represent a voice or multimedia 
call, allowing multiple voice or multimedia calls to be present simultaneously on 
the station. The user may manage the separate call appearances without regard to 
the voice or multimedia nature of the specific call. The standard 
HOLD/TRANSFER/CONFERENCE/DROP actions may be applied to any call 
without regard to the voice or multimedia nature of the call.
1-number access
1-number access permits originating users to make voice or multimedia calls to an 
Enhanced multimedia complex by dialing the same number for either type of call. 
The number may be the voice station extension or the data module extension. If 
the incoming call is a voice call, DEFINITY ECS alerts the station of an incoming 
voice call. If the incoming call is 56K or 64K data call, DEFINITY ECS 
recognizes it as a multimedia call and inserts resources to terminate the H.320 
protocol and then alerts the voice station with a multimedia call. 
Calls originating on the same switch as the Enhanced mode complex destination 
may always use 1-number access for voice or video. In order to take advantage of 
1-number access for calls originating from a remote location, the incoming calls 
must arrive over ISDN-PRI trunks. If the system is setup with separate non-PRI 
digital facilities for data, multimedia calls must be made to the data extension of 
the Enhanced mode complex.

AVD (Alternate voice/data) trunk groups cannot be used to provide 1-number 
access with MMCH. If the AVD trunk group has a BCC of 0, all calls arriving 
over the AVD trunk to the Basic mode complex will be assumed to be voice calls. 
If the AVD trunk group has a BCC of 1 or 4, all calls arriving over the AVD trunk 
to the Basic mode complex will be assumed to be multimedia calls. 
ORIGINATION
The basic call sequence from an Enhanced mode complex is to originate a 
multimedia call and alert the destination. When the destination answers the call, 
the originating station’s H.320 desktop video system will be alerted (that is, called 
by the switch to establish the service link). If the H.320 desktop video system is 
not configured for auto-answer, the user must answer the H.320 calls via the DVC 
GUI. If the H.320 DVC is configured for auto-answer, no action is needed via the 
DVC GUI.
 It is recommended, but not required, that Enhanced mode 
complexes place their desktop video system into an auto-answer mode of 
operation.
 If the far-end is providing a video signal, the 2-way video will be 
observed. If the destination is not providing a video signal (call was answered by a 
simple voice station), then loopback video will be provided at the Enhanced mode 
complex originator. The audio signal will exist at the handset of the voice station. 
The audio signal may be moved to the H.320 DVC system via activation of a 
mm-pcaudio button on the voice station. See the section below on mm-pcaudio.
Hourglass tone.  The originating party may hear different things when the 
incoming multimedia call is answered depending on the nature of the answering 
party. If the call is being answered directly by an H.320 DVC system or if the 
answering party is an Enhanced mode complex on a remote switch, an immediate 
audio path will not exist between the two parties. This is because the H.320 
protocol must be established after the call is answered. It takes several seconds for 
the H.320 protocol to establish an audio path. During this interval the originating 
party will hear special ringback. When the audio path exists the special ringback 
will be removed and replaced with a short incoming call tone indicating that audio 
path now exists. The combination of special ringback followed by incoming call 
tone is referred to as “hourglass tone.” Hourglass tone is an indication to the 
originating party that they should wait for the H.320 call to establish audio.
- originating voice calls
Voice calls are originated from the voice station of an Enhanced mode complex in 
the normal manner as for any voice station.
- originating multimedia calls
Multimedia calls from an Enhanced multimedia complex are originated from the 
VOICE STATION, NOT the H.320 desktop video system. All multimedia 
originations require the user to indicate the multimedia nature of the call prior to 
providing any address digits. There are several different ways to originate a 
multimedia call from the voice station.

1.mm-call (Multimedia Call) button. If the station has an mm-call button 
administered, the user goes off-hook and selects the mm-call button. The 
user may select the mm-call button and then go off-hook. If the user has a 
speakerphone on the station, the user may originate the call simply by 
selecting the mm-call button. The speakerphone will automatically be 
placed off-hook and dialtone will be heard. Upon selection of the mm-call 
button, the mm-call status lamp (green led) will light steadily, indicating a 
multimedia call. 
The user now dials the destination address digits. The destination address 
may be provided by dialing digits, using abbreviated dial entries, last 
number dialed, station busy indicators, etc. Originating a multimedia call 
with the mm-call 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. 
For calls with a bandwidth of 2B, use of the mm-call button to originate 
will cause the same destination address to be used for both channels of the 
2B call. See the section below on the mm-multinbr button/FAC for 
information on originating a 2B call where the destination has a different 
address for each B-channel. 
NOTE:
The mm-call feature button is generally used by stations that are part 
of an Enhanced multimedia complex, but may be used by any station 
to originate a multimedia call.
2.
Multimedia Call feature Access Code. For stations that do not have an 
administered mm-call button, the Multimedia call feature access code may 
be used instead. The user goes off-hook on the station, waits for dialtone, 
then dials the MM-call FAC, receives dialtone again and then dials the call 
normally. The destination address may be provided by dialing digits, using 
abbreviated dial entries, last number dialed, station busy indicators, etc. 
Originating a multimedia call with the mm-call 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. 
For calls with a bandwidth of 2B, use of the mm-call button to originate 
will cause the same destination address to be used for both channels of the 
2B call. See the section below on the mm-multinbr button/FAC for 
information on originating a 2B call where the destination has a different 
address for each B-channel.

NOTE:
The mm-call feature access code is generally used by stations that are 
part of an Enhanced multimedia complex, but may be used by any 
station to originate a multimedia call.
3.
mm-multinbr (Multimedia Multi-number) button. The mm-multinbr 
button is similar to the mm-call button. It allows origination of a 
multimedia call from a 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 addresses must be entered. 
The user goes off-hook and selects the mm-multinbr button. The user may 
select the mm-multinbr button and then go off-hook. If the user has a 
speakerphone on the station, the user may originate the call simply by 
selecting the mm-multinbr button. The speakerphone will automatically be 
placed off-hook and dialtone will be heard. Upon selection of the 
mm-multinbr button, the mm-multinbr and mm-call (if present) status lamp 
(green led) should become solid. The user now dials the first destination 
address digits. The destination address may be provided by dialing digits, 
using abbreviated dial entries, last number dialed, etc. The system will 
provide dialtone after the first address has been completed. The user now 
dials the second destination address digits. The destination address may be 
provided by dialing digits, using abbreviated dial entries, last number 
dialed, etc. After the 2nd address has been collected the mm-multinbr 
status lamp will go off.
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. 
NOTE:
The mm-multinbr feature button is generally used by stations that are 
part of an Enhanced multimedia complex, but may be used by any 
station to originate a dual address multimedia call.

4.Multimedia Multi-number Call feature Access Code. For stations that do 
not have an administered mm-multinbr button, the Multimedia 
Multi-number call feature access code may be used instead. It allows 
origination of a multimedia call from a 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 addresses must be entered. 
The user goes off-hook and dials the MM-multinbr feature access code. 
Upon dialing of the MM-multinbr FAC, the mm-call (if present) status 
lamp (green led) should become solid. The user now dials the first 
destination address digits. The destination address may be provided by 
dialing digits, using abbreviated dial entries, last number dialed, etc. The 
system will provide dialtone after the first address has been completed. The 
user now dials the second destination address digits. The destination 
address may be provided by dialing digits, using abbreviated dial entries, 
last number dialed, etc.
Originating a multimedia call with the MM-multinbr FAC 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. 
NOTE:
The mm-multinbr FAC is generally used by stations that are part of 
an Enhanced multimedia complex, but may be used by any station to 
originate a dual address multimedia call.
5.
Multimedia parameter selection feature access code. This FAC is used 
to originate a multimedia call that wishes to use a different bearer and 
bandwidth than the system default. For example, if the system has a default 
multimedia parameter of 2x64 and the user wishes to make a call to a 
destination that is known to only have 56K digital facilities, the MM 
parameter selection FAC can be used to select a bearer and bandwidth of 
2x56 for this specific call. 
The MM parameter selection FAC may be used in conjunction with the 
mm-multinbr button or FAC to make a single or dual address multimedia 
call at the desired bearer and bandwidth. The user goes off-hook and dials 
the MM-parameter selection feature access code. Dialtone is returned. The 
user enters a single digit, 1 or 2, where 1 = 2x64, 2 = 2x56. All other digits 
will produce reorder. Dialtone is returned. Upon dialing of the 
MM-parameter selection FAC, the mm-call (if present) status lamp (green 
led) should become solid. The user may indicate a dual-address call at this

point with the mm-multinbr button or FAC. The user now dials one or two 
sets of destination address digits. The destination address may be provided 
by dialing digits, using abbreviated dial entries, last number dialed, etc. 
NOTE:
The mm-parameter selection FAC is generally used by stations that 
are part of an Enhanced multimedia complex, but may be used by any 
station to originate a dual address multimedia call.

Answering
The user actions required to answer voice or multimedia calls at an Enhanced 
multimedia complex are identical if the H.320 DVC system is configured for 
auto-answer. If the H.320 DVC system is not configured for auto-answer an 
additional step is required. See answering multimedia calls below. 
It is 
recommended, but not required, that Enhanced mode complexes place their 
desktop video system into an auto-answer mode of operation. 
Answering voice calls
Incoming voice calls will alert at the voice station of the Enhanced multimedia 
complex in the normal manner. Standard alerting and call appearance flashing will 
occur. They are answered in the normal manner by selecting the alerting call 
appearance and going off-hook on the voice station.
Answering multimedia calls
Incoming multimedia calls will alert at the voice station of the Enhanced 
multimedia complex in the same manner as voice calls with one addition. If the 
alerting station has an administered mm-call button and the alerting call 
appearance is the selected call appearance (i.e. the red led is lit, on the alerting call 
appearance), then the mm-call button status lamp will go on indicating that the 
call on the selected call appearance is a multimedia call. 
The incoming multimedia call is answered in the normal manner by selecting the 
alerting call appearance and going off-hook on the voice station. If the H.320 
DVC system for the answering party is configured for auto-answer, no other 
action is needed to complete the multimedia call. If the H.320 DVC system for the 
answering party is not configured for auto-answer, the H.320 DVC system will 
alert and must also be answered by the user. 
It is recommended, but not 
required, that Enhanced mode complexes place their desktop video system 
into an auto-answer mode of operation.

If the originating party is providing a video signal, then a complete 2-way 
multimedia call will exist. If the originating party is not providing a video signal, 
the answering party will receive loopback video. The audio signal will exist at the 
handset of the voice station. The audio signal may be moved to the H.320 DVC 
system via activation of a 
mm-pcaudio button on the voice station. 
Hourglass Tone. The answering party may hear different things when the 
incoming multimedia call is answered depending on the nature of the originator. If 
the origination is directly from an H.320 DVC system or if the originator is an 
Enhanced mode complex on a remote switch, an immediate audio path will not 
exist between the two parties. This is because the H.320 protocol must be 
established after the call is answered. It takes several seconds for the H.320 
protocol to establish an audio path. During this interval the answering party will 
hear special ringback. When the audio path exists the special ringback will be 
removed and replaced with a short “incoming call tone” indicating that audio now 
exists. The combination of special ringback followed by incoming call tone is 
referred to as 
“hourglass tone.” Hourglass tone is an indication to the answering 
party that they should wait for the H.320 call to establish audio.
Early Answer. The answering party may administer their station in such a way as 
to avoid hearing hourglass tone. If the station form has set the 
Early Answer field 
to 
y, then 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, the call will then alert at the voice station of the Enhanced mode 
complex destination. 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.
- multiple call appearance operation
With an Enhanced mode complex all calls to or from the complex are controlled 
via the voice station. Each voice or multimedia call has its own call appearance 
which may be selected without regard for the nature of the call using the specific 
call appearance. This allows a multifunction station to control multiple voice or 
multimedia calls in exactly the same way they would control multiple voice calls.
As an example, a user may originate a simple voice call on the first call 
appearance. A multimedia call may then arrive on the second call appearance. The 
user activates HOLD on the first call appearance and selects the second call 
appearance to answer the multimedia call. The user may then activate HOLD on 
the second call appearance and reselect the first call appearance or select a third 
call appearance and originate another call.

- creating a multi-party video conference
An Enhanced multimedia complex can create a spontaneous video conference in 
the same way that a spontaneous voice conference is created. Given an active call, 
the user activates the CONFERENCE button. This puts the current call on HOLD 
and activates a new call appearance. The user makes a multimedia call according 
to the instructions for originating a multimedia call and then selects 
CONFERENCE to combine or merge the two call appearances. This results in a 
3-way conference. 
If all three parties are video equipped, then a 3-way video conference results. 
Conference members see the current speaker on video. The current speaker sees 
the last speaker on video. If one of the parties is not video equipped, then a 3-way 
audio conference exists and the two video equipped parties have 2-way video. The 
CONFERENCE action may be repeated until 6 parties have been conferenced 
together. The 6 parties may be any mix of voice or video, local or remote parties.
The following steps create a multi-party voice/video conference:
1. Enhanced mode complex station A originates a multimedia call to, or 
receives a multimedia call from, party B. Station A and party B have 2-way 
voice and video.
2. Station A, activates CONFERENCE.
3. Station A originates a multimedia call (i.e. uses the mm-call 
button/FAC/etc.) and dials the party to be added, Enhanced multimedia 
complex C.
4. Party C, answers the call from station A.
5. Station A selects CONFERENCE to complete the 3-way conference. 
Parties A,B and C will be in a 3-way voice/video conference.
NOTE:
If party C is another Enhanced mode complex on the same switch as 
station A
, station A does not need to indicate a multimedia call prior to 
dialing the new party in step 3. While A consults with C, the call will be 
audio only. When A completes the conference in step 5, party C’s video will 
be activated.
A multi-party video conference uses voice activated switching to determine which 
parties are seen. The current speaker is seen by all other parties. The current 
speaker sees the previous speaker.
Additional voice or video parties may be added by repeating these steps.

Data Collaboration
Once you have established a multi-point video conference, multi-point T.120 data 
collaboration may be enabled for that call. This will allow all video parties on the 
current conference to collaborate.
T.120 Data conferencing is made possible through the Expansion Services 
Module (ESM) which is an adjunct to the DEFINITY ECS. Up to six parties may 
participate in a single data conference, and up to 24 parties may use ESM facilities 
for data collaboration at any given time. 
The following steps add data sharing to a video conference:
1. Set up a multimedia conference. 
2. Once a multimedia call is active, any member can initiate data 
collaboration by pressing the mm-datacnf button. Or, to use the feature 
access code to initiate a data conference, press the Transfer button. A 
second line-appearance becomes active and you hear dial tone. Dial the 
multimedia data conference feature access code. Confirmation tone is 
heard and the system automatically reselects the held call appearance of the 
multimedia conference. The DEFINITY ECS will select an MLP data rate 
which is acceptable to all H.320 DVC systems in the current call.
If the system does not have sufficient ESM resources available for all 
parties currently in the call, activation of T.120 data sharing will be denied. 
The mm-datacnf status lamp will flash denial or the mm-datacnf FAC will 
produce reorder.
3. Each H.320 DVC system in the conference call is joined to the data 
conference. On many DVC systems, the provided GUI may prompt the 
user with a dialog box, requesting the user to select a specific conference to 
join. With DEFINITY MMCH, there should only be one conference 
available to select.
4.The user must now use the PC’s GUI to begin application sharing. The 
method for beginning application sharing or file transfer is different for 
each H.320 multimedia application. One of the H.320 DVC systems 
activates data sharing from the H.320 DVC vendor provided GUI. See your 
H.320 DVC system documentation for details.
5. The same H.320 DVC system as in step 4, opens an application, 
whiteboard, etc. to share and the image of the application is displayed on 
all H.320 DVC systems in the conference.
For details on how multiple users may control the shared application, see 
the vendor provided documentation for your specific H.320 DVC system.
