NOTE:
When you move ESM circuit packs, you MUST remove the DS1 and 
signaling group translations. You cannot use the 
change circuit pack 
command.
When a vector is used to route video (56K/64K) calls to a hunt group comprised 
of data extensions, the vector 
must have the multimedia field set to n. This field 
causes 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 and starts 
network billing for the incoming call when vector processing begins.
Understanding the multimedia 
complex
1-number access. 1-number access permits originating users to make voice or 
multimedia calls to a Basic 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 directs it to 
the telephone. If the incoming call is 56K or 64K data call, DEFINITY ECS 
recognizes it as such and sends it to the multimedia endpoint. Likewise, if a voice 
call is addressed to the data extension, the system recognizes this and directs the 
call to the voice station. 
Calls originating on the same switch as the Basic 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 data 
non-PRI digital facilities multimedia calls must be made to the data extension.
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. 
Originating voice calls. All voice calls are originated at the voice station.
Originating multimedia calls. For a Basic mode complex, multimedia calls are 
normally originated at the user’s multimedia equipped PC. These multimedia calls 
use the associated station’s COR/COS.

The voice station of a Basic multimedia complex may also use the “mm-call” 
button or FAC, and the “mm-multinbr” button or FAC to originate multimedia 
calls. When these methods are used, a multimedia call is originated from the voice 
station. In order for the Basic multimedia complex to receive video, the user must 
make a call from the H.320 DVC system to the voice station of the complex or 
must make a multimedia call from the voice station to the H.320 DVC. This 
allows the station to spontaneously add themselves or other parties to a 
multimedia conference. 
1.
H.320 DVC system GUI. The normal way for a Basic multimedia complex 
endpoint to originate a multimedia call is through the vendor provided user 
interface. Generally, digits to dial are entered, speed is selected and the call 
originates from the DVC system. The voice station is not involved in such 
as origination.
Any voice station may use the following mechanisms to originate a 
multimedia call from the voice station. For stations that are not part of a 
multimedia complex, video cannot be provided. For voice stations that are 
part of a Basic multimedia complex, video is not provided until a 
multimedia call is made from the complex’s H.320 DVC system to the 
voice station or a multimedia call is made from the voice station to the 
H.320 DVC system. Video is automatically included for Enhanced 
multimedia complexes.
2.
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) should become solid. 
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.
3.
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.
4.
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 light steadily. 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.
5.
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.

6.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.

Receiving voice calls. Any voice calls directed to the voice or data extension of 
a Basic multimedia complex will ring at the voice station.
Receiving multimedia calls. Any data calls directed to the voice or data 
extension of a Basic multimedia complex will ring at the multimedia equipped PC 
if it is available. You may answer the multimedia call at the PC and voice and 
video will connect to the PC. If the data endpoint is unavailable, the system 
verifies that the telephone of the complex is administered with the H.320 field set 
to y. If so, the system converts the call to voice and sends it to the telephone of the 
multimedia complex, where the call then alerts.

Hourglass Tone. When a voice station answers a converted multimedia call, the 
answering party may hear different things 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 to avoid hearing 
hourglass tone. With the station form 
Early Answer field set to y, the system 
answers the incoming multimedia call on behalf of the station and establishes the 
H.320 protocol. After audio path has been established, the call will then alert at 
the voice station of the Basic 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.
If the H.320 field is not set to y for the telephone of a Basic multimedia complex, 
H.320 calls alert at the multimedia endpoint until the caller drops. If an H.320 call 
is directed to a telephone with H.320 set to n, the system denies the call.
You can assign H.320 conversion to any voice station. 
Authorization. Multimedia complexes require the same types of authorization 
(COR/COS) as standard telephones. If a call is addressed to the voice extension, 
the system checks the COR/COS of the telephone, whether the call is voice-only 
or multimedia. If a call is addressed to the data extension, the system checks the 
COR/COS of the data endpoint. If the call is subsequently redirected to the voice 
station, the system does a second COR/COS check for the authorization of the 
voice station. Calls originated from the PC use the COR/COS of the voice station. 
Adjunct Switch Applications Interface . ASAI is not expected to support 
call-association for data calls. Therefore Lucent Technologies does not 
recommend that you use ASAI for multimedia. 
Administered Connections. Basic Multimedia endpoints may serve as the 
origination point or destination of an administered connection. 
Authorization and Barrier Codes. Basic Mode multimedia users or off-premises 
PC users may not be able to respond to prompts for authorization or barrier codes. 
Multimedia endpoints do not recognize the prompts.

An on-premises user might be able to use Remote Access and enter the entire digit 
string at once before launching the call, but it would be better to eliminate the 
need for such codes for multimedia users who need to call off premises. 
Bridged Appearances. Voice users can bridge onto a call if the user has a 
bridged appearance of a voice member of the call. 
Call redirection. Calls directed to either member of the Basic multimedia 
complex are subject to redirection (coverage, forwarding). DEFINITY ECS 
converts calls to voice before sending them to coverage. Calls redirected through 
call forwarding maintain multimedia status if forwarded from the data endpoint. 
Conferencing . A multimedia conference can consist of multimedia and 
voice-only conferees. All multimedia conferees are added to a multimedia 
conference by a voice-terminal user on the switch, who acts as the controller of 
the multimedia conference. When the controller is a Basic complex voice station, 
the controller must remain on the conference until all parties have joined. Once all 
endpoints are on the conference, the voice-terminal user may put the call on hold 
or drop, if the user wishes. 
Video conferees can see only their local video and one other party. If more than 
two people are involved in a video conference, the person who is speaking is the 
one whose video appears to other conferees. The speaker’s video shows the 
previous speaker. This changes dynamically as the speaker changes. 
Creating a multi-party video conference
All multimedia conferences must be controlled by a voice phone. Multimedia 
conferees may be added by calling the voice phone or by having the voice phone 
make a multimedia call to other DVC endpoints. The controller can then 
conference together individual parties to create a multimedia conference. 
To set up a multimedia conference:
 
1. Determine who is going to be the conference controller. 
2. At the appointed time, the conference controller calls his or her telephone 
from the multimedia endpoint by dialing the 1-number extension. Once this 
call is established, the controller conferences in other calls as if this were a 
voice conference. The controller continues to add conferees in this manner 
until all conferees have joined, or until the number of conferees reaches the 
administered limit. 
3. The conference controller may also add voice or multimedia parties to the 
conference spontaneously. The controller hits CONFERENCE, makes a 
voice or multimedia call to a new party. To make a multimedia call, the 
controller must originate a call using the mm-call button or FAC or the
