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 
247).
—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 248.

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 268).
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.

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.

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
