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 
and DEFINITY ECS Maintenance for R7r discuss these commands and their 
output in detail.

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.

Configuring DEFINITY ECS for 
telecommuting
Telecommuting emphasizes the ability to perform telephony activities while 
remote from the DEFINITY ECS. It is a combination of four features which 
permit you to remotely perform changes to your station’s Coverage and Call 
Forwarding.
NOTE:
If you are operating in a DCS environment, you need to assign a different 
telecommuting-access extension to each switch and tell your users which 
extension they should use. A user can set up call coverage from any of the 
DCS nodes, but needs to dial the telecommuting-access extension of the 
node on which their station is defined before using the feature access code.
nCoverage of Calls Redirected Off Net (CCRON) allows you to redirect 
calls off-net onto the public network and bring back unanswered calls for 
further coverage.
NOTE:
If a call covers or forwards off net and an answering machine answers 
the call or it is directed to a cellular phone and a cellular 
announcement is heard, the switch views this call as an answered call. 
The switch does not bring the call back to the switch for further 
routing.

nThe Extended User Administration of Redirected Calls feature allows you 
to change the direction of calls to your station. This activates the capability 
to have 2 coverage path options. These 2 path options can be specified on 
the station screen; however, unless the Can Change Coverage field is set to 
y on the Class of Restriction screen the second path option cannot be 
populated.
nThe Personal Station Access feature gives you an extension number, a 
Merge feature access code, and a personalized security code and tells you 
which office phone you can use. This allows you to take your phone, as 
long as the phones are the same type, anywhere on the same switch. 
nThe Answer Supervision feature provides supervision of a call directed out 
of the switch either by coverage or forwarding and determines whether the 
switch should bring the call control back.
Before you start
Ensure you have the following equipment:
nTone Clock — Tone Detector and Call Classifier 
nCall Classifier — Detector
n1264-TMx software
nDEFINITY extender — switch module or standalone rack mount (Digital 
Communications Protocol (DCP) or Integrated Services Digital Network 
(ISDN))
For more information about this equipment, refer to the DEFINITY ECS 
System Description.
Verify the following fields on the System Parameters Customer-Options
 screen 
are set to y.
nCvg Of Calls Redirected Off-Net
nExtended Cvg/Fwd Admin
nPersonal Station Access
nTerminal Translation Initialization (TTI)
If neither DEFINITY extender nor the System Parameters Customer Options 
fields are configured, contact your Lucent representative.
Verify the telecommuting access extension is a direct inward dialing (DID) or a 
central office (CO) trunk destination for off-premises features to work.
