Multimedia Call Handling

■ Service Link Mode — The service link is the combined hardware and
software multimedia connection between an Enhanced mode complex’s
H.320 DVC system and the Avaya DEFINITY Server which terminates the
H.320 protocol. A service link is never used by a Basic mode complex
H.320 DVC system. Connecting a service link will take several seconds.
When the service link is connected, it uses MMI, VC and system timeslot
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 Avaya DEFINITY
Server 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.
■ Multimedia 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
307).
