Conference
Calls on BRI lines can be part of a conference call, but the conference is
processed by the MERLIN LEGEND system, not by the 5ESS central office
(CO). The MERLIN LEGEND system determines the number of active parties on
the call.
Like a standard MERLIN LEGEND system, the MERLIN LEGEND BRI system
supports up to five people on a conference: two within the system, two outside
the system, and the call originator.
NOTE:
If a MERLIN LEGEND user is part of a conference established by an outside
party via the CO Conference feature, the MERLIN LEGEND system may play
MOH (if so programmed) when the MERLIN LEGEND user puts the call on hold.
Transfer
A user can transfer calls two ways on a MERLIN LEGEND BRI system. One way
is to transfer calls by using the standard MERLIN LEGEND Transfer feature. The
MERLIN LEGEND Transfer feature works the same with BRI lines as with other
lines. With this Transfer feature a user can transfer the following calls:
Intercom call to a MERLIN LEGEND station
CO call to a MERLIN LEGEND station
Intercom call to a station outside the system
CO call to a station outside the system
This last transfer, called Trunk-to-Trunk Transfer, ties up both CO facilities
involved in the transfer.
The second way of transferring calls to outside destinations is to use the CO
Transfer feature. With CO Transfer, the user can connect two outside parties
without tying up the BRI lines that were used to establish the connection. In
essence, when CO Transfer is used, the transfer bounces back to the 5ESS CO,
letting the CO handle it and thereby freeing the BRI lines to handle more calls.
For more information, see the "BRI Features" section later in this chapter.
