Call Waiting is provided on BRI lines at extensions so programmed. The
call-waiting tone is not blocked from BRI at an extension if turned on.
Calls on BRI lines can be part of a conference call processed by the
MERLIN LEGEND system, not by the central office (CO). The MERLIN
LEGEND system determines the number of active parties on the call.
The MERLIN LEGEND Communications System supports up to five
people on a conference: two within the system, two outside the system,
and the call originator.
If a MERLIN LEGEND user is part of a conference established by an
outside party through the central office Conference feature, the MERLIN
LEGEND system may play Music On Hold (if so programmed) when the
MERLIN LEGEND user puts the call on hold.
An active call on a BRI line can be placed on hold by using the MERLIN
LEGEND Hold feature. All call appearances (such as LEDs) are the
same as for other non-BRI lines.
Recall is not recognized by the central office (CO) on BRI lines.
Therefore, pressing the recall button on a telephone is ignored by the
CO.
The number of a BRI line is shown in the LINE field of the SMDR report.
Call timing begins when the call is answered. Therefore, calls that are
not answered do not have an SMDR call record generated.
See Appendix F for print reports showing the actual SMDR fields.
Calls on BRI lines are available for the MERLIN LEGEND
Communications System Transfer feature. The central office based
Transfer feature is not supported by the MERLIN LEGEND
Communications System.
Higher quality video calls require more than 1 B-channel. For more
information on video conferencing see the Data and Video Reference .
