Call Handling - AT&T MERLIN LEGEND Reference

Overview

Call Handling

Placing and receiving calls on a BRI line is the same as placing and receiving
calls on loop-start or ground-start lines. Making BRI digital data calls is the
same as making Primary Rate Interface (PRI) digital data calls.
Incoming Calls
An incoming call to a BRI line can terminate on Personal Line buttons, Direct
Pool Termination (DPT) buttons, Calling Groups, and the Queued Call Console
(QCC) queue.
Outgoing Calls
When a user lifts the receiver and presses a BRI line button on a telephone, the
MERLIN LEGEND system sets up a call to the 5ESS central office (CO). The
button's light-emitting diode (LED) turns to green to show that the line is active.
The CO provides dial tone. As the user dials digits, they are sent to the CO.
Like other lines, a BRI line can be accessed via a DPT button or via a System
Access button through pool access codes.
Like other lines, a BRI line can be accessed via Automatic Route Selection
(ARS). ARS routes calls over outside lines according to the number dialed and
the lines available. As with PRI facilities, a user can take advantage of ARS
routing for the type of call (voice or data). For example, if data is frequently sent
to a particular number in another area of the country, ARS can route calls to that
number over high-speed data lines.
H o l d
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-BRl lines.
