MERLIN LEGEND Communications System Release 5.0
Feature Reference 555-650-110
Features
Basic Rate Interface (BRI)
Hyphens are inserted between the digits on incoming calls, for example,
555-1234 for a 7-digit display and 123-555-1234 for a 10-digit display. Any other
number of digits appears without hyphens.
A brief description of the display support provided in Release 4.0 and later
systems follows. Refer to
NOTE:
BRI display support for Release 4.0 and later systems applies to MLX
display telephones only. There is no BRI-specific display support for analog
multiline telephones.
Incoming BRI Calls (Non-Group Calling). When the calling party
information is available from the network, the Calling Party Number (CPN)
appears on the user's display. Pressing the More button shows the Called
Party Number on the second screen of the display. If the Called Party
Number is more than 15 characters in length, the digits at the end are
dropped.
Group Calling. The MLX display of a calling group member shows the
original Called Party Number. Pressing the More button shows the Calling
Party Number on the second screen of the display.
Transfer without Consultation. In Release 4.0 and later systems,
pressing the More button on an MLX display telephone that is a transfer
destination shows the original Called Party Number.
Outgoing Calls
Outgoing calls on BRI lines can be made using one of three methods:
Personal Line. When an idle personal line that represents a BRI line is
accessed, the communications system sets up a call to establish a
connection to the central office. The status light turns green and dial tone is
provided by the central office. As digits are dialed, they are transmitted to
and processed by the central office.
Pool Button. Like any other type of line/trunk, a BRI line can be accessed
via a Pool button or by using an SA button and dialing a pool access code.
Automatic Route Selection. Like any other type of line/trunk, a BRI line
can be accessed by using an SA button and dialing the Automatic Route
Selection (ARS) access code. ARS processing may modify the dialed
number through standard digit deletion and addition processing. ARS can
also take advantage of the distinction between voice and data calls for
routing purposes when making outbound calls over BRI lines. 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.
