Release 4.0 Enhancements (March 1996)
Users can override the Coverage VMS Off button status at any
time by pressing the programmed Coverage VMS Off button to
turn the LED on or off.
■ Night Service Group Line Assignment
Beginning with Release 4.1, a system manager can assign lines
to Night Service groups to control handling of after-hours calls
received on individual lines. This capability replaces the
automatic assignment to Night Service groups of only those
lines that ring on the Night Service operator console. An outside
line must be assigned to a Night Service group to receive Night
Service treatment.
With this enhancement, Night Service can be activated and
deactivated on lines that do not appear on operator consoles
(for example, personal lines), and lines appearing at operator
positions can be excluded from Night Service.
■ Forward on Busy
Beginning with Release 4.1, the Forward, Follow Me, and
Remote Call Forward features are enhanced to remove the
requirement that a call be ringing at an extension before it can
be forwarded. With the Forward on Busy enhancement, a call to
an extension with no available SA or ICOM buttons is forwarded
immediately to the programmed destination, preventing the
caller from hearing a busy signal from the intended call
recipient’s extension.
■ Maintenance Testing for BRI Facilities that Are
Part of Multiline Hunt Groups (MLHGs)
Beginning with Release 4.1, the NI-1 BRI (National Integrated
Services Digital Network-1 Basic Rate Interface) Provisioning
Test Tool is enhanced to include testing for BRI facilities that are
part of Multiline Hunt Groups (MLHGs).
The NI-1 BRI Provisioning Test Tool is used by Lucent
Technologies maintenance personnel on MERLIN LEGEND
Communications Systems that include an
800 NI-BRI module. Technicians use the tool during system
installation and maintenance to test the functionality of the BRI
lines and to report analyzed results.
Release 4.0 Enhancements (March 1996)
Release 4.0 includes all Release 3.1 functionality, plus the
enhancements listed below.
■ Support for Up to 200 Extensions
An expanded dial plan supports up to 200 tip/ring devices.
■ Support for National ISDN BRI Service
This service (Hybrid/PBX and Key modes) provides an
alternative to loop-start and ground-start lines/trunks for voice
and digital data connectivity to the central office. Each of the
two B-channels (
bearer channels
) on a BRI line can carry one
voice and one data call at any given time. The data speeds on a
B-channel are up to 28.8 kbps for analog data and up to 64
kbps for digital data, which is necessary for videoconferencing
and other high-speed applications. Release 4.0 supports the
