Release 6.0 Enhancements
—
If the number of waiting calls is greater than the
Threshold 2 value but less than the Threshold 3 value,
the LED flashes.
—
If the number of waiting calls is greater than the highest
value, Threshold 3, the LED lights steadily.
NOTE:
A DSS (Direction Station Selector) button that is used as a
Calls-in-Queue Alarm button can only indicate two
threshold levels, either by flashing or by lighting steadily. If
a calling group must use this type of Calls-in-Queue Alarm
button, only two threshold levels should be programmed.
If all three thresholds are set to the same value, the result is
one threshold only. If two values are the same, then the
result is two alarm levels. The factory setting is one call for all
three thresholds.
An external alert only signals when the number of calls in the
queue exceeds the programmed Threshold 3 value.
—
MLX-5 and MLX-5D Telephones. The MLX-5 nondisplay
and the MLX-5D display telephones are compatible with all
system releases. The display telephone includes a 2-line by
24-character display, and both telephones come with 5 line
buttons.

Private Networks
In Hybrid/PBX mode systems only, MERLIN LEGEND
Communications Systems can be networked with one another
or with DEFINITY
®
Enterprise Communications Server (ECS)
and ProLogix
™
Communications Systems in private networks.
In previous releases, this functionality is available using tie
lines, but users handle calls between networked switches as
outside calls. In this release, dialing the pool access code is not
necessary for a call going from one networked switch to
another. Also, delay-start tie trunks or T1 trunks administered as
PRI can act as
tandem trunks to connect networked systems.
Available for Hybrid/PBX mode systems, the private network
features of the MERLIN LEGEND Communications System
Release 6.0 provide the following advantages for
geographically dispersed organizational sites:
—
Intersystem Calling. In a private network, users on one
local system can call extensions on other systems in the
network. Release 6.0 can support 2-, 3-, 4-, or 5-digit dial
plans. They dial these extensions as inside calls. To
implement this function, the system manager programs the
extension ranges of remote networked switches to create a
non-local dial plan. This programming does not actually
affect numbering on the remote system. To correctly set up
systems for transparent calling among non-local dial plan
extensions, the system manager assigns networking tie and/
or PRI tandem trunks to pools. Then he or she programs as
many as 20 patterns, associates with routes, Facility
