Release 6.0 includes all Release 5.0 functionality, plus the enhancements listed
below.

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 up to 20 patterns, associated
routes, Facility Restriction Levels (FRLs), digit absorption, and digit
prepending. This allows ARS-like routing of non-local dial plan calls. In
addition, system managers can control whether calling name, calling
number, or both are shown at MLX display telephones for incoming calls
across PRI tandem trunks.
Toll Savings. Private networked trunks may allow you to realize significant
cost savings on long-distance and toll calls by performing tandem switching
in the following two ways:
— Callers on a local system, or individuals dialing in to remote access
at a local system, can reach the public switched telephone network
(PSTN) via outside trunks connected to other systems in a private
network, avoiding toll charges or decreasing the cost of toll calls. No
special dialing is required. For example, an organization might have
a main office in Boston and a subsidiary office in New Jersey
connected by networked private tandem trunks between two
systems. A user in the New Jersey office who wishes to make an
outside call to the 617 area code (Boston) can do so through a line/
trunk connected to the system in Boston. For example, he or she
