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 programmed 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
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 telephone 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 might dial,
. The local ARS tables would route this
call over the private network trunks and use the ARS
tables of the remote system in Boston to route this call.
