NOTES:
1. This topic only summarizes information about private networks.
Detailed information is included in the
Network Reference.
2. DEFINITY ECS and DEFINITY ProLogix Solutions features and
operations are beyond the scope of this guide. This book discusses the
network from the MERLIN LEGEND Communications Systems’
perspective.
3. When a network consists of more than two systems, a coordinating
system manager should act as a coordinator for all changes to network
systems dial plans, non-local dial plans, ARS routing, UDP routing, and
remote access. Otherwise, the two system managers should plan
together and agree upon any changes that are made subsequently.
In Release 6.0 and later systems (Hybrid/PBX mode only), MERLIN LEGEND
Communications Systems can be networked with one another or with DEFINITY
ECS or DEFINITY ProLogix Solutions communications systems in private
networks. In previous releases, this functionality is available using tie lines, but
Release 6.0 provides enhanced functionality. Tandem switching permits a system
to route an outside call over a facility that carries the call outside the local system,
rather than routing it to an extension connected to the system. Delay-start (T1-
emulated voice and/or data, or analog) tie trunks or PRI facilities can act as
tandem trunks
to connect networked systems.

* Release 6.0 and later systems only: when the switch type is set to LEGEND-Ntwk or LEGEND-PBX, these
settings are made automatically and cannot be changed unless the switch type is changed. You can add or
remove B-channels from the assigned B-channel group.
