MERLIN LEGEND Communications System Release 7.0
Feature Reference 555-670-110
Features
Primary Rate Interface (PRI) and T1
eliminates the need to have separate incoming and outgoing lines/trunks when
these services are chosen.
In Release 4.2 and later systems, when PRI is selected as the type of service, any
combination of the following MCI and local exchange carrier services are
supported, in addition to the AT&T services supported in prior releases:
MCI services include:
The system supports the following local DMS-100 local exchange carrier
services:
T1 is the factory setting and, when selected for the DS1 facility, allows each of the
24 channels to be programmed to emulate tie (emulated voice or Switched 56),
loop-start, ground-start, or DID lines or to provide Switched 56 data-only service in
any combination. A single 100D module, therefore, can take the place of 24
regular outside lines/trunks.
In Release 6.0 and later systems (Hybrid/PBX mode only), T1-emulated voice tie
channels and T1-emulated data tie channels can be used to connect MERLIN
LEGEND Communications Systems with one another and/or with DEFINITY ECS
and DEFINITY ProLogix Solutions communications systems in private networks.
