MERLIN LEGEND Communications System Release 6.1
Pocket Reference 555-661-116
Release 6.0 Enhancements (February, 1998)
The system managers at each end of a private network set
up ARS and Remote Access features to implement this
functionality.
In addition, local organizations or incoming DID calls use
—
private networked trunks to make intersystem calls
between networked systems, which may be
geographically distant from one another, also resulting in
toll savings.
Service Cost Savings. In addition to toll call saving, there
—
are two ways that organizations can save on service costs
incurred from telecommunications providers that provide
public switched telephone network access:
You order a point to point T1 facility from a service
—
provider, then use system programming to set it up for PRI
signalling. As necessary, a service provider can provide
amplification on the T1 facility, but does not supply
switching services.
You can tailor your use of PRI B-channels with drop-and-
—
insert equipment that allows fractional use of B-channels
for dedicated data/video communications between
systems at speeds greater than 64kbps per channel or
128 kbps for 2B data, while keeping the remaining
B-channels for PRI voice traffic. The PRI D-channel
must remain active.
You can tailor use of T1 channels to support both T1-
—
emulated tandem tie service and T1 Switched 56 service
for data communications at 56 kbps per channel, allowing
2B data transfers at 112 kbps. You can also use drop-and-
insert equipment to provide fractional T1 use.
Voice Mail and Auto Attendant. Networked systems should
—
have their own local voice mail and/or auto attendant
applications as well as their own external alerts and Music
On Hold sources. However, a single auto attendant can
transfer calls throughout the network. It can answer only
those calls that arrive on the PSTN facilities of the system
where it is connected.
Although many features are available using tie trunks for
network connectivity, PRI tandem trunks provide greatly
enhanced features and faster call setup. For this reason, PRI is
recommended over tie functionality in private networks.
Group Calling Enhancements
Release 6.0 and later systems include Group Calling features
that enhance group calling operations.
Queue Control
—
The system manager can control the maximum number of
calls allowed in the primary calling group queue for calls that
arrive on certain facilities often assigned to calling groups.
When the number of the calls in queue reaches the
programmed maximum, subsequent callers receive a busy
signal.
Queue control applies to calls received on the following types
of facilities:
DID (Direct Inward Dialing)
—
PRI facilities programmed for dial-plan routing
