Prior Releases: Features and Enhancements
Release 6.0 Enhancements (February 1998)
Service Cost Savings. In addition to toll call savings, there are two ways
that organizations can save on service costs incurred from
telecommunications providers that provide public switched telephone
network access:
Voice Mail and Auto Attendant. Networked systems (prior to Release
6.1) should have their own local voice mail and/or auto attendant
applications as well as their own external alerts and Music-On-Hold
sources. A single Auto Attendant, however, 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.
might dial, 916175551211. The local ARS tables would route this
call over the private networked trunks and use the ARS tables of the
remote system in Boston to route this call. 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.
— 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 64 kbps per channel or 128 kbps for 2B data, while keeping the
remaining B-channels available 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.
