Programming of system functions and features that affect
most users, performed from an MLX-20L telephone or a
computer using SPM . See also
and Centralized Telephone
See SPM .
Procedure used to change the numbers assigned to
telephones, adjuncts , calling group s, paging groups, park
zones, Remote Access , and lines/trunks.
Type of digital transmission facility that, in North America,
transmits at the DS1 rate of 1.544 mbps.
A T1 tie trunk programmed for S56DATA for use by data
calls at speeds up to 56 kbps. These trunks may be used
for tandem and non-tandem operation.
A T1 tie trunk programmed for Tie-PBX or Tie-Toll for use
by voice calls.
T1 digital data transmission over the public network or over
a private network at 56 kbps. See
Capability of private network communications systems that
allows them to direct outside calls from one facility to
another, rather than just to an extension. Calls may be
sent, for example, from a PSTN facility to a tandem trunk ,
or vice versa.
Private outside facility (as opposed to an inside system
line) that connects two communications systems in a
private network and can carry calls to another outside
facility through tandem switching . The trunk is not
connected to the PSTN .
Tandem trunk that is an analog delay-start tie trunk ,
providing a single line/trunk per facility and allowing analog
transmission of voice and low-speed data; or a T1 facility
offering 24 channels on emulated tie trunks and
programmed for voice or data.
Tandem Primary Rate Interface Trunk . Private network
trunk .
Telephony Application Programming Interface . Application
programming interface that allows computer telephony
applications to be used. TAPI is not yet supported by the
MERLIN LEGEND Communications System. See also
