tandem switching
A number assigned to a tandem trunk in a private network .
It identifies the system connected to the far end of the
trunk. Switch identifiers are based on the type of system
and its distance from the system where the identifier is
assigned. See also satellite system and non-satellite
system .
Method of transmitting a continuous digital data stream in
which the transmission of each binary bit is synchronized
with a master clock. See also asynchronous data
transmission .
Test of all trunks, telephones, data terminals, and features
after installation to ensure that they are working correctly.
See SA buttons .
Date and time that appear on MLX display telephones and
SMDR reports.
Programming of system functions and features that affect
most users, performed from an MLX-20L telephone or a
computer using SPM . See also extension programming
and centralized telephone programming.
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 Switched 56 service .
The capability of private network communications systems
that allows them to direct outside calls from one facility to
another facility, rather than just to an extension. Calls may
be sent, for example, from a PSTN facility to a tandem
trunk or vice versa.
