Trunk supervisory signaling, used between two
communications systems, in which signaling information is
transferred through two-state voltage conditions (on the Ear
and Mouth leads) for analog applications and through two
bits for digital applications. See also tie trunk .
(Electronic Industries Association)
Physical interface, specified by the EIA , that transmits and
receives asynchronous data at speeds of up to 19.2-kbps
over cable distances of 50 feet (15 m).
See ESS .
Final destination in the path of an electrical or
telecommunications signal.
An application that sends calls to available agents in a
calling group. The Enhanced Service Center places calls in
queue, plays announcements, tracks agent activity and
availability, and provides real-time reports.
(extended superframe format) PRI framing format
consisting of individual frames of 24 eight-bit slots and one
signal bit (193 bits) in a 24-frame extended superframe.
(Electronic Switching System) Class of central office ( CO )
switching systems developed by Lucent Technologies in
which the control functions are performed principally by
electronic data processors operating under the direction of
a stored program.
Carrier added to the control unit when the basic carrier
cannot house all of the required modules. Houses a power
supply module and up to six additional modules.
Data communications device that allows connection
between an RS-232 DTE device and the control unit using
MLX extension jacks on the 008 MLX or 408 GS/LS-MLX
module.
See ESF .
An endpoint on the internal side of the communications
system. An extension can be a telephone with or without an
adjunct. Also called "station." See also data workstation.
An analog, digital, or tip/ring physical interface on a module
in the control unit for connecting a telephone or other
device to the system. Also called "station jack."
