Adjunct Connections
In addition to station connections, DEFINITY ECS includes many connections for
adjunct (subordinate, related) equipment. The system provides an advanced
X.25 (called BX.25) dedicated link adjunct interface, which can support a variety
of adjuncts, including:
■DEFINITY AUDIX Voice Processing System (internal)
■INTUITY AUDIX Voice Processing System
■Call Management System
The BX.25 interface is also used between DEFINITY ECS systems for Distributed
Communications Service.
DEFINITY ECS also uses an analog Mode Code interface for communications
with INTUITY AUDIX and adjuncts produced by other venders. This interface
employs DTMF tones, line signals, and feature access codes , and allows
adjuncts to exchange data with the DEFINITY ECS without using a data li nk.
DEFINITY ECS provides Electronic Industries Association (EIA) RS-232 port s for
management terminal connections to the active processor and, in the case of
duplication, for management terminal connections to the standby processor. In
addition, a tip/ring connector with a built-in modem is provided for remote admin-
istration.
The Expansion Port Network maintenance circuit pack has a s ingle EIA RS-232
port for connecting a management terminal. Data between the processo r com-
plex and the Expansion Port Network maintenance circuit-pack port is mul ti-
plexed onto the fiber optic link connecting the Expansion Port Network to the
Processor Port Network. The terminal on the Expansion Port Network mai nte-
nance circuit pack has the full capabilities of any other management terminal, but
operates at a lower speed.
Other RS-232 ports connect to the following typical a djuncts:
■Property Management System
■Call Detail Recording Units
■G3 Management Applications
■Call Detail Recording printer
■Basic Call Management System terminals
■System printer
DEFINITY ECS supports CallVisor Adjunct/Switch Applications Interface mes-
sages over ISDN-BRI lines or over the DEFINITY LAN Gateway. CallVisor
Adjunct/Switch Applications Interface allows adjunct computers access to
DEFINITY ECS features and information for computer/telephone integration appli-
cations. CallVisor Adjunct/Switch Applications Interface and DEFINITY EC S sup-
port the following typical adjuncts and applications:
