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)
I
NTUITY
 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 I
NTUITY
 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 link.
DEFINITY ECS provides Electronic Industries Association (EIA) RS-232 ports 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 single EIA RS-232 
port for connecting a management terminal. Data between the processor com-
plex and the Expansion Port Network maintenance circuit-pack port is multi-
plexed onto the fiber optic link connecting the Expansion Port Network to the 
Processor Port Network. The terminal on the Expansion Port Network mainte-
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 adjuncts:
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 ECS sup-
port the following typical adjuncts and applications:
