Connections to ECS

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 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:
