Introduction
1-2 Issue 2 November 1996
a personal computer (PC) using industry-standard ‘‘auto-dialer’’ PC
communications packages.
The 8400B Plus Data Module is a data service link between a Data Terminal
Equipment (DTE) device, a two-wire telephone, and a Lucent Technologies
DEFINITY
®
Communications System G3V2 or later.
NOTE:
Unless a specific DTE device is intended, the words terminal device shall
be used throughout this guide to represent any applicable DTE device,
including a dumb terminal, or a PC with an appropriate communications
package.
Features
A terminal device is connected to the 8400B Plus Data Module using a standard
Electronics Industries Association EIA-232-D Connector cord and, if needed,
the supplied M9/F25 Adapter. The M9/F25 Adapter converts a 25-pin interface
to a 9-pin interface, adhering to the Electronics Industries Association/
Telecommunications Industry Association EIA/TIA-574 standard. A Digital
Communications Protocol (DCP) interface (using a type D8W modular
telephone cord) is used to connect the 8400B Plus Data Module to the digital
PBX.
The 8400B Plus Data Module may be optioned for use either with or without a
telephone. In the stand-alone case, the 8400B Plus Data Module supports data
service only. Otherwise, the 8400B Plus Data Module provides simultaneous
data and voice service. The 8400B Plus Data Module works with all DCP voice
terminals that support two-wire operation (such as the 8400 series voice
terminals) to provide simultaneous data and voice service.
The voice dial feature allows you to dial a voice call without touching the
telephone. Depending on your communications package, you may also store
telephone numbers on a PC and recall them for dialing, log phone calls for easy
billing, and take notes for later reference during a telephone conversation.
