Data Communications with This System

Data Communications Overview

Resource Sharing
Data communications is the transmission of words or symbols from a source to a
destination by means of electrical signals. This chapter gives you an overview of
the features and equipment used for data communications with this system.
The communications system offers many advanced data features designed to
reduce costs, improve efficiency, and automate your data communications
process. These features can be used to share resources, share data (with
advanced data connectivity features), and provide advanced network services
that integrate voice and data (telemanagement).
Resource sharing lets users share data terminal equipment (DTE) including
personal computers, printers, ports, or computer systems and data
communications equipment (DCE), including modems or data modules, to
reduce costs.
The advantages include simplified and less expensive wiring and reduced
cabling costs; better use of expensive hardware, including printers, plotters,
and high speed modems; and fewer host computer port requirements.
The communications system supports these data features through
data hunt groups (DHGs)
external modem pooling
analog data support
digital data support
clear channel 64-kbps digital transmission
ISDN 7500B Data Module
