E78 Plus/ISDN Software

The E78 Plus/ISDN is a 3270 terminal emulation and file transfer package for micro-mainframe connectivity. However, its use in remote applications was, until recently, limited because of low- speed connections between locations. Now, used with any of the AT&T PC Platforms,

E78 Plus/ISDN provides full 3270 emulation with switched connections through the

AT&T DEFINITY Communications System using either DCP or ISDN-BRI at speeds of 64 kbps.

Applications

The E78 Plus/ISDN software can be used with DEFINITY G1, G2, G3, System 75, System 85, and 5ESS switch. It is particularly useful for those PC users who wish to download large amounts of data stored on central site mainframes to their desktop environment for processing and/or storage. The high-speed connection permits a PC user to transfer a large file quickly from a remote mainframe. Therefore, it is possible for users to download large quantities of data for desktop processing and analysis on a daily basis.

Physical Description

The E78 Plus/ISDN provides a variety of transfer programs (for example, IRMAlink FT/TSO, FT/CMS, and FT/3270) to quickly and safely transfer text and binary files. These programs offer both menu and command-line operation in all major mainframe environments.

On the host side, an AT&T 3270C Data Module must reside between the cluster controller and switch. The PC must be equipped with either PC/ISDN Platform (BRI) Release 1.0 or later or PC/PBX Platform (DCP) Release 3.01 or later software.

Capabilities

The E78 Plus/ISDN software can be used to perform the following activities:

High-speed (64 kbps) connectivity

Eliminate the need for costly remote controllers

Allow terminals to access applications on hosts that are not networked, thereby reducing the number of terminals required

Transfer a large file quickly from a remote mainframe

Integrate with PC/PBX Connection to provide simultaneous voice and data connectivity.
