AT&T System 85 manual Data Terminals, Technical Specifications

GENERAL INFORMATION

Data Terminals

A data terminal is a workstation at which data is entered and retrieved; it communicates through lines, trunks, switches, and data modules with data endpoints such as computers and other data terminals. Some data terminals contain built-in voice capabilities similar to digital voice terminals. For detailed information on buttons, lights, and tones, refer to the general information about voice terminals at beginning of this section.

The following data terminals are available with System 75, System 85, and DEFINITY G1 and G2:

AT&T Personal Terminal 510A (no longer manufactured)(DA)

AT&T Personal Terminal 510D (no longer manufactured)(DA)

Model 513 Business Communications Terminal (BCT) (no longer manufactured)(DA)

Model 515 BCT (no longer manufactured)(DA)

Model 610 BCT

Model 615 MT

The 513 BCT, 610 BCT, and 615 MT, in addition to being optional units of peripheral equipment, are used in DEFINITY G1 and System 75 as System Access Terminals (SATs). The SAT is dedicated to system administration and maintenance and is located in or nearby the equipment room with the DEFINITY G1 or System 75. This manual does not cover the 513, 610, or 615 as an SAT but only as peripheral data terminals used for sending and receiving data calls.
