Asynchronous full-duplex operation at data rates from 1200 bits per second (bps) to 57.6

kilobits per second (kbps) through an EIA-232 interface.

d

Circuit switched data communication over 56 or 64 kbps facilities via industry standard

V.120 rate adaption protocol.

d

Circuit switched data communication over 64 kbps facilities via AT&T’s Digital Multiplexed

Interface (DMI) Mode 2 or Mode 3 rate adaption protocols.

d

API allows a PC to control all aspects of the set’s interaction with the user and with the

network.

d

The four softkeys and four display control buttons located below the liquid crystal display

can be used to access data features such as view current options, change options,

answer a data call, place a data call, reset a locked data set, and selecting to display a

data indicator.

d

A user friendly command interface with on-screen help, nine programmable named data

memory numbers, and four programmable data option profiles.

d

An expanded Hayes AT command set interface for compatibility with applications which

require this command format.

d

Remote and local loopback tests.

For more information about the data features on an 8500-Series terminal, see the 

ISDN 8500

Series Display Terminal ADM User’s Manual, 555-021-730.

For DEFINITY G2, and G3, in which multipoint configuration is used, the maximum signaling dis-

tance possible from the port board to the work location jack is: (The terminating resistor should

be within 250 feet of the work location; the distances listed  are applicable for up to two voice/data

terminals.)
