Data Features
■ 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.
■ X.25 packet switched data communication including receipt of X.29
commands from a remote X.25 host for setting packet switched data
parameters.
■ Circuit switched data communication over 56 or 64 kbps facilities via
industry standard V.120 rate adaption protocol.
■ Circuit switched data communication over 64 kbps facilities via Lucent
Technologies’ Digital Multiplexed Interface (DMI) Mode 2 or Mode 3 rate
adaption protocols.
■ API allows a PC to control all aspects of the set’s interaction with the user
and with the network.
■ 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.
■ A user friendly command interface with on-screen help, nine programmable
named data memory numbers, and four programmable data option profiles.
■ An expanded Hayes AT command set interface for compatibility with
applications which require this command format.
■ Remote and local loopback tests.

Distance Limitations
For the DEFINITY G2 and G3 and DEFINITY ECS, in which multipoint
configuration is used, the maximum signaling distance possible from the port
board to the work location
jack is:
NOTE:
The terminating resistor should be within 250 feet of the work location; the
distances listed are applicable for up to two voice/data terminals.
■ If 24 AWG cable is used = 1600 feet
■ If 26 AWG cable is used = 1330 feet
