ffffffffffffffffffffffffffffffffffffff

Asynchronous full-duplex operation at data rates from 1200 bits per second (bps) to 57.6
kilobits per second (Kbps) through an EIA-232-D 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 AT&T’s DMI Mode 2 or
Mode 3 rate adaption protocols.

A user friendly command interface with on-screen help, nine programmable named data
memory numbers, and four programmable data option profiles.

A standard AT command set interface for compatibility with applications which require this
command format.

Remote and local loopback tests.

With ADM II and Feature Package 3, your ISDN set also features the Application Programming
Interface (API).  This interface allows PC communications software to be used to enhance the
operability of your ISDN set.  For example, the API allows a PC communications package
complete control of your ISDN set, from dialing a voice call to answering a voice call.

Some of the many things that an application program running in a PC can accomplish through the
Application Programming Interface include:

A "call screening" feature that examines the calling party number and uses a distinctive ring
based on who is calling.  This allows prioritization of your incoming calls.

An automated personal phone book that looks up the number and places a call to the
specified person.  The application also puts any notes about the person being called on the
computer screen so that it provides the information you need when you need it.

An automated data lookup that identifies an incoming call and searches for any data
available on the caller.  The information is available on a timely basis so that you are
knowledgeable about the incoming call when you answer the telephone.

An automatic redial feature that will retry a busy telephone number and signal you when the
call goes through so that you do not have to waste time constantly redialing.

An automatic conference feature will set up a conference between several parties without the
inconvenience of looking up several numbers and placing several calls.

A variable call forwarding feature prompts the user for a name, retrieves the number from a
data base, and activates call forwarding to that number.

Any of these things, and more, could be happening simultaneously with a data call.
