Get the power
of personal computer-telephone integration! Teltone's T-311 Telephone Access
Unit enables computers to control telephone system functions such as answering
and placing calls, observing call status, sending or receiving DTMF signals,
"flashing" the line, and coupling audio sources onto the line.
The T-311 is a highly flexible tool
for applications where DTMF access and control of computers and other equipment
is needed. It lends itself to specialized application development, involving
simple code writing.
The T-311 automates virtually all
your calling, giving you the speed of a predictive dialer, without the expense
and complexity. Applications for the T-311 include university alumni
fund-raising, remote testing, voice messaging, and remote monitoring or control
of alarm systems, energy management systems, and more.
Teltone's T-311 makes your business
or organization telephone contacting more efficient and productive by giving you
the power of personal computer-telephone integration!
The T-311 offers the following
capabilities:
-
Translates the computer's
language (ASCII code) into the language of the telephone network (DTMF tones),
and vice versa.
-
Detects and analyzes call
progress tones such as dial tone, reorder, busy, and ringback, and informs
computer of outgoing call status with ASCII code.
-
Detects presence of voice when
outgoing call has been answered.
-
Answers incoming calls, and can
be enabled to answer after a specified number of rings.
-
Protects your system with
programmable password security.
-
Interfaces to and provides
control of audio sources such as tape players or speech synthesizers for
recording or playing back messages as directed by the computer.
-
Connects to headset for
hands-free operation.
-
Uses the industry standard AT
command set for maximum compatibility with existing communications software.
-
Quick, easy installation and
setup.
With the T-311 Telephone Access
Unit computers can make and answer telephone calls, and information about those
calls can be returned to the computer. While a modem only transmits data from
computer to computer over telephone lines, the T-311 allows communication
between called and calling parties.
The T-311 is used for a variety of
applications where automating the process of making and receiving calls is
desired. These applications include commercial, industrial, and business
environments as well as non-profits and university environments.
Applications for the T-311 fall
into three basic categories: outgoing calls, incoming calls, and security for
incoming calls.
Outgoing Calls:
This is the most sophisticated application for the T-311,
particularly when incorporation of the proper applications software and an audio
source allow the T-311 to operate without human supervision.
Incoming Calls:
In this type of application, the caller uses the T-311 to
update or verify information in a remote computer database.
Inward Security:
The T-311's security checking feature can be used for
incoming call applications like dialback security systems or building security
systems.
