TeleTone T-311 Telephone Access Unit
Get the power of personal computer-telephone integration! The Teltone
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
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.
The Teltone T-311 makes your business or organization telephone
contacting more efficient and productive by giving you the power of
personal computer-telephone integration!
- Translates the computerís 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.
- Headset port for hands-free operation.
- Uses the industry standard AT command set for maximum
compatibility with existing communications software.
- Quick, easy installation and setup.
When used in conjunction with contact management software, the T-311
is a powerful automatic dialer. Working with the records from the
software database, it speeds call completion by detecting busy/reorder
tone and immediately moving to the next number. The result is increased
"talk time", thereby improving the efficiency of calling agents.
After a telephone connection has been established, ASCII characters
from the computer are converted to DTMF tones and forwarded to the
network. In the opposite direction, DTMF digits entered at a telephone
keypad are converted to ASCII characters and forwarded to the computer.
Telephone Line Control Features
The T-311 enables computer control of the telephone line, including
the following key features:
The T-311 takes the line off-hook ("seizes" the line) when commanded
by the computer to make or answer a call. The T-311 uses the
standard ATD command to dial outgoing calls, but unlike most modems
it provides full call progress monitoring.
The T-311 places the line on-hook (disconnects) upon command from the
computer, or automatically if a caller fails the security check, loop
current is lost, or inactivity timeout occurs.
The T-311 detects ringing on its incoming line. If response
messages are enabled, the T-311 sends a RING message to the computer.
The call is automatically answered if auto-answer is enabled.
The T-311 puts calls on hold and removes the hold when
commanded by the computer.
Outgoing Call Features
The T-311 controls outgoing calls with the following features:
The T-311 can autodial a series of programmed
numbers. It can also permanently store a number string for repeated
dialing with the command "ATDS".
- Tone and Pulse Dialing
To ensure the widest possible range of
applications, the T-311 works with both DTMF and rotary signaling.
The T-311 can detect both primary and secondary dial tones. In the
autodialing mode, the T-311 can be programmed to delay dialing until
it detects secondary dial tone.
- Call Progress
By detecting and analyzing standard call progress
tones (e.g., reorder, busy, and audible ringing ("ringback"), the
T-311 is able to return information to the computer about the status
of originated calls. By detecting Special Information Tones (S.I.T.),
the T-311 recognizes incomplete calls to speed placement of the next
Incoming Call Features
The T-311 controls incoming calls with the following features:
- Auto and Forced Answer
Auto answer allows unsupervised operation
of the T-311; forced answer commands the T-311 to answer the call.
By disabling answer altogether, the T-311 owner can ensure that the
telephone line is used for making outgoing calls only.
- Security Checking on Answer
When security is enabled, the T-311
automatically disconnects callers who fail to enter the correct
password in the allotted time.
