The UDS V.3225 is a high-speed modem ideally suited for
applications requiring high data throughput and failure free operation. The modem adheres
to both the CCITT V.32 standard for data transmissions up to 9600 bps (bits per second)
and to the MNP Levels 2 through 5 specifications for error control and data compression.
The V.3225 has a maximum throughput rate of 19,200 bps with outstanding data integrity.
The V.3225 transmits full duplex,
synchronous or asynchronous data at 9600, 4800, 2400 or 1200 bps and asynchronous data at
300 bps. An intelligent modem, the device automatically adjusts the data rate and
modulation scheme to match the remote V.32, V.22bis or Bell 103 modem with which data is
For reliable performance, the V.3225's
advanced microprocessor design incorporates near- and far-end echo canceling, automatic
adaptive line equalizing and trellis coding techniques. The V.3225 includes auto dial and auto answer features
for convenient, easy use. The auto dialer is compatible with the industry standard Hayes
"AT" command set. Dial back-up from leased line to dial line is included to
allow the unit to operate in the event of a leased line failure.
Integral diagnostics aid the user in
isolating communication faults to the data communications equipment, data terminal
equipment or the phone line. For easy setup and for determining the status of modem
operation, the V.3225 data modem features a 2-line by 16-character liquid crystal display
with three control pushbuttons and six LED indicators.
The V.3225 is both a standalone unit (shown) or a plug-in
card for use in the Universal Data Shelf- enclosure.

Easy-to-use controls and indicators For easy set-up and use, the UDS
V.3225 can be completely programmed using three front panel keys and a liquid crystal
display. Pressing the keys as prompted by the menu programs all modem parameters including
strap options. The display is also used for system status, keeping the user informed on
call status and modem operations.
Push "Yes" to answer affirmatively to questions on the LCD
Push "No" to answer negatively to questions on the LCD.
Push "Talk/Data" to end the programming sequence and to determine whether the
telephone line is to be connected to the telset or to the modem.
- QM (Quality Monitor):
On when the signal quality of the modem has diminished. QM is only indicated when the
probable bit error rate (BER) is greater than 1 X 10-1.
- CS (Clear to Send):
On when the DCE (Data Communications Equipment -the modem) is ready to accept data from
the terminal (DTE).
- RS (Request to Send):
On when the DTE (Data Terminal Equipment - PC or terminal) provides a request to send
- CD (Carrier Detect):
On when the received audio signal is detected.
- RD (Receive Data):
On when the modem is receiving data. The RD indicator is on for a space (off for a mark)
at the receive data output activity.
- TD (Transmit Data):
On when the modem is transmitting data. TD is on for a space (off for a mark) at the
transmit data input, to indicate transmit input data activity.
