Description
The Motorola / UDS V.3225 / V3225 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 Motorola / UDS V.3225 / V3225 has a maximum throughput rate of 19,200
bps with outstanding data integrity.
The Motorola / UDS V.3225 / V3225 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 being exchanged.
For reliable performance, the Motorola /
UDS V.3225 / V3225's
advanced microprocessor design incorporates near- and far-end echo canceling,
automatic adaptive line equalizing and trellis coding
techniques. The Motorola / UDS V.3225 / V3225 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 Motorola / UDS V.3225 / V3225 data modem features a 2-line by
16-character liquid crystal display with three control pushbuttons and six LED
indicators.
The Motorola / UDS V.3225 / V3225 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 Motorola / UDS V.3225 / V3225 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.
Controls:
Yes:
Push "Yes" to answer affirmatively to questions on the LCD
No:
Push "No" to answer negatively to questions on the LCD.
Talk/Data:
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.
Indicators
- 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 signal
- 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.
