MultiModemDSVD User Guide 1 Introduction

Introduction

Congratulations on your purchase of your MultiModemDSVD! You have acquired

not only one of the finest intelligent data, fax, and voice modems available, but a

modem that can transmit voice and data at the same time. This user guide will

help you to install, configure, test, and use your modem.

Product Description

The MultiModemDSVD modem incorporates both the ITU-T V.90 and the K56flex™

protocols, both of which enable Internet connections at data rates up to 53K bps*

over standard telephone lines. Using these protocols, Internet service providers

(ISPs) are able to send data downstream to your computer at high speeds because

data on the telephone network normally is converted from digital to analog only once

before it reaches your modem. Upstream transmissions, and transmissions between

client modems, are limited to data rates of 33.6K bps, as are downstream transmis-

sions that are converted more than once on the telephone network.

The MultiModemDSVD offers interactive automatic dialing and command mode

configuration. You can store up to four command line/telephone numbers of up to

40 characters each in the modem’s nonvolatile memory. The modem pulse or tone

dials, and recognizes dial tones and busy signals for reliable call-progress detection.

The modem can also detect AT&T calling card tones. It is FCC-Registered for con-

nection to telephone networks without notification to the telephone company.

Digital simultaneous voice and data (DSVD) operation allows data transfer and

voice conversation to occur simultaneously during a data connection. On a DSVD

call, a headset or microphone and speaker can be used as the voice interface. Both

local and remote modems must have compatible DSVD technology to support the

DSVD function. The MultiModemDSVD is compatible with the industry-standard

ITU-T V.70 DSVD specification.

Features

General

•Complies with major ITU-T, TIA, and EIA international standards to ensure com-

patibility with other modems.

•Distinguishes data, fax, or voice calls using DTMF and tone detection with soft-

ware packages supporting these features.

•Supports serial port speeds to 230.4K bps with compatible serial ports

•On U.S. products, includes Caller ID to identify your caller’s phone number.

*Though this modem is capable of 56K bps download performance, line impairments, public

telephone infrastructure, and other external technological factors currently prevent maxi-

mum 56K bps connections.

MultiModemDSVD User Guide 1 Introduction

Data

•Supports the ITU-T V.90 and K56flexTM standards for data transmission speeds up

to 56K bps while maintaining compatibility with lower-speed modems.

Note: Under the 56K bps standards, you can asymmetrically download data from an

ISP at speeds up to 53K bps, whereas you can upload only at speeds up to 33.6K bps.

•Supports the enhanced ITU-T V.34 standard, with data transmission speeds to

33.6K bps, while maintaining compatibility with lower-speed modems.

•Supports V.90 and K56flex speeds plus 33.6K, 31.2K, 28.8K, 26.4K, 24K, 21.6K,

19.2K, 16.8K, 14.4K, 12K, 9.6K, 7.2K, 4.8K, 2.4K, 1.2K, and 0–300 bps.

•Supports automatic fallback to slower speeds in noisy line conditions, and fall-

forward to faster speeds as conditions improve.

•Supports ITU-T V.42 LAP-M and MNP Class 3 and 4 error correction.

•Supports ITU-T V.42bis (4-to-1) and MNP 5 (2-to-1) data compression.

•Automatically disables compression when transferring already-compressed files.

•Can autodial, redial, pulse (rotary) and touch-tone dial.

•Detects dial tones and busy signals for reliable call-progress detection.

•Compatible with the standard AT command set used by most communication

programs.

•Has MNP10 data throughput enhancement.

•Supports the H.324 protocol (videophone ready).

•Supports distinctive rings to route voice, data, or fax calls on a single phone line.

•Supports Plug and Play (PnP).

•Can be upgraded by flash programming.

Fax

•Supports V.17, Class 1, Class 2, and Group 3 fax communication standards, allow-

ing it to communicate with other fax modems as well as with fax machines.

•Sends and receives faxes from your computer at 14,400 bps, 9600 bps, 7200 bps,

4800 bps, 2400 bps, or 300 bps.

Voice

•Full-duplex speakerphone support with adjustable speaker volume control. Can

record and play back answering machine messages using included microphone

and speaker.

•Remote/local telephone answering machine (TAM) capabilities include voice

mail control, record and playback, and call screening.

•Supports AT#V voice commands.

•Supports DSVD digital simultaneous voice and data.
