Chapter 1 - Introduction
Congratulations on your purchase of the MultiModem® II intelligent data/fax modem, model MT5600BR-V92.
You have acquired one of the finest internal data/fax modems available today from one of the world’s
oldest modem manufacturers: Multi-Tech Systems, Inc. This User Guide will help you to install, configure,
test, and use your modem.
Product Description
The MT5600BR-V92 incorporates ITU-T V.92 protocol which provides quick connections, downstream
transmissions at speeds up to 56K bps*, and upstream transmissions at speeds up to 48K bps when
connected to V.92-compatible Internet service providers. Transmissions between the MT5600BR-V92 and
other client modems are limited to 33.6K bps, as are upstream transmissions to non-V.92-compatible
ISPs and downstream transmissions that are converted more than once on the telephone network.
Fax Communications: Supports Class 1, 1.0, and Class 2 faxing at 14.4K bps.
Features: Modem features include automatic fallback to slower speeds in noisy line conditions, and fall
forward to faster speeds as conditions improve. 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.
NOTE:
*Though this modem is capable of 56K bps download performance, line impairments, public telephone
infrastructure, and other external technological factors currently prevent maximum 56K bps connections.
General features
•Supports V.92/56K download speeds and 48K upload speeds when connecting with V.92 server
•Automatic fallback to slower speeds in noisy line conditions, and fall forward to faster speeds as
conditions improve.
•Serial port data rates adjustable to 115.2K bps
•ITU V.42 LAP-M and MNP Class 3 and 4 error correction
•ITU V.42bis (4-to-1), ITU V.44bis (6-to-1), and MNP 5 (2-to-1) data compression
•Automatic disabling of compression when transferring already compressed files
•Autodial, redial, pulse (rotary), and touch-tone dial
•Dial tone and busy signal detection for reliable call-progress detection
•Distinctive ring support to route data or fax calls on a single phone line
•FlashROM upgradable (customer upgradable in a Windows environment)
•Compatibility with the standard AT command set used by most communication programs
•Nonvolatile memory for storage of customized modem parameters and ten telephone numbers
Fax
•Responds to Class 1, 1.0, and Class 2 fax commands, enabling it to exchange editable and
encrypted faxes with other Windows computers
•Sends and receives faxes from your computer at 14,400 bps, 9600 bps, 7200 bps, 4800 bps, 2400
bps, or 300 bps

LED Indicators
The MT5600BR-V92 has ten LED diagnostic indicators.
RCV XMT CO 56 33.6 14.4 OH DTR RI ERR
RCV - This LED blinks when data is being received, on for a space, off for a mark. The state of this
RCV LED matches that of the RCV circuit on Pin 3 of the RS232C/V.24 interface.
XMT - This LED blinks when data is being transmitted, on for a space, off for a mark. The state of
this LED matches that of the XMT circuit on Pin 2 of the RS232C/V.24 interface.
CO - This LED lights when a valid carrier tone has been detected.
56 - This LED is lit when the modem connects using V.92 protocol. The actual connection speed
depends on ISP server capabilities and line conditions.
33.6 - This LED is lit when the modem is connected at 33,600 bps. Note that when both 33 and 14
LEDs light, modem is in 16,800 to 33,600bps mode of operation.
14.4 - This LED is lit when the modem is connected at 14,400 bps.
OH
- This LED is lit when the phone line is “off hook” . This occurs when the modem is dialing, on
line, or answering a call. The LED also flashes when the modem is pulse dialing in the
Command Mode.
DTR - When the DTR LED is lit, the modem is permitted to answer an incoming call. When DTR
goes off, a connected modem disconnects if dependent on DTR. The state of this DTR LED
matches that of the DTR circuit on Pin 20 of the RS232C/V.24 interface.
RI - This LED is lit during the ringing interval as an incoming call is received.
ERR - When the ERR LED is flashing, the leased line is down and the modem is in self-test mode
has failed. When ERR LED is on, this indicates the modem is in an out of service ( OOS ) state.
When the modem is out of service, it is busy to incoming calls.

SafetyWarnings
•Use this product only with UL- and CUL-listed computers (U.S.A.)
•To reduce the risk of fire, use only UL-listed 26 AWG (.41mm) or larger telephone wiring.
•Never install telephone wiring during a lightning storm.
•Never install a telephone jack in a wet location unless the jack is specifically designed for wet
locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
•Avoid using a telephone during an electrical storm; there is a risk of electrical shock from lightning.
•Do not use a telephone in the vicinity of a gas leak.
•The telephone cord is to be disconnected before accessing the inside of the equipment.
Card Cage
The MT5600BR-V92 is designed to mount in the Multi-Tech Systems' modem rack. This rack is an EIA-
standard 19-inch wide by 7-inch high rack, and mounts in any standard computer cabinet. The rack has a
sixteen modem slot capacity, redundant power supply capability, sixteen 25-pin (female) connectors for
RS232C/V.24 interface and sixteen RJ11 back-plane connectors for phone line interface.
Serial Cable
You must provide a serial cable to connect each corresponding MT5600BR-V92 to your computer. The
cable must have a DB-25 male interface into the modem rack.
Telephone Line
The MT5600BR-V92 uses one RJ11 jack per corresponding modem slot to connect to the telephone line.
One end of the RJ11 cable provided with the modem connects the rack's RJ11 connector (located on the
back plane of the modem rack) and the other end connects to the phone-company-provided RJ11 or
RJ11W modular phone jack.

PC Board Controls
The MT5600BR-V92 is designed on a single printed circuit board. This board contains sixteen DIP-
Switches. There is a two-position "Out of Service" (OOS) toggle switch that extends from the front of the
modem circuit card. There is also a two-position TEST/OOS berg jumper located towards the back and
center of the card.

The sixteen DIP-Switches and berg jumper control various modem options or set default values for the
MT5600BR-V92 Command mode. There is a difference in how several of the switches operate depending
on whether you are in synchronous or asynchronous mode (DIP-Switch #12).
Most communications software packages have installation procedures of their own, which call for certain
modem DIP-Switch settings. If you are using such a package, follow the software's instructions.
DIP-Switch Settings
The vast majority of installations are similar, with the MT5600BR-V92 being used to dial up a remote
installation where the call is automatically answered. The factory default DIP-Switch settings are based
on this assumption. The following is a brief description and summary of the MT5600BR-V92's DIP-Switch
options:
Switch Function Position Effect
#1 DTR Forced/ UP* DTR dependent on interface
DTR from Interface * DOWN DTR forced ON at all times
#2 Flow Control &E4* UP* Hardware flow control
(Async/Dial-Up/Leased Line) DOWN Software flow control

#3 Result Codes Enabled* UP Q1 Disable Responses
