Chapter 1 - Description and
Features
Congratulations on your purchase of the MultiModemII modem. You have acquired one of the finest
intelligent data/fax modems available today from one of the world’s oldest modem manufacturers: Multi-
Tech Systems, Inc. This user guide will help you install, configure, test and use your modem.
Product Description
This modem supports two-wire and/or four-wire leased lines. The four-wire leased line includes the dial
backup and automatic leased line restoration features. Please note that, because leased-line operation
consists of two client modems connected to each other, the maximum leased line data rate is 33.6K bps.
The MT5600BA-V.92 modem supports both two-wire and four-wire leased lines.
The MT5600BA modem supports a two-wire leased line.
The MT5600BL modem supports a four-wire leased line.
The MultiModemII offers interactive automatic dialing. You can store four command lines or telephone
numbers of up to 30 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. It can also detect
AT&T calling card tones. It is FCC-registered for connection to telephone networks without notification to
the telephone company.
The MultiModemII front panel includes a liquid crystal display and four buttons, which together can be
used to either display the current connection status of the modem or to configure the modem. The
MultiModemII also can be configured through standard AT commands.

capture driver installation” - this may cause a delay in the installation. This is normal. The
installation process has not failed or stalled. Simply wait a few moments until this screen
disappears.
4. After installation, you can launch PhoneTools either from a desktop icon or from the Start |
Programs menu. Typically, it’s not necessary to reboot before using PhoneTools.

Chapter 3 - Using the Front Panel

Multi-Tech Systems, Inc. MT5600BA/BL Series User Guide
Chapter 3 - Using the Front Panel
Like any modem, your Multi-Tech modem operates only under the control of a communication
program, such as the PhoneTools program included with the modem. It also operates under other
general-purpose data communication programs, such as Windows Terminal and HyperTerminal. For
information on how to use the modem with the communication program of your choice, please refer to the
program’s documentation.
Modem Con figuration
Your modem normally is configured through Windows or through the communication program you are
using. The default settings work best for most purposes. See “Step 4: Install PhoneTools” in Chapter 2
for help in setting up your communication program.
You also can configure your modem either through the front panel or by sending AT commands to the
modem. The AT commands can be found in the AT Reference Guide on the CD shipped with this
modem.
Figure 3-1. Front panel
LED Indicators
The MT5600BA-V.92 has six LED indicators on the front panel that indicate status and activity:
Receive Data. The RD indicator flashes when the modem is receiving data.
Transmit Data. The TD indicator flashes when the modem is transmitting data.
Carrier Detect. The CD indicator lights when the modem detects a valid carrier signal from
another modem. It is on when the modem is communicating with the other modem, and off when
the link is broken.
Off-Hook. The OH indicator lights when the modem is off-hook, which occurs when the
modem is dialing, online, or answering a call. The LED flashes when the modem pulse-dials.
Terminal Ready. The TR indicator lights when a communication program is using the
modem. It means the modem is ready for an outgoing or incoming call. It goes off when the
communication program disconnects the serial port. When it goes off, a connected modem will
disconnect.
Test Mode. The TM indicator lights when the modem is in test mode.

view, refer to the menu map on the next page.
Trunks are the major divisions of the menu tree. There are seven trunks: Status, Basic Options, Ad-
vanced Options, Remote Configuration, Diagnostics, Phone Number Memory, and Caller ID. Use the áß
and âbuttons to move between trunks.
Limbs are subdivisions of trunks. Use the àbutton to move from a trunk onto its first limb, and the áß
and âbuttons to move between limbs on the trunk.
Branches are subdivisions of limbs. Use the àbutton to move from a limb onto its first branch, and the
áßand âbuttons to move between branches on the limb.
Twigs are status screens and options that are accessible only from branches. Use the àbutton to move
from a branch to its first status screen or option; then press the áßand âbuttons to move between
options, and press the Enter button to select an option.
