MultiModemDID User Guide
Chapter 1 - Introduction and Description
Welcome to the world of data communications. You have acquired one of the finest intelligent data and
fax modems available today from one of America’s oldest and most respected modem manufacturers:
Multi-Tech Systems, Inc. This User Guide will help you install, configure, test, and use your modem.
Introduction
The MultiModemDID combines Direct Inward Dial (DID) with Super G3 V.34/33.6K bps fax and V.92 data
modes of operation. Direct Inward Dial allows the user to use a block of telephone numbers larger than
the number of physical telephone lines for direct dialing to extensions. When combining DID with inbound
fax calls to a fax server, each user on the fax server can have faxes automatically routed to them at their
client computer desktop.
DID fax routing assigns a unique fax number for every network user or network device (such as a
printer). Senders simply dial a typical telephone number - no special procedures are required. The fax
server automatically delivers the incoming fax to the user over the local area network.
Users get improved efficiency and security, since their faxes are delivered by the network fax server to
the client desktop as soon as they are received. Time-wasting trips to the fax machine are eliminated and
employees are more productive. In addition, DID offers a higher degree of security for both the sender
and the recipient since faxes are not left unattended at a central fax machine.
The MT5634ZBA-DID utilizes Super G3 V.34 fax speeds of 33.6K bps. Now, computer-based fax servers
can achieve the Super G3 speeds found in dedicated fax machines. The MT5634ZBA-DID also supports
T.31 Annex B and T.32 Annex C, which allows the higher V.34 speeds to operate with Class 1.0 and
Class 2.1 code sets. In addition, “on-the-fly” two-dimensional fax data compression plus support for error
correction mode (ECM) increase the performance of the MT5634ZBA-DID to levels previously only found
in expensive fax boards and dedicated fax machines.
To implement DID fax routing you must purchase fax server application software that supports Multi-Tech
DID commands and DID routing, and obtain an analog DID trunk line which supports the inbound fax
calls and a regular loop-start line for outbound fax transmission.

MultiModemDID User Guide
Chapter 2 - Installation
Step 1: Assemble the Modem
The only assembly required is to mount the feet on the bottom of the modem. Simply peel the four self-
adhesive plastic feet off the backing strip and press them into the recesses on the bottom of the modem.
Step 2: Connect the Modem to Your System
Turn off your computer. Place the modem in a convenient location, and then connect it to your
computer’s serial port, the phone line, AC power, DID line, and your phone.
Connect the Modem to Your PC
Plug one end of the serial cable into the connector on the modem, and plug the other end into a
serial port on your computer, such as COM1 or COM2.
Connect the Modem to the Telephone Line
Plug one end of the phone cable into the modem’s LINE jack and the other end into a phone wall
jack. The phone cable is included with your modem.
Note: The LINE jack is not interchangeable with the PHONE jack. Do not plug the phone into the LINE
jack or the line cable into the PHONE jack.

MultiModemDID User Guide
(Optional) Connect the Modem to the Phone
For voice-only calls, plug a phone into the modem’s PHONE jack.
Connect the Modem to the AC Power Outlet
Make sure the power is switch is OFF. Plug the DC power transformer into a power outlet or power
strip. Plug the other end into the PWR jack on the modem. The DC power transformer is included
with your modem.
CAUTION: Use only the DC power transformer supplied with the modem. Use of any other
transformer voids the warranty and can damage the modem.
Connect the Modem to the DID Line
Plug one end of the phone cable into the modem’s DID jack and the other end into an analog DID
trunk line jack. The DID Line cable is included with your modem.
CAUTION: The DID Line cable has a 4-pos RJ11 on one side and a 6-pos on the other. Never plug
the DID connector into a standard POTS Line. This may damage the modem or the central office
equipment. Use only an analog DID Line.
Power-on Test
Test the modem by turning it on (an on-off switch is located on the side panel). When you apply
power, the modem performs a diagnostic self-test. The 56 indicator lights, and if a terminal program
is running, the TR indicator also lights. If this does not happen, check that the power switch is on,
the power supply is solidly connected, and the AC outlet is live. If these measures do not work, see
the Troubleshooting chapter.
Step 3: Install the Modem Driver
1. Make sure your modem is connected properly, and then turn on your computer. Windows should
detect your new modem and open the Install New Modem wizard.
Note: If Windows cannot find a modem, your modem may be turned off, it may be plugged into the
wrong connector on your computer, or the serial cable may be faulty. See “None of the LEDs Light
When the Modem Is Turned On” and “The Modem Does Not Respond to Commands” in the
“Troubleshooting” chapter in the complete User Guide.
2. Insert the MT5634ZBA-DID CD into your CD-ROM drive, and then click OK.
3. Windows installs the modem driver.
4. Click Finish to exit
Removing Your Old Modem from Windows
When your new modem replaces another modem, the old modem installation remains in Windows after
you install the new modem, and the old modem is still selected in HyperTerminal and other Windows
applications. Although you can change the application connection descriptions one at a time, it is easier
to force Windows applications to use the new modem by removing the old modem from Windows.
