About the Leased-Line Operation Feature  
The MultiModemIND can be used on a two-wire leased line.  
A leased line is a private, permanent telephone connection between two points. Unlike normal dialup connections, a  
leased line is always active. The modems automatically connect when they are attached to the line and are turned  
on. Because a leased line is always active, one of the two modems on the line must be configured as the originate  
modem and the other as the answer modem; however, it does not matter which is which.  
In the event of an interruption, leased-line modems automatically reconnect when the data line or power is restored.  
Setup  
1. Connect a modular telephone cable to the LINE jack. Connect the other end of the cable to a two-wire  
lease-line jack or terminals supplied by the telephone company.  
2. Turn on the modem.

Mounting  
The MT5634IND is design to be used on the desktop or to be panel-mounted. For panel-mounting, follow these  
directions for attaching the mounting brackets:  
1. Typically, the modem is mounted against a flat surface with two mounting screws. Drill the mounting holes at  
the desired location. The mounting holes must separated by 4 -7/16 inches center-to-center.  
2. To attach the brackets to the modem, slide the mounting brackets into the corresponding slots on the back  
of the chassis.  
3. Attach the modem to the surface with two screws.

Chapter 2 – Installation  
Step 3 – Install the Modem Driver  
If you use Windows 98+, you must install the modem driver, which is installed using the Windows Plug and Play  
feature. Follow the four-step procedure below. If you use another operating system, see your operating system  
manual.  
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.  
2. Insert the MT5634IND product CD, and then click OK.  
3. Windows installs and configures the modem.  
4. Click Finish to exit.  
Windows NT – The Install New Modem wizard presents one additional prompt before Step 2. At this prompt,  
select: Don’t detect my modem; I will select it from a list, and then click Next.

MT5634IND (the driver is named Multi-Tech MT5634SMI-V92-IND).  
Note: If Windows cannot identify your modem (for instance, if it identifies your modem as a “Standard Modem”),  
click Change. Return to the MT5634IND CD and open the drivers section. Select the Multi-Tech MT5634SMI-  
V92-IND driver.  
Step 4 – Configure the Modem for Your  
Country or Region  
Different countries have different requirements for how modems must function. Therefore, before you use your  
modem, you must configure it to match the defaults of the country/region in which you are using it. You must also do  
this if you move the modem to another country/region after it has been configured for the first country/region. You can  
use one of two country/region configuration methods:  
The Global Wizard  
AT Commands  
Using the Global Wizard  
The Global Wizard configuration utility isrecommended for computers running Windows 95 or newer.  
1. Insert the MultiModemIND product CD into the CD-ROM drive. The Autorun menu should appear.  
2. Click Initial Setup and Country/Region Selection.  
3. Choose either:  
Run Global Wizard from CD. This will not load the wizard onto your hard drive, or  
Install Global Wizard on the HD. This will install the wizard onto your PC for future use.  
4. The Global Wizard dialog box appeared. Click Next.  
5. The Global Wizard searches for your modem and identifies it. Click Next.  
6. Select the country/region in which the modem will be used. Click Next.  
7. Review your country/region choice. If it is correct, click Next to configure the modem.  
8. When Global Wizard announces that the parameters have been set, click Finish to exit.  
Using AT Commands  
Non-Windows users can configure the modem using AT commands. You must enter these commands in your  
communication program’s terminal window. To configure the country/region code, the initialization string must  
contain the AT command for your specific country or region.  
1. Run a communications program, such as PhoneTools (included on the MT5634IND CD) or  
HyperTerminal.  
2. Type AT%T19,0,nn, where nn is the country/region code in hexadecimal notation.  
Click Enter. The message OK displays.  
3. To verify that the correct country/region has been configured, type:  
ATI9 and click Enter.  
4. The country/region code displays:  
Example:  
Country/Region  
AT Command (hexadecimal)  
Result code (decimal)

Step 5 – Install Data Communications  
Software  
Data communications software is designed to send and receive messages. Multi-Tech includes PhoneTools, a  
communications software program with your modem. However, the modem will work with other data communications  
software, such as HyperTerminal.  
To install PhoneTools, insert the CD into the CD-ROM drive; click the PhoneTools icon. You will be asked to choose  
your language. The software automatically loads onto your PC.  
PhoneTools  
PhoneTools is a data communications program included as part of your MultiModemIND purchase. With this  
software you can:  
Upload and download data files.  
Send faxes at preset times.  
Store incoming voice messages and faxes.  
Retrieve stored messages, faxes, and telephone numbers (telephone number retrieval requires Caller ID  
service from your telephone company).  
Print a received fax.  
For detailed information about operating your modem under PhoneTools, please refer to the PhoneTools user  
documentation included with the PhoneTools software.

Chapter 4 – Remote Configuration  
Chapter 4 – Remote Configuration  
Remote configuration is a network management tool that allows you to configure MT5634IND modems anywhere in your  
network from one location. With password-protected remote configuration, you can issue AT commands to a remote  
modem for maintenance or troubleshooting as if you were on site.  
Basic Procedure  
The following steps can be used when the connection is established by the local or the remote modem.  
Note: The remote computer must be running and a communication program must be ready for a data connection, which  
will be indicated by a lighted TR indicator on the front of the modem.  
1. Establish a data connection with a remote MT5634IND modem.  
2. Send three remote configuration escape characters followed by AT and the setup password, and press Enter.  
Example: %%%ATMTSMODEM.  
You have four tries to enter the correct password before being disconnected. If the password is correct, the  
remote modem responds with OK.  
3. You can now send AT commands to configure the remote modem.  
4. When you have finished configuring the remote modem, save the new configuration by typing AT&W0 and  
pressing Enter.  
5. Type ATO and press Enter to exit remote configuration. You can now break the connection in the normal way.  
Setup  
Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who has the User  
Guide knows the default setup password, you should change the password.  
Changing the Setup Password  
1. Open a data communications program such as HyperTerminal or PhoneTools.  
2. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the  
MTSMODEM password with xxxxxxxx) and press ENTER. The modem responds with OK if the setup  
password is correct, and ERROR if it is wrong.  
3. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and then  
press ENTER. The password can include any keyboard character, and can be up to eight characters long.  
The modem responds with OK.  
CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the same  
case as you set it up.  
4. The new password is saved automatically. You can now either enter more AT commands or exit the data  
communications program. The next time you wish to set up the modem, you must use the new password.  
Changing the Remote Escape Character  
To further improve security, you can change a remote modem’s remote configuration escape character either  
locally or remotely. The remote configuration escape character is stored in register S9. The factory default is 37,  
which is the ASCII code for the percent character (%). Setting S9 to 0 (zero) disables remote configuration  
entirely. CAUTION: If you do this remotely, you won’t be able to change it back remotely.  
1. Establish a remote configuration link with the remote modem as described in Basic Procedure.  
2. Type ATS9=n, where n is the ASCII code for the new remote configuration escape character, and then  
press Enter.  
3. Save the new value by typing AT&W and pressing Enter.  
4. Type ATO and press Enter to exit remote configuration.

Chapter 5 – Callback Security  
Chapter 5 – Callback Security  
This chapter describes how to use callback security with your modem. Callback security protects your network from  
unauthorized access and helps control long-distance costs. When callback security is enabled, all callers are  
requested to enter a password. If a valid password is received, the modem hangs up and returns the call by dialing a  
phone number that is stored with the password. The person being called back must then enter the password a  
second time to establish a connection.  
Up to 30 callback passwords and dialing strings can be stored in the modem. Each dialing string can be up to 34 or  
35 characters long and can contain commands as well as phone numbers. For mobile callers, the dialing string can  
be programmed to allow the caller to bypass the stored callback number by entering a temporary callback number, to  
enter an extension at the callback number, or to make a direct connection without callback.  
For local security, the passwords and dialing strings that are stored in the modem are protected from tampering by a  
setup password, which you should change when you set up the modem. You can further protect the modem against  
tampering by disabling its ability to respond to most AT commands. To check for attempted break-ins, you can  
request the modem to display the number of failed password attempts.  
Your modem was shipped with a default setup password (MTSMODEM). The same password is used for both  
callback security and remote configuration. Because anyone who has access to this guide has access to the default  
password, you should change the password during your initial setup.  
Changing the Setup Password  
1. Open a data communications program such as PhoneTools.  
2. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the MTSMODEM  
password with xxxxxxxx). Press ENTER. The modem responds with OK if the setup password is correct and  
ERROR if it is wrong.  
3. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and then press  
Enter. The password can include any keyboard character, and can be up to eight characters long. The  
modem responds with OK.  
4. The new password is saved automatically. You can now either enter more AT commands or exit the data  
communications program. The next time you wish to set up the modem, you must use the new password.  
CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the same  
case as you set it up.  
Turning Callback Security On and Off  
Callback security must be turned on to enter many callback security commands.  
1. Open a data communications program such as PhoneTools.  
2. In the terminal window, type AT#Sxxxxxxxx, where xxxxxxxx is your password. Press Enter. The modem  
responds with OK if the setup password is correct and ERROR if it is wrong.  
3. Type one of the following commands:  
To turn off callback security: Type AT#CBS0 and press Enter. Callers no longer need a password to  
connect to the modem, the modem is unable to call them back, and the stored dialing command  
locations 0–3 become available.  
To turn on both local and remote callback security: Type AT#CBS1. Press Enter. With local  
security turned on, you must enter the setup password before you can enter any AT command except  
the AT, ATIn, and AT#Sxxxxxxxx commands.  
To turn on remote callback security only: Type AT#CBS2 and press Enter. With remote callback  
security turned on, each caller is asked to enter a password, is called back, and then is asked to enter  
the password again before a connection can be made. Also, dialing command locations 0–3 for use with  
the DS=y dialing command are replaced by callback dialing command locations 0–29.  
To temporarily disable callback security if the modem is set to #CBS1 or #CBS2 (for instance, to  
call another modem): Type AT#CBS3 and press Enter. The modem returns to its original setting  
when you issue the hangup command (+++ATH) or the modem is reset. Note that if a remote modem  
breaks the connection, callback security remains disabled.

Chapter 5 – Callback Security  
Setting Callback Security Message Parity  
The password prompt and messages parity must match the parity of the computer to which the modem is connected.  
1. Open a data communications program such as PhoneTools.  
2. In the terminal window, type AT#Sxxxxxxxx, where xxxxxxxx is your password. Press Enter. The modem  
responds with OK if the setup password is correct and ERROR if it is wrong.  
3. The modem’s parity default value is No parity (AT#CBP0). To change the modem’s default to use even  
parity, type AT#CBP2. Press Enter. For odd parity, type AT#CBP1. Press Enter.  
4. To store the new parity value, type AT&W. Press Enter.

Chapter 6 – Troubleshooting  
Chapter 6 – Troubleshooting  
Your modem was thoroughly tested at the factory before it was shipped. If you are unable to make a successful  
connection, or if you experience data loss or garbled characters during your connection, it is possible that the modem  
is defective. However, it is more likely that the source of your problem lies elsewhere. The following symptoms are  
typical of problems you might encounter:  
None of the LEDs light when the modem is on.  
The modem does not respond to commands.  
The modem cannot connect when dialing.  
The modem disconnects while online.  
The modem cannot connect when answering.  
File transfer is slower than it should be.  
Data is being lost.  
There are garbage characters on the monitor.  
The modem doesn’t work with Caller ID.  
Fax and data software can’t run at the same time.  
If you experience problems, please check the following possibilities before calling Technical Support.  
None of the Indicators Light  
When you turn on the modem, the LED indicators on the front panel should flash briefly as the modem runs a self-  
test. If the LEDs remain off, the modem is probably not receiving power.  
Make sure the modem’s power switch is on, especially if you normally turn the modem on by turning on a  
power strip.  
If the modem is plugged into a power strip, make sure the power strip is plugged in and its power switch is  
on.  
Make sure the power supply is firmly connected to the modem and the power supply’s power cord is firmly  
connected to both to the power supply and the wall outlet or power strip.  
If the power strip is on and the modem switch is on, try moving the power supply to another outlet on the  
power strip.  
Test that the outlet is live by plugging another device, such as a lamp, into it.  
The modem or power supply may be defective. If you have another Multi-Tech modem, try swapping  
modems. If the problem goes away, the first modem or power supply might be defective. Call Technical  
Support for assistance.  
CAUTION: Do not under any circumstances replace the power supply with one designed for another product; doing  
so can damage the modem and void your warranty.  
The Modem Does Not Respond to Commands  
Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”)  
Make sure you are issuing the modem commands from data communication software, either manually in  
terminal mode or automatically by configuring the software. (You cannot send commands to the modem  
from the DOS prompt.)  
Make sure you are in terminal mode in your data communication program, then type AT and press ENTER. If  
you get an OK response from your modem, your connections are good and the problem likely is in the  
connection setup in your communication software.  
Try resetting your modem by turning it off and on. If you are using DOS or Windows 3.1 communication  
software, make sure the initialization string includes &F as the first command, to cancel any “leftover’  
command that could affect the modem’s operation.  
If you don’t get an OK, the problem may still be in the communication software. Make sure you have done  
whatever is necessary in your software to make a port connection. Not all communication programs connect  
to the COM port automatically. Some connect when the software loads and remain connected until the  
program terminates. Others can disconnect without exiting the program. The modem’s TR indicator lights to  
show that the software has taken control of the modem through the COM port.  
Multi-Tech Systems, Inc. MT5634IND User Guide (S000369A)  
19  
 
Chapter 6 – Troubleshooting  
Your communication software settings may not match the physical port to which the modem is connected.  
The serial cable might be plugged into the wrong connector—check your computer documentation to make  
sure. Or you might have selected a COM port in your software other than the one the modem is physically  
connected to—compare the settings in your software to the physical connection.  
If the modem is on, the cable is plugged into the correct port, the communication software is configured  
correctly, and you still don’t get an OK, the fault might be in the serial cable. Make sure it is firmly connected  
at both ends.  
Is this the first time you have used the cable? If so, it may not be wired correctly. Check the cable  
description on the packaging to make sure the cable is the right one for your computer.  
Peripheral expansion cards, such as sound and game cards, might include a serial port preconfigured as  
COM1 or COM2. The extra serial port, or the card itself, may use the same COM port, memory address, or  
interrupt request (IRQ) as your communication port. Be sure to disable any unused ports.  
Windows 9x: Right-click on My Computer, select Properties from the menu, click on the Device Manager  
tab, double-click on Ports, then double-click on the communication port your modem is connected to. In the  
port’s Properties sheet, click on the Resources tab to see the port’s input/output range and interrupt  
request. If another device is using the same address range or IRQ, it appears in the Conflicting Device  
List. Uncheck Use automatic settings to change the port’s settings so they do not conflict with the other  
device, or select the port the conflicting device is on and change it instead. If you need to open your  
computer to change switches or jumpers on the conflicting device, refer to the device’s documentation.  
Windows NT 4.0: To look for address or IRQ conflicts, click Start, Programs, Administrative Tools  
(Common), and Windows NT Diagnostics. In the Windows NT Diagnostics dialog box, click the  
Resources tab to see which input/output ranges and interrupt requests are in use. If you need to open your  
computer to change switches or jumpers on the conflicting device, refer to the device’s documentation.  
The serial port might be defective. If you have another serial port, install the modem on it, change the COM  
port setting in your software, and try again.  
The modem might have a problem beyond the scope of this user guide. If you have another Multi-Tech  
modem, try the other modem. If there is no problem with the other modem, call Technical Support for  
assistance.  
The Modem Cannot Connect When Dialing  
There can be several reasons the modem fails to make a connection. Possibilities include  
lack of a physical connection to the telephone line.  
a wrong dial tone.  
a busy signal.  
a wrong number.  
no modem at the other end.  
a faulty modem, computer, or software at the other end.  
incompatibility between modems  
poor line conditions.  
You can narrow the list of possibilities by using extended result codes. Extended result codes are enabled by default.  
If they have been disabled, include V1X4 in the modem’s initialization string, or in terminal mode enter ATV1X4 and  
press Enter. When you dial again, the modem reports the call’s progress.  
If the modem reports NO DIALTONE, check that the modem’s telephone line cable is connected to both the  
modem’s LINE jack (not the PHONE jack) and the telephone wall jack. If the cable looks secure, try  
replacing it. If that doesn’t work, the problem might be in your building’s telephone installation. To test the  
building installation, plug a telephone into your modem’s telephone wall jack and listen for a dial tone. If you  
hear a dial tone, your modem might be installed behind a corporate phone system (PBX) with an internal dial  
tone that sounds different from the normal dial tone. In that case, the modem might not recognize the dial  
tone and might treat it as an error. Check your PBX manual to see if you can change the internal dial tone. If  
you can’t, change your modem’s initialization string to replace X4 with X3, which will cause the modem to  
ignore dial tones.  
If the modem reports BUSY, the other number might be busy, in which case you should try again later.  
However, it might indicate that you have failed to add a 9, the prefix to the phone number if you must dial 9  
for an outside line.  
If you must dial 9 to get an outside line, the easiest way to dial it automatically is to include it in the modem’s  
dial prefix; e.g., ATDT9. Note the comma, which inserts a pause before the number is dialed. By inserting 9,  
into the dial prefix, you do not have to include it in each directory entry.  
To change the dial prefix in Windows HyperTerminal, select Connect from the Call menu, click Dialing  
Properties, and type 9 in the local and long distance boxes in How I dial from this location.  
Multi-Tech Systems, Inc. MT5634IND User Guide (S000369A)  
20  
 
Chapter 6 – Troubleshooting  
If there is no answer on the remote end, the modem reports NO CARRIER. You might have dialed a wrong  
number, and a person answered instead of a computer, or you might have dialed the correct number but the  
other computer or software was turned off or faulty. Check the number and try again, or try calling another  
system to make sure your modem is working. Also, try calling the number on your telephone. If you hear  
harsh sounds, then another modem is answering the call, and the modems might be having problems  
negotiating because of modem incompatibilities or line noise. Try connecting at a lower speed.  
Poor line conditions can affect the connection. When using V.34 or V.32 client-to-client connections in poor  
conditions, setting S38=0 may result in better performance.  
The Modem Disconnects While Online  
If you are not using Modem on Hold, Call Waiting can interrupt your connection when someone tries to call  
you. If you have Call Waiting service, disable it before each call. In most telephone areas in North America,  
you can disable Call Waiting by preceding the telephone number with *70 (but first check with your local  
telephone company).  
You can automatically disable Call Waiting by including the disabling code in the modem’s dial prefix (e.g.,  
ATDT*70, – note the comma, which inserts a pause before the number is dialed). To change the dial prefix  
in Windows HyperTerminal, select Connect from the Call menu, click Dialing Properties, check This  
location has Call Waiting, and select the correct code for your phone service.  
If you have extension phones on the same line as your modem, you or someone else can interrupt the  
connection by picking up another phone. If this is a frequent problem, disconnect the extension phones  
before using the modem, or install another phone line especially for the modem.  
Check for loose connections between the modem and the computer, the telephone jack, and AC power.  
You might have had a poor connection because of line conditions or the problem might have originated on  
the other end of the line. Try again.  
Your ISP might have hung up on you because of lack of activity on your part or because you exceeded your  
time limit for the day. Try again.  
Modem Cannot Connect When Answering  
The default DTR Control command (&D2) inhibits autoanswer. To enable autoanswer, change DTR Control  
to &D0, and make sure &Q0, &Q5, or &Q6 is also set. For more information, see the &D command in the  
AT Commands Reference Guide. For information on changing the modem’s default configuration, see  
“Install and Configure Your Software” in Chapter 2.  
Autoanswer might be disabled. Turn on autoanswer in your communications program or send the command  
ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.  
File Transfer Is Slower Than It Should Be  
If you are using a slow transfer protocol, such as Xmodem, try Zmodem or Ymodem/G instead.  
Is your line noisy? If there is static on your line, the modem has to resend many blocks of data to insure  
accuracy. You must have a clean line for maximum speed.  
Are you downloading a compressed file with MNP 5 hardware compression enabled? Since hardware data  
compression cannot compress a file already compressed by an archiving program, the transfer can be  
marginally slower with data compression enabled than with it disabled.  
Does your Internet service provider (ISP) use the same 56K protocol as your modem? The default setting of  
your modem is to connect using either the V.92 or the V.90 protocol, depending on which one the ISP’s  
modem is using. If your ISP uses the V.90 protocol, the maximum speed you will be able to upload at is  
33,600 bps. Check with your ISP to see which protocols it supports.  
Are you trying to send a file to another client modem? If so, then your maximum possible connect speed is  
33,600 bps. You can upload at speeds up to 48,000 bps only when connected to an ISP that supports the  
V.92 protocol.  
Try entering the I11 command in online mode or the &V command in command mode to display information  
about the last connection, making a screen print of the connection statistics, and checking for parameters  
that might be unacceptable.  
Multi-Tech Systems, Inc. MT5634IND User Guide (S000369A)  
21  
 
Chapter 6 – Troubleshooting  
Data Is Being Lost  
If you are using data compression and a high speed serial port, set the serial port baud rate to two to six  
times the data rate.  
Make sure the flow control method you selected in software matches the method selected in the modem.  
Try entering the I11 command in online mode or the &V command in command mode to display information  
about the last connection, making a screen print of the connection statistics, and checking for parameters  
that might be unacceptable.  
There Are Garbage Characters on the  
Monitor  
Your computer and the remote computer might be set to different word lengths, stop bits, or parities. If you  
have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your communication software.  
You might be experiencing line noise. Enable error correction, if it is disabled, or hang up and call again; you  
might get a better connection the second time.  
At speeds above 2400 bps, the remote modem might not use the same transmission or error correction  
standards as your modem. Try connecting at a slower speed or disabling error correction. (With no error  
correction, however, line noise can cause garbage characters.)  
Try entering the I11 command in online mode or the &V command in command mode to display information  
about the last connection, making a screen print of the connection statistics, and checking for parameters  
that might be unacceptable.  
The Modem Doesn’t Work with Caller ID  
Caller ID information is transmitted between the first and second rings, so if autoanswer is turned off (S0=0)  
or if the modem is set to answer after only one ring (S0=1), the modem will not receive Caller ID information.  
Check your initialization string, and if necessary change it to set the modem to answer after the second ring  
(S0=2).  
Make sure that you have Caller ID service from your telephone company.  
Fax and Data Software Can’t Run at the Same  
Time  
Communication devices can be accessed by only one application at a time. In Windows 95 and higher, you  
can have data and fax communication applications open at the same time, but they cannot use the same  
modem at the same time.
