Chapter 2 – Installing the Modem Before touching anything inside the modem case, discharge any static in your body by touching a piece of grounded metal such as the computer chassis. Electrostatic discharge (ESD) is the release of stored static electricity that can damage electrical circuitry or components. Static electricity is often stored in your body, and discharged when you come in contact with an object of a different potential. Perform the procedure below described in this section only at an ESD workstation using an antistatic wrist strap. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal ground screw (lug). Remove the top part of the modem case. Location of the Jumpers Note: The Speaker Mode jumper is for a modem with the voice option Changing the DialUp/LeasedLine Jumper As shipped from the factory, your modem is configured for normal dial‐up operation. That is, the modem must dial a phone number to connect to another modem. To use the modem on a leased line, you must change jumper J2 to select leased line operation, and J3 to select whether it will be the originating or the answering modem. If dial‐up operation is selected, J3 has no effect. See Chapter 3 for additional leased line information. ● The factory default is the answer position. This makes the modem the answering modem on the leased line. ● To use the modem on a leased line, move the J2 jumper plug from the default dial‐up position to the leased line position. Multi‐Tech Systems, Inc. MT9234ZBA‐Series User Guide 9 ...
Chapter 2 – Installing the Modem ● To make the modem the originating modem on the leased line, move the J3 jumper plug to the originate position. Changing the Voice Jumper The speaker jumper is next to the external speaker jack. ● The factory default position of the voice jumper is set for a stereo speaker or sound card. A jumper plug covers both pins of the jumper. ● To use the modem with a monophonic external speaker, remove the jumper plug from the jumper pins. You can store it by placing it on one jumper pin. Connecting the Modem to Your PC Turn off your computer. Place the modem in a convenient location, and then connect it to your computer’s serial port, the telephone line or leased line, AC power, and, optionally, your telephone.

Chapter 3 – Operation Front Panel Overview The LED indicators on the front panel indicate status, configuration, and activity: TD – Transmit Data. Flashes when the modem is transmitting data to another modem. RD – Receive Data. Flashes when the modem is receiving data. CD – Carrier Detect. 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. OH – Off‐Hook. Lights when the modem is off‐hook, which occurs when the modem is dialing, online, or answering a call. Flashes when the modem pulse‐dials. TR – Terminal Ready. Lights when a communications program is using the modem. It means the modem is ready for an outgoing or incoming call. It goes off when the communications program disconnects the serial port. When it goes off, a connected modem will also disconnect. Power – The Power led lights when the system is applying power to the modem. LeasedLine Operation The MultiModem ZBA modem 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. 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 Open the modem and change jumper J2 to select leased‐line operation, and jumper J3 to select either originate or answer operation, depending upon how you intend to use the modem. See Chapter 2 for the detailed procedure. 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. Turn on the modem. 14 Multi‐Tech Systems, Inc. MT9234ZBA‐Series User Guide ...
Chapter 3 – Operation Connecting to the Internet Your Multi‐Tech modem is your gateway to the Internet and the World Wide Web. To access the Internet and Web via your modem, you must establish a dial‐up account with an Internet service provider (ISP). To locate an ISP near you, look in a local directory or computer publication. Your ISP should provide you with the following information ● User name (also called user ID) ● Password ● Access number (the number you call to connect to the server) ● Host name and/or domain name ● Domain Name Server (DNS) server address If, besides the Web, you use the Internet for e‐mail and newsgroups, your ISP should also provide you with the following information: ● E‐mail or POP mail address ● POP server address ● Mail or SMTP address ● News or NNT server address Multi‐Tech Systems, Inc.

Chapter 4 – Remote Configuration Remote configuration is a network management tool that allows you to configure MultiModem ZBA units 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. Establish a data connection with a remote MultiModem ZBA modem. Send three remote configuration escape characters followed by AT and the setup password, and press . Example: %%%ATMTSMODEM. You have four tries to enter the correct password before being NTER disconnected. If the password is correct, the remote modem responds with OK. You can now send AT commands to configure the remote modem. When you have finished configuring the remote modem, save the new configuration by typing AT&W0 and pressing E . NTER Type ATO and press E to exit remote configuration. You can now break the connection in the normal NTER 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 and possibly also the remote configuration escape character. Changing the Setup Password Open a data communications program such as HyperTerminal. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the MTSMODEM password with xxxxxxxx) and press E . The modem responds with OK if the setup password is correct, NTER and ERROR if it is wrong. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and then press ...
Chapter 4 – Remote Configuration 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. Establish a remote configuration link with the remote modem as described in Basic Procedure. Type ATS9=n, where n is the ASCII code for the new remote configuration escape character, and then press . NTER Save the new value by typing AT&W and pressing E . NTER Type ATO and press E to exit remote configuration. NTER Multi‐Tech Systems, Inc. MT9234ZBA‐Series User Guide 17 ...
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 (Chapter 4). 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 Open a data communications program such as HyperTerminal. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the MTSMODEM password with xxxxxxxx). Press E . The modem responds with OK if the setup password is correct and NTER ERROR if it is wrong. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and then press . The password can include any keyboard character, and can be up to eight characters long. The NTER modem responds with OK. 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. Note: Passwords are case‐sensitive. Turning Callback Security On and Off Callback security must be turned on to enter many callback security commands. Open a data communications program such as HyperTerminal. In the terminal window, type AT#Sxxxxxxxx, where xxxxxxxx is your password. Press E . The modem ...
Chapter 5 – Callback Security Type one of the following commands: To turn off callback security: Type AT#CBS0 and press E . Callers no longer need a password to ● NTER 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 E . With local security ● NTER turned on, you must enter the setup password before you can enter any AT command except the AT, ATIn, and AT#Sxxxxxxxx commands. For a description of remote callback security, see the following paragraph. To turn on remote callback security only: Type AT#CBS2 and press E . With remote callback security ● NTER 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 E . The modem returns to its original setting when you NTER issue the hangup command (+++ATH) or the modem is reset. Note that if a remote modem breaks the connection, callback security remains disabled. Setting Callback Security Message Parity The modem’s password prompt and messages parity must match the parity of the computer to which the modem is connected. Open a data communications program such as HyperTerminal. In the terminal window, type AT#Sxxxxxxxx, where xxxxxxxx is your password. Press E . The modem NTER responds with OK if the setup password is correct and ERROR if it is wrong. 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 E . For odd parity, type AT#CBP1. Press E . ...
Chapter 5 – Callback Security To store a callback phone number in the first memory location, type AT&Z0=[+][‐]ATxxxxxxxx[,???], where xxxxxxxx is the dialing string. Press E . The phone number must be preceded by DT for tone dialing or DP NTER for pulse dialing. The dialing string can also include other AT commands. Example: AT&Z0=+‐ATM0DT5551212. Up to 35 characters can be used. The +, ‐, and ??? characters are optional: + Number entry. Enables a mobile caller to enter his current phone number for callback. ‐ Direct connection. Enables a caller to choose direct connection without being called back. ,??? Extension entry. Must be used with the + command. Enables a caller to enter an extension number for callback. The number of ? characters must equal the number of digits in the extension. To store a callback phone number in the second memory location, type AT&Z1=[+][‐]ATxxxxxxxx[,???], where xxxxxxxx is the dialing string, and press E . Note that the memory location number in the NTER command is incremented by one. Repeat, through memory location 29, until all dialing strings are entered. To review your entries, type AT&V and press E . NTER Note: A form is provided on the last page of this chapter to help you plan or keep track of password and phone number assignments.

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. 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 the power supply and the wall outlet or power strip. ...

Chapter 6 – Troubleshooting ● 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. ● 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. ● 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 swapping modems. If the problem goes away, the first modem is possibly defective. 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. ...

Chapter 6 – Troubleshooting ● 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. ● If the modem reports NO ANSWER, the other system has failed to go off‐hook, or you might have dialed a wrong number. Check the number. ● If the modem reports NO CARRIER, the phone was answered at the other end, but no connection was made. 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 98 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 ...

Chapter 6 – Troubleshooting ● 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. 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 ...
Appendix A – Upgrading the Modem’s Firmware Your modem is controlled by semi‐permanent software, called firmware, which is stored in flash memory. Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off. However, it can be changed by either the manufacturer or the user as bugs are fixed or new features are added. Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few minutes by using the following procedures. Upgrade Overview The upgrade procedure consists of the following steps, which are described in greater detail in the following sections. Identify the model number and firmware version of your modem. Identify the current version of the firmware (you can view this on the Multi‐Tech Web site). If your modem already has the current firmware, there is no need to update it. Download the upgrade file and the appropriate Flash Wizard for your modem. Install the Flash Wizard and extract the firmware .HEX file from the file you downloaded. Document and clear your stored parameters. Upgrade the modem’s firmware using the .HEX file and the Flash Wizard. Restore your parameters. Identifying the Modem Firmware You must know the model number and firmware version of your Multi‐Tech modem to know whether or not you should update it. Run your favorite terminal program.

Appendix E – Using Out of Band Management This appendix describes how to set up routers. The router's console port, for example on a Cisco router, is an asynchronous serial port configured as data communications equipment (DCE). Configuring the Modem for your Country or Region Configure the modem defaults to match the requirements of the country/region in which it will be used. For information on how to do this, see “Configuring the Modem for Your Country or Region“ in Chapter 2. Configuring for Callback Security in Direct Connect Mode Callback security requires a caller to give a correct password before sending data to the system. If you do not plan to use this feature, skip to Step 3. Turning Direct Connect Callback Security On and Off Callback security must be turned on to enter many callback security commands. To turn on callback security: Open a terminal program such as HyperTerminal. Type the command AT#Sxxxxxxxx, where xxxxxxxx is your password (1 to 8 characters long; case‐sensitive). Press E . NTER The modem responds with OK if the setup password is correct and ERROR if it is wrong. The default password is MTSMODEM. If you wish to change the password, then type the command AT#S=xxxxxxxx, where xxxxxxxx is the new password (1 to 8 characters long; case‐sensitive), and press E . NTER Type one of the following commands: To turn on remote callback security only, type AT#CBS2 and press Enter. ● To turn on both local and remote callback security, type AT#CBS1 and press Enter. When local security is ● turned on, you must enter the setup password before you can enter any AT command from a local terminal except the AT, ATIn, and AT#Sxxxxxxxx commands. To store the commands to nonvolatile memory, type AT&W0. Setting the Parity of the Callback Security Messages The modem’s password prompt and messages parity must match the parity of the computer to which the ...
Appendix E – Using Out of Band Management Assigning Callback Passwords To store a callback password for the first callback memory location: Type AT#CBN0=xxxxxxxx where xxxxxxxx is the first password. The password must be unique, must be 6 to 10 characters in length and case‐sensitive, and must not contain a + or ‐ character. Press E . NTER To store a callback password for the second callback memory location, type AT#CBN1=xxxxxxxx. where xxxxxxxx is the second password. Press E . NTER Note: The memory location number in the command is incremented by one. Repeat as many times as necessary until all passwords have been entered. To review your entries: a. Type AT&V b. Press E . NTER To set the modem for direct connect mode: a. Type AT%H1 b. Press E . NTER Calling a Modem Configured for Callback Security Using a terminal program and an originating modem, dial the number of the modem connected to the Cisco router, which we will call the “remote modem.” When connection is established, the remote modem responds: Password> Type a direct connection password, and press E You have three attempts or one minute to enter a valid NTER password. ...
Appendix E – Using Out of Band Management Console Port Final Setup To complete setup: Send the following command string to the modem connected to the console port of the Cisco router: AT%R1&W0 The %R1 command sets E0, Q1, &D0, &K0, $SB9600, and %S1: ● E0 Turns command echo off Q1 Turns result codes off &D0 Ignores DTR from the DTE &K0 Selects no flow control $SB9600 Sets the serial baud rate to 9600 bps. %S1 Disables command mode at all serial speeds except 115200 bps. The &W0 command stores the commands to memory. ● The modem is now configured for use on the Cisco router console port. Note that command echo and result codes have been turned off. If you need to send additional AT commands to the modem after configuring it, the modem provides little feedback that it has received and acted upon the command. Only commands such as ATI0 that request specific data from the modem send any data to the DTE as an indication that the modem has accepted the command. Temporarily turning on command echo and result codes might make it easier to reconfigure the modem. When the modem is connected to the console port, turn the modem off and then on again. This will set the serial baud rate to 9600 bps as the $SB9600 command is implemented. Console Port Connections To connect a personal computer to the console port, use the RJ‐45‐to‐RJ‐45 roll‐over cable and either the RJ‐45‐ to‐DB‐25 female DTE adapter or the RJ‐45‐to‐DB‐9 female DTE adapter (labeled “TERMINAL”). Cable Pin‐outs and Cabling Guide Console Modem ...
Appendix E – Using Out of Band Management Remote Configuration Configuring the modem results in core settings that allow the modem to function properly on the console port of the Cisco router. You can use commands described in this section to remotely call into the MT9234ZBA attached to the console port with another modem. Note: Setting country/region configuration and turning on callback security cannot be done remotely. Nor can all commands be executed remotely if the remote modem is set for callback security. Remote configuration of a modem configured this way is not recommended. Establish a data connection with a remote MT9234ZBA modem. Send three remote configuration escape characters followed by AT and the setup password, and then press . NTER Example: %%%ATMTSMODEM. You have four tries to enter the correct password before being disconnected. If the password is correct, the remote modem may respond with OK. Note: If the modem has previously been configured with command echo off and result codes off, it may be difficult to determine if the remote modem is responding to commands. The ATI command can be used for this purpose. Even with echo and result codes off, the modem will respond with the requested ID string if it is properly receiving the command. You can now send AT commands to configure the remote modem. When you have finished configuring the remote modem, save the new configuration by typing AT&W0<CR>, then type ATO<CR> to exit remote configuration. You can then break the connection in the normal way. Note: This step is important to ensure that the connection is broken cleanly. Multi‐Tech Systems, Inc. MT9234ZBA‐Series User Guide 45 ...
