Chapter 2 - Installation

This chapter shows you step-by-step how to set up your Multi-Tech data/fax/voice modem and make your first calls.

Safety Warnings

• Use this product only with UL- and CUL-listed computers (U.S.A. and Canada)

• To reduce the risk of fire, use only 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.

Step 1: Mount the Feet

Step 2: Change the Internal Jumpers

This step is required only if:

Ö You intend to use the modem on a leased line. Ö You intend to add a monophonic external speaker to your modem with the voice option. No

changes are needed for stereo.

This will require you to open the modem and move one or more jumpers on the modem’s printed circuit board.

Warning: The following procedure must be performed by authorized service personnel. Caution: The circuit board can be harmed by static electricity. Before you open the case, touch a

grounded object, such as the metal chassis of your computer, to discharge any static electricity in your body, then touch the metal shell of the modem’s RS-232 connector to ensure that there is no voltage difference between you and the modem.

Opening the Modem

1. If the modem is connected, turn it off and remove all connecting cables, including the power and line cables.

2. Turn the modem upside down.

3. On the bottom of the modem are two screws, which hold the case together. Remove both screws and set them aside.

4. Turn the modem right side up.

5. Remove the top part of the modem case.

6. To close the modem, reverse Steps 1–5.

Changing the Dial-Up/Leased-Line Jumpers

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 J10 to select leased line operation, and J11 to select whether it will be the originating or the answering modem. If dial-up operation is selected, J11 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 J10 jumper plug from the default dial-up position to

the leased line position.

· To make the modem the originating modem on the leased line, move the J11 jumper plug to the

originate position.

Changing the Voice Jumper

The speaker jumper (J8) is next to the external speaker jack (see Figure 2-2).

· 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 J8 jumper.

· To use the modem with a monophonic external speaker, remove the jumper plug from the J8

jumper pins. You can store it by placing it on one jumper pin.

Connect the Modem to a Phone (Optional)

If you want to connect a phone to same line as the modem, plug it into the modem’s PHONE jack.

Important: The PHONE jack is not interchangeable with the LINE jack. Do not plug the telephone into the LINE jack or the line cable into the PHONE jack.

Connect a Microphone and/or Speakers (Optional)

PWR RS232 PHONE LINE

Figure 2-4. MultiModemZBAV connections.

Connect the Microphone

For voice mail or speakerphone applications, plug an unamplified microphone into the MIC jack on the side of the modem. The microphone should have a stereo 1/8-inch mini plug. Do not use a monophonic microphone.

Connect the Speakers

For speakerphone or voice mail applications, use a 1/8-inch plug male-to-male stereo patch cord to connect the SPKR jack on the side of the modem to the LINE IN jack on your sound card. If your sound card does not have a LINE IN jack, use its MIC jack. The stereo male-to-male patch cord can be purchased at a local PC retail store.

If you do not have a sound card, you can plug an unamplified speaker directly into the SPKR jack.

Connect the Modem to the AC Power Outlet

The power switch is located on the right side of the modem. Make sure it is set to OFF. Plug the the universal power supply into the PWR jack on the modem. Then plug one end of the country-specific power supply cord into the universal power supply and the other end into a power outlet or power strip.

Note: Use only the power supply supplied with the modem. Use of any other power supply voids the warranty and can damage the modem.

Page 15

MultiModemZBA-V-V92 User Guide

2 Installation

Power-On Test

Test the modem by turning it on. When you turn it on, the modem performs a diagnostic self-test, after which the 56 indicator should light. 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 Chapter 8, “Solving Problems.”

Surge Protectors and Lightning

Your modem has automatic, self-resetting protection to protect it from lightning-induced electrical spikes on the telephone line. Nonetheless, large power surges and nearby lightning strikes can damage or destroy your modem. Therefore, we recommend that you plug the modem into a surge protector rather than directly into a wall outlet, preferably a surge protector that provides protection against electrical spikes on the telephone line as well as on the power line. Note that not even a surge protector can guard against damage from a nearby lightning strike. During an electrical storm, it is safest to unplug your computer equipment from both the power outlet and the telephone line.

Step 4: Install the Modem Driver

If you use Windows 95 or above, you must install the modem driver. The modem driver tells Windows how to control the modem. In Windows 95 and above, the MTMoh Modem on Hold program is installed at the same time (see Chapter 7). If you use a Linux operating system, please see Appendix F. If you use another operating system, please refer to its documentation for modem installation information.

Installing 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 Chapter 8, “Solving Problems.”

2. Insert the system CD into your CD-ROM drive, and then click OK.

3. Windows installs the modem driver.

4. Click Finish to exit.

Removing an Old Modem Driver

When a new modem replaces another modem, the old modem driver remains in Windows, and the old modem driver is still selected in HyperTerminal and other Windows applications. Though 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 driver from Windows.

1. Click the Start button, point to Settings, and click Control Panel.

2. Double-click the Modems icon to open the Modems Properties dialog box.

3. In the list box, select the old modem.

4. Click Remove, and then click Close.

5. The next time you dial a HyperTerminal connection, it will select your new modem and ask you to

confirm the selection.

Step 5: Configure the Modem for Your Country

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 in which you are using it. You must also do this if you move the modem to another country after it has been configured for the first country. You can use one of two configuration methods:

1. Use the Global Wizard to Configure Your Modem

2. Use AT Commands to Configure Your Modem

Using the Global Wizard to Configure Your Modem

The Global Wizard configuration utility is recommended for computers running Windows 95 or newer.

1. Insert the MultiModemZBAV-V92 CD into the CD-ROM drive. The Autorun menu should appear.

2. Click Initial Setup and Country 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 hard drive for future use.

4. The Global Wizard dialog box appeard. Click Next.

5. The Global Wizard searches for your modem and identifies it. Click Next.

6. Select the country in which the modem will be used. Click Next.

7. Review your choice of country. 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 to Configure Your Modem

Non-Windows users can configure the modem using AT commands. You must enter these commands in your communication program’s terminal window.

1. Run your favorite communication program, and open the program’s terminal window.

2. To configure the modem for a specific country, type AT%T19,0,nn, where nn is the country code in hexadecimal notation, and then press ENTER. The message OK displays.

3. To verify the change, type ATI9 and press ENTER. The country code displays in decimal format.

Country AT Command (hexadecimal) Result code (decimal)

Euro/NAM AT%T19,0,34 (default) 52

A complete list of country codes can be found on the Multi-Tech Web site at

Step 6: Install and Configure Your Software

You may use either the communication program included with your modem or a third-party program. Communication programs designed for Windows 95 and above normally do not need to be manually configured, since they obtain configuration information from Windows. Communication programs designed for DOS and other operating systems, however, may need to be manually configured to work with your modem. Though each communication program is different, the following procedure should work with most of them.

1. Install and run your communication program.

2. Find the dialog box or menu that lets you select your modem. (In Windows Terminal select

3. Choose your modem from the program’s modem list. If it isn’t listed, choose a generic modem

and modify the settings as necessary.

4. Change the modem initialization string, if necessary. The factory default configuration works well

for most purposes. To load the factory default configuration, use AT&F. To load a custom configuration that was saved using the & string should include the &D0 command. If you do not want the modem to always answer the phone, add S0=0 to the string. To use Caller ID with the modem, add S0=2 to the string (Caller ID information is sent between the first and second rings, so the phone must ring at least twice befor the modem picks up the line). Depending on the software, you might have to end the string with a carriage return character (^M).

Note: To change the modem’s default configuration, type new commands in the communication program’s terminal window, adding the &W command to store them in the modem’s nonvolatile memory. For instance, to create a default configuration that turns off autoanswer, type AT&FS0=0&W. The new configuration loads automatically whenever the modem is turned on or receives the ATZ command.

command, use ATZ. For a Macintosh, the initialization

5. Select the port the modem is connected to (normally COM1 or COM2).

6. Select your serial port speed. This can be labeled “maximum speed,” “DTE bps,” or “baud rate.”

Ideally, if you use data compression, you should set your serial port baud rate to four times the modem’s maximum transmission speed or faster; however, few files can be compressed enough to require speeds that high, and not all serial ports can handle speeds that high.

7. If the communication program has an autobaud selection, make sure it is disabled. Autobaud applies

only to older modems, and can cause problems if enabled.

8. If the program allows you to edit the no-connect messages (

The MultiModemZBA-V-V92 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; 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. Open the modem and change jumper J10 to select leased-line operation, and jumper 11 to select

either originate or answer operation, depending on how you intend to use the modem. See Chapter 2 for the detailed procedure.

2. Connect a modular telephone cable to the LINE jack. Connect the other end of the cable to a

two-wire leased line jack or terminals supplied by the telephone company.

3. Turn on the modem.

4. This completes the setup for two-wire leased line operation. Upon completion, the modem

attempts to connect to the modem at the other end of the leased line. If the remote modem has not yet been configured for leased line operation, you may turn off the local modem until the remote one is ready.

V.92 Operation

Because the V.92 protocol is new and still largely unsupported by central servers, some features are disabled by default in the initial release of the MT5634ZBA-V-V92 modem. This section describes the status of the V.92 features in the initial release. Please note that the V.92 special features require connection to a V.92-capable server.

 General. The V.92 protocol is enabled by default. If the MultiModemZBA-V-V92 detects another

V.92 modem during the handshake phase, they will connect in V.92 mode; otherwise, they will connect in V.90 mode or the highest mutually acceptable mode. The AT command that controls this is +MS=.

 Commands. AT commands specific to the V.92 protocol and the new V.44 compression protocol

begin with the plus character (+). These commands are in this manual. Also, the S109 register has been modified to support V.92.

 PCM Upstream. PCM Upstream is disabled by default. To upload files at speeds above 33.6

kbps, you must enable PCM Upstream using the command +PIG=1. Please note that this requires connection to a V.92-capable server. Also, please note that since upload speeds are affected by line conditions, meeting the previous requirements cannot guarantee speeds above 33.6 kbps.

 Quick Connect. Quick Connect, which shortens the handshake time with another V.92 modem, is

disabled by default. To enable it, use the command +PQC=0. Quick Connect speeds connect times by skipping the line test during the handshake and using the configuration from the last data connection. Quick Connect works best when line conditions are consistent from call to call. If line conditions are variable, enabling Quick Connect can actually increase the connect time slightly.

 Modem on Hold. Modem on Hold enables you to put a V.92-capable server on hold while you

take another call (see Chapter 7). Modem on Hold operation is possible only with the MTMoh Modem on Hold program included with the MT5634ZBA-V-V92. MTMoh is initially supported only on Windows 95, 98, and Me. However, Windows NT, 2000, and XP support is expected soon, and may be available by the time you receive your modem.

Firmware updates for the MT5634ZBA-V-V92 can be downloaded from http://www.multitech.com/ SUPPORT/MultiModemZBA/firmware.asp. Please see the Appendix for update instructions. MTMoh updates can be downloaded from http://www.multitech.com/SUPPORT/software/.

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

3 Operation

Dial-Up Networking

Before you can connect to the Internet, you must set up a remote-node client program on your computer. The Windows version is called Dial-Up Networking. Dial-Up Networking establishes your connection to the ISP’s server, which is the shared computer that manages calls from clients (your computer) to the Internet. Most, if not all, Windows browsers start Dial-Up Networking automatically when you open them.

For instructions on how to set up Dial-Up Networking, consult your ISP or your operating system’s online help or printed documentation. Many ISPs include with their service a program that will install and configure Dial-Up Networking automatically for you.

Sending a Fax

You can use the PhoneTools program included with your modem to send and receive faxes directly from your computer. The following procedure uses print capture, which enables you to fax a document directly from the Windows application in which you created it without opening PhoneTools.

1. Install PhoneTools if it is not already installed.

2. Create a document in a Windows application, such as a word processor, graphic editor, or

spreadsheet. To fax the document, keep the document open and select the Print command from the File menu.

3. Select CAPTURE FAX +BVRP as the printer driver, and then click OK. The Send Fax wizard

appears.

4. In the Recipient section, type the required information or extract it from the Phone Book by

clicking

5. In the Template section, optionally select a cover page and type a cover message.

6. Select the document to be sent. The default file when sending from within a Windows application

is Capture.dgr.

7. Select the date and time to send the document, if you do not want to send it immediately.

8. Click Finish to start the transmission.

Chapter 4- AT Commands, S-Registers, and Result Codes

AT commands are used to control the operation of your modem. They are so called because each

command must be preceded by the characters AT commands can be issued only when the modem is in command mode or online command mode.

The modem is in

connected to another modem. To put the modem into online command mode from data mode, you must issue an e.g., +++ATH to hang up the modem. To return to data mode from online command mode, you must issue the command ATO.

To send AT commands to the modem you must use a communications program, such as HyperTerminal or the PhoneTools communications program included with your modem. You can issue commands to the modem either directly, by typing them in the terminal window of the communications program, or indirectly, by configuring the operating system or communications program to send the commands automatically. Fortunately, communications programs make daily operation of modems effortless by hiding the commands from the user. Most users, therefore, need to use AT commands only when reconfiguring the modem, e.g., to turn autoanswer on or off.

5 Remote Configuration

Chapter 5 - Remote Configuration

Remote configuration is a network management tool that allows you to configure MT5634ZBA 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 are valid regardless of whether the connection is established by the local or the remote Multi-Tech modem.

Note: For this procedure, 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 MT5634ZBA 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. Type 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.

CAUTION: If you hang up while you are in remote configuration mode, the modem may lock up.

Setup

Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who has the bly also the remote configuration escape character.

To Change the Setup Password

1. Open a data communications program such as HyperTerminal or PhoneTools.

2. In the terminal window, type AT#SMTSMODEM (or AT#S

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.

5 Remote Configuration

To Change 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 E

3. Save the new value by typing AT&W and pressing E

6 Callback Security

Chapter 6 - 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.

Setup

Your modem was shipped with a default setup password (MTSMODEM). The same password is used for both callback security and remote configuration (Chapter 5). Because anyone who has access to this guide has access to the default password, you should change the password during your initial setup.

To Change the Setup Password

1. Open a data communications program such as HyperTerminal or PhoneTools.

2. In the terminal window, type AT#SMTSMODEM (or AT#S MTSMODEM password with setup password is correct, and

3. To change the password, type AT#S= then press ENTER. The password can include any keyboard character, and can be up to eight characters long. The modem responds with OK.

7 Modem on Hold Operation

Chapter 7 - Modem on Hold Operation

What Is Modem on Hold?

Your modem supports a feature called Modem on Hold when it is in V.92 mode. Modem on Hold works with your telephone company’s Call Waiting service to put a remote modem “on hold” while you answer a voice call. When you finish your conversation and hang up, the previous connection resumes, providing you have not exceeded the time limit. Among other things, this feature eliminates the problem of the modem disconnecting if someone calls you while Call Waiting is enabled.

For this feature to work, you must have Call Waiting service from your telephone company. Also, the remote modem (for example, the modem used by your internet service provider) must support V.92 and Modem on Hold. The duration of the hold time is controlled by your ISP.

Note: MTMoh, the Modem on Hold program included with your modem, currently supports only Windows 95, Windows 98, and Windows Me. Future versions are expected to support Windows NT, Windows 2000, and Windows XP. Please check http://www.multitech.com/SUPPORT/software/ for updates.

The Modem on Hold Program

Modem on Hold operation is controlled through the MTMoh program, which is automatically installed when you install the modem driver. A shortcut icon for MTMoh is placed on the Windows desktop. You can start MTMoh by double-clicking this icon, or you can make MTMoh start each time Windows starts by moving the icon to the Windows StartUp folder.

To move the MTMoh icon to the StartUp folder, right-click on the Start button, choose Explore, expand the Programs folder to reveal the StartUp folder, and then drag the MTMoh icon onto the StartUp folder.

When MTMoh is running, the MTMoh icon appears in the Windows system tray:

Right-click on the icon to open the MTMoh menu:

Chapter 8 - Solving Problems

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 (see Appendix D).

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.

Ö Make sure the modem’s power switch is on, especially if you normally turn the modem on by

turning on a power strip.

Ö If the modem is plugged into a power strip, make sure the power strip is plugged in and its power

switch is on.

Ö 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.

Ö If the power strip is on and the modem switch is on, try moving the power supply to another

outlet on the power strip.

Ö Test that the outlet is live by plugging another device, such as a lamp, into it. Ö 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

Ö Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”) Ö 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.)

Ö Make sure you are in terminal mode in your data communication program, then type AT and

press E problem likely is in the connection setup in your communication software.

Ö 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.

Ö 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.

Ö Your communication software settings may not match the physical port the modem is connected

to. 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.

Ö 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.

Ö 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.

Ö 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.

Multi-Tech modem, try swapping modems. If the problem goes away, call Technical Support for assistance (see Appendix D).

8 Solving Problems

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.

Ö If the modem reports

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 (note, however, that X3 is not allowed in some countries, such as France and Spain).

Ö If the modem reports BUSY, the other number might be busy, in which case you should try again

later, or it might indicate that you have failed to add a 9, 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.

NO DIALTONE

, check that the modem’s telephone line cable is connected

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.

Ö If the modem reports

tion 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.

Ö Poor line conditions can affect the connection. When using V.34 or V.32 client-to-client connec-

The Modem Disconnects While Online

Ö 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.

To learn more about Modem on Hold, see Chapter 7.

Ö 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.

Ö Check for loose connections between the modem and the computer, the telephone jack, and AC

power.

Ö 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.

Ö 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.

The Modem Cannot Connect When Answering

Ö 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 Chapter 4. For information on changing the modem’s default configuration, see “Step 6: Install and Configure Your Software” in Chapter 2.

Ö 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

Ö If you are using a slow transfer protocol, such as Xmodem, try Zmodem or Ymodem/G instead. Ö 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.

Ö 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.

Ö 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.

Ö 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.

Ö 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

Ö 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.

Ö Make sure the flow control method you selected in software matches the method selected in the

modem. If you are using the modem with a Macintosh, you might have the wrong cable for hardware flow control.

Ö 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

Ö 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.

Ö 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.

Ö 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.)

Ö 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

Ö 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).

Ö Make sure that you have Caller ID service from your telephone company.

Fax and Data Software Can’t Run at the Same Time

Ö Communication devices can be accessed by only one application at a time. Under DOS or Win-

dows 3.1x, you can run either your fax software or your data communications software, but not both at the same time, unless you have a special communication device management application. 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.

C Upgrading the Modem’s Firmware

Appendix C - Upgrading the Modem’s Firmware

Introduction

Your modem is controlled by semi-permanent software, called 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.

firmware

, which is stored in flash

Upgrade Overview

The upgrade procedure consists of the following steps, which are described in greater detail in the following sections.

1. Identify the model number and firmware version of your modem.

2. Identify the current version of the firmware at the Multi-Tech Web site or BBS. If your modem already has the current firmware, there is no need to update it.

3. Download the upgrade file and the appropriate Flash Wizard for your modem.

4. Install the Flash Wizard and extract the firmware .HEX file from the file you downloaded.

5. Document and clear your stored parameters.

6. Upgrade the modem’s firmware using the .HEX file and the Flash Wizard.

7. Restore your parameters.

Step 1: Identify 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.

1. Run your favorite terminal program. If you are using Windows 95 or above, you can use Windows HyperTerminal.

2. In the program’s terminal window, type AT&F. Even if you cannot see the AT&F command on your screen, be sure to type it completely, and then press ENTER. If the modem does not respond with OK, repeat the AT&F command.

3. Now type ATI, press ENTER, and record your results. The model number and firmware version should appear similar to that shown below.

C Upgrading the Modem’s Firmware

Step 2: Identify the Current Firmware Version

Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has the current firmware, there is no need to update it.

1. Using your favorite Web browser, go to http://www.multitech.com/SUPPORT/MultiModemZBA/ firmware.asp.

2. Scroll down to your modem model number.

3. Look at the firmware version number for your modem.

4. If the firmware version number matches the firmware version number found in “Step 1: Identify the Modem Firmware,” you have the current firmware version and do not need to be update.

5. If the firmware version number is greater than the firmware version number found in “Step 1: Identify the Modem Firmware,” your modem has an older firmware version. Continue with “Step 3: Download the Upgrade File.”

Warning: The first digit of the new firmware must match the first digit of the old firmware, or the modem may not work properly. E.g., if your current firmware version is 4.16, replace it only with

4.xx firmware, not 6.xx firmware.

Step 3: Download the Upgrade File

1. If you are not already at the MultiModemZBA Firmware page of the Multi-Tech Web site, follow the procedure in “Step 2: Identify the Current Firmware.”

2. Download the upgrade file for your modem by clicking its name, and save the file in a temporary folder on your hard disk.

3. In the same section of the Web page, click the Flash Wizard utility for your operating system to download it, and save it in the same folder.

Step 4: Extract the Upgrade Files

1. Install the Flash Wizard utility by double-clicking the file name in Windows Explorer.

2. Extract the upgrade files by double-clicking the file name. The extracted files include a .HEX file, which contains the upgrade data, and a Readme file.

3. Copy the upgrade .HEX file into the Flash Wizard folder, which, in a default installation, is at C:\Program Files\MultiTech Systems\Flash Wizard\.

Step 5: Clear Your Stored Parameters

Before you flash your modem, you should record the parameters that are currently stored in it, so you can reprogram it after flashing. After you have recorded them, send the AT&W1Z command to the the modem to clear the stored parameters.

1. Run your favorite terminal program. If you are using Windows 95 or above, you can use Windows HyperTerminal.

2. In the program’s terminal window, type AT&V and press ENTER to list your modem’s current parameters.

3. Record your parameters by saving the screens and sending them to your printer.

4. Type AT&W1Z and press ENTER to clear your stored parameters and reset your modem to factory default.

5. Close the terminal program.

Step 6: Upgrade the Modem’s Firmware

Before you begin the following procedure, read the README.TXT file extracted from the upgrade archive file. Note the file name for the new firmware (example: ARQG125A.HEX).

WARNING: Never install an older version of firmware over a newer version. Doing this WILL DESTROY THE FLASH PROM! If the flash PROM is destroyed, the modem must be sent in for repair.

1. Run Flash Wizard by double-clicking its icon or file name, or by selecting it from the Start menu. The Identifying Devices dialog box is displayed as Flash Wizard locates and identifies the de- vices connected to your system.

Note: If the message turned on and that all cables are correctly and securely attached.

2. Click the modem to be upgraded, and then click Next to proceed.

3. Select the port to be upgraded from the Port list, select the appropriate .HEX file from the Hex

File list, and then click Next to continue. Note: Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.

4. The Progress dialog box appears, showing a status bar that indicates the progress of the up- grade.

Caution: Any disruption of the program during this stage of the upgrade can cause your modem to become inoperable. Wait for the Next button to become active before proceeding.

5. When the flash upgrade is complete, the message to continue.

Appendix D - Installing a Modem Under Linux

Introduction

This appendix explains how to install a modem on a computer operating under the Red Hat Linux 6.2 operating system. Other versions of Red Hat and other Linux operating systems should be similar. Briefly, in Linux, you do not need drivers for most standard external modems and most internal ISA bus modems. Programs in Linux commonly call upon the port, rather than the modem.

Standard Linux Serial Port Definitions

PC port Linux port Com1 ttyS0 Com2 ttyS1 Com3 ttyS2 Com4 ttyS3

Installation

Connect the external modem to an available serial port.

Setup

This section describes how to make sure Linux can talk to the modem and be able to dial up to the Internet. Linux can use different programs and desktops depending on who made the Linux operating system and what version it is. The following procedures use the most commonly installed components of Red Hat 6.2. More information can be found in your Linux OS owner’s manual.

Using the Terminal Program Minicom to Verify Operation

1. At the command prompt, type minicom –s and press ENTER.

2. Select Serial port setup and press ENTER.

3. From Serial port setup, use the A key to access Serial Device, and then press ENTER.

4. Press ESC.

5. You are now in the Minicom terminal. Type AT and press ENTER. The screen should display OK to

verify the operation. Alternately, dial a phone number to verify line operation

6. To leave Minicom, press CTRL + A, and then press Z.

7. On the help menu, press X to exit.

Using the Modem to Call the Internet

Linux allows different graphic user interfaces (GUI). In the following steps, we’ll use the Gnome Desktop GUI and assume that the Internet Service Provider (ISP) you are calling assigns you the Domain Name Service (DNS) and Internet Protocol (IP) addresses. For more information on DNS or IP, see the Linux OS owner’s manual or contact your ISP.

1. On the Task Bar at the bottom of the screen, select the Gnome Footprint.

2. Select Internet from the menu.

3. Select Dialup Configuration Tool.

4. Select Add, and then click Next.

5. Enter the connection name and phone number, and then click Next.

6. Enter your user name and password, and then click Next.

7. Select Normal ISP if your ISP is not listed, and then click Next.

8. Click Finish.

Calling the ISP

1. On the Task Bar at the bottom of the screen, select the Gnome Footprint.

2. Select Internet from the menu.

3. Select RH PPP Dialer.

4. Select the connection name you entered in step 5 of the previous section.

5. Click OK.

Answering Calls

To use the system for answering calls, Linux requires other programs to be installed, such as Mgetty, Mgetty+Sendfax, and others, depending on your requirements. Each vendor of Linux has more than adequate information on installing these programs.

E Connecting to a Cisco Router

Appendix E - Connecting to a Cisco Router

This appendix provides information on how to connect an MT5634ZBA-V-V92 modem to a Cisco® router.

Connecting to a Cisco Router Console Port

The console port on the Cisco IOS® router is an asynchronous serial port configured as data communications equipment (DCE). For Cisco 1000, 1600, 2500, 2600, and 3600 series routers, the console port uses an RJ-45 connector.

WARNING: Do not connect the modem to the Cisco router’s auxiliary port. This procedure and document apply only to the Cisco router’s console port.

Step 1: Configure the Modem for your Country

Configure the modem defaults to match the requirements of the country in which it will be used. For information on how to do this, see “Step 5: Configure the Modem for your Country” in Chapter 2.

Step 2: Configure 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.

Note: Setting the modem for callback security in direct connect mode disables the remote configuration feature of the modem.

To Turn Direct Connect Callback Security On and Off

Callback security must be turned on to enter many callback security commands.

1. Using a terminal program such as HyperTerminal, type the command AT#S

xxxxxxxx OK

MTSMODEM . If you wish to change the password, then type the command AT#S=

is the new password (1 to 8 characters long), and press ENTER.

2. Type one of the following commands:

is your password (1 to 8 characters long), and press ENTER. The modem responds with

if the setup password is correct, and

ERROR

if it is wrong. The default password is

xxxxxxxx

 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#S

3. Type AT&W0 to store the above commands to nonvolatile memory.

Note: For other callback security modes of operation, see Chapter 6.

E Connecting to a Cisco Router

To Set the Parity of the Callback Security Messages

The parity of the modem’s password prompt and messages must match the parity of the computer to which the modem is connected.

1. The default parity setting for your modem is no parity (AT#CBP0). To change the modem’s prompt messages to use even parity, type AT#CBP2 and press ENTER. For odd parity, type AT#CBP1 and press E

2. To store the new parity value, type AT&W and press ENTER.

NTER.

To Assign Callback Passwords

1. To store a callback password for the first callback memory location, type AT#CBN0= where

xxxxxxxx

six to ten characters in length, and must not contain a + or - character.

2. To store a callback password for the second callback memory location, type

AT#CBN1=

4. To review your entries, type AT&V and press ENTER.

5. To set the modem for direct connect mode, type AT%H1 and press ENTER.

To Call a Modem Configured for Callback Security

1. 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.”

2. When the connection is established, the remote modem responds with the following message:

Password>

3. Type a direct connection password, and press ENTER. You have three attempts or one minute to enter a valid password.

4. If the password is valid, the message working connection.

OK Connecting

appears, and the modems establish a

Step 3: Console Port Final Setup

Send the following command string to the modem being connected to the console port of the Cisco router:

AT%R1&W0

The %R1 command sets E0, Q1, &D0, &K0, $SB9600, and %S1, and the &W0 command stores the commands to memory. The %R1 command sets the following functions:

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 modem is now configured for use on the Cisco router console port.

Page 92

MultiModemZBA-V-V92 User Guide

Note that command echo and result codes have been turned off. If it becomes necessary to send additional AT commands to the modem after it has been so configured, there will be little feedback from the modem that it has received and acted upon the command. Only commands such as ATI0 that request specific data from the modem will 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 ease reconfiguration of 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.

E Connecting to a Cisco Router

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”).

Remote Configuration

The configuration of the modem described in Step 3 contains the core settings that allow the modem to function properly on the console port of the Cisco router. Commands in this section may be done remotely by calling into the MT5634ZBA-V92 attached to the console port with another modem.

Note: Setting country 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 so configured is not recommended.

1. Establish a data connection with a remote MT5634ZBA-V92 modem.

2. Send three remote configuration escape characters followed by AT and the setup password, and then press ENTER. 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.

3. You can now send AT commands to configure the remote modem.

Page 93

MultiModemZBA-V-V92 User Guide

4. 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.
