2. Overview

The V.92 Dialup 2-Wire or 4-Wire Leased-Line Data/Fax Modem supports two- or four-wire leased lines. Since leased-line operation uses two client modems connected to each other, the maximum leased-line data rate is

33.6 kbps.

The modem offers interactive automatic dialing. You can store four command lines or telephone numbers of up to 30 characters each in the modem’s nonvolatile memory. The modem pulse- or tone-dials, and recognizes dial tones and busy signals for reliable call-progress detection. It can also detect AT&T

calling-card tones. It is

FCC-registered for connection to telephone networks without notification to the telephone company.

The modem’s front panel includes a liquid crystal display (LCD) and four buttons, which together can be used to either display the current connection status of the modem or to configure the modem. The modem also can be configured through standard AT commands; these appear in the AT Commands Reference Guide that’s included on the system CD that accompanies your system.

Additional features include:

• Complies with major international standards to ensure compatibility with other modems.

• Uses DTMF and tone detection to distinguish data and fax calls when used with software that supports these features.

• Supports serial port speeds to 230.4 kbps with compatible serial ports.

• Supports automatic fallback to slower speeds in noisy line conditions, and fall-forward to faster speeds as conditions improve.

• Supports both synchronous and asynchronous data transfer.

• Supports callback security and remote configuration.

• Supports AS/400

applications.

• Automatically disables compression when transferring already-compressed files.

• Can autodial, redial, pulse (rotary), and touchtone dial.

• Detects dial tones and busy signals for reliable call-progress detection.

• Supports plug-and-play (PnP) operation.

• Can be flash upgraded.

• Supports V.17, Class 1, Class 2 (V.92), and Group 3 fax standards, allowing it to communicate with other fax modems as well as fax machines.

5. Leased-Line Operation

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 a line and are powered 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.

The modem supports both two- and four-wire leased-line operation. For more information, see Sections 5.1 and

5.2.

If the data line or power is interrupted, leased-line modems automatically switch to a dialup connection. For more information, see Section 5.3.

5.1 Two-Wire Setup

1. For two-wire leased-line operation on the V.92 Dialup 2-Wire or 4-Wire Leased-Line Data/Fax Modem, connect the provided modular telephone cable to the LINE jack. Connect the other end of the cable to the two-wire leased-line jack or terminals supported by the telephone company.

This completes the setup for four-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.

5.3 Dial Backup and Leased-Line Restoral Setup

For leased-line operation, the modem has a dial backup capability in which the modem is connected to a standard dialup line as well as to the leased line. If the leased line fails, the originate modem automatically dials and connects to the answer modem through the standard telephone network. While it is in dial backup mode, the modem periodically checks the leased line to see if it is operational. If the line is operational, the modem then attempts to restore the leased line. If the modem detects that it is not connected to the standard telephone network when the leased line fails, it immediately switches to leased line restore.

The dial-back timer, register S17, determines how long the modem waits after a leased line failure before it attempts a dial backup connection. The S17 default setting is one minute. During that minute, the originate modem tries to establish the leased line link. If the leased line is established during that time, the S17 timer is cleared and everything is back to normal. If the timer expires, the modem attempts a dial backup connection. The timer’s purpose for the answer modem is to determine when it can accept a dialup call. Dial-back starts only when both timers have expired and the leased line is still down.

The restore timer, register S15, determines how frequently restore attempts occur when the modems are in dial backup mode. S15 can be set from 10 to 255 minutes in one-minute increments. A value of 0 disables dial backup. The default value is 30 minutes.

NOTES

Set register S15 identically on the local and remote modems.

Remote password:

3. Type the remote configuration password, then press Enter. The default is BLACKBOX. It is not case-sensitive.

• If the password is incorrect, the word CONNECT appears, and the local modem returns to online mode.

• If the password is correct, an >AT command prompt appears.

4. Type AT commands to configure the remote modem. You don’t have to precede the commands with “AT.”

5. When you have finished configuring the remote modem, type *E and press Enter to exit remote configuration mode and return to online data mode. You can now break the connection in the normal way.

NOTE

The dialing command is not allowed in remote configuration mode.

6.2 Extra Security Measures

6.2.1 CHANGING THE REMOTE CONFIGURATION PASSWORD

The modems are shipped with a default setup password, which is BLACKBOX (not case-sensitive). Because anyone who has an owner’s manual knows the default setup password, for security reasons you should change the password and the remote configuration escape character.

The remote configuration password can be changed only from the modem’s front panel.

1. Turn on the modem.

2. Starting at the STATUS LCD, press ↓, ↓, ↓, →, →, ↓, → to access the ENTER PASSWORD LCD.

STATUS =

→, ↓

V.92 DIALUP 2-WIRE OR 4-WIRE LEASED-LINE DATA/FAX MODEM USER’S GUIDE

3. To change the password, press ↑← or ↓ to select the first character of the password, then press → to go to the next character. Repeat until you have entered the entire password.

4. To cancel the new password, press → until the password is erased. To save the new password, press the

Enter button. The next time you remotely configure the modem you must use the new password.

6.2.2 C

HANGING THE

REMOTE ESCAPE CHARACTER

To improve security, you can change a remote modem’s remote configuration escape character. The remote configuration escape character is stored in register S13. The factory default is 42, which is the ASCII code for the asterisk character (*). Setting S13 to 0 (zero) disables remote configuration entirely-—but 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 Section 6.1.

2. Type ATS13=n, where n is the ASCII code for the new remote configuration escape character. Press Enter.

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

4. Type ATO<CR> to exit remote configuration.

CHAPTER 7: Callback Security

7. Callback Security

Callback security protects your network from unauthorized access and helps control long distance costs. When callback security is enabled, all callers must enter a password. If the password is invalid, the caller can try twice more before the modem hangs up. If the password is valid, the modem hangs up and returns the call by dialing the phone number associated with the password.

You can implement password protection without callback by storing a hyphen (-) before the callback phone number. The caller must then append a hyphen to his password to establish the direct connection.

The modem can store up to 30 callback phone numbers and 30 callback passwords. Phone numbers can be up to 30 characters long and can contain the pause (,) and wait (W) characters in addition to the digits and characters normally found on a touchtone keypad. Passwords can be up to 10 characters long.

Callback phone numbers are associated with callback passwords by being assigned to the same callback memory location. For example, if you assign the password “APRICOT” to memory location 16 and, in a separate operation, also assign phone number 6127853000 to memory location 16, the modem calls phone number 6127853000 when it receives the password “APRICOT.”

Because there is no way to examine the passwords and phone numbers stored in the modem, write them down as you enter them. A sample form appears on the last page of this chapter.

7.1 Setup Procedures

TURNING CALLBACK SECURITY ON AND OFF

Autoanswer must be enabled (S0=1 or S0=2) for callback security to work.

AT Command Method

7.4 Calling Procedure

Use the following procedure to call a modem that has callback security enabled.

NOTE

Enable autoanswer on the calling modem (S0=1 or S0=2).

1. Using a data communication program such as HyperTerminal, dial the callback modem’s number.

2. When the connection is established, the callback modem responds with a request for a password.

3. Type the modem’s password, then press Enter. You have three attempts to enter a valid password or be disconnected.

4. If the password is valid, the callback modem disconnects. Then, after a short delay, it calls the number associated with the password and establishes a working connection.

NOTE

If you are calling a direct connect number, you must append a hyphen (-) to the password. If the corresponding phone number has a hyphen as its first character, you will be able to go directly online with the callback modem. If the corresponding phone number has no hyphen character, you will be prompted for a different password.

7.5 Callback Security Commands

The following AT commands are used with callback security.

Command: #DBn Callback Enable/Disable Values: n = 0 or 1 Default: 0 Description: Enables or disables callback security. When callback security is enabled, phone

number memory locations 0–4, used for quick dialing and DTR dialing, become unavailable and are replaced by callback security memory locations 1–30. The phone number memory locations and their contents are restored when callback security is disabled.

#DB0 Disables callback security. #DB1 Enables callback security.

ENTER OFF? #1 ←, ENT

CALLBACK ON?

8. Troubleshooting

Your modem was thoroughly tested 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, the modem might be defective. However, it is more likely that the source of your problem lies elsewhere. Please read this chapter before calling Technical Support (Appendix B).

8.1 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, and the LCD should light. If the LEDs and LCD 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 transformer module is firmly connected to the modem and to the wall outlet or power strip.

• If the power strip is on and the modem switch is on, try moving the transformer module to another outlet on the power strip.

• Make sure the outlet is live by plugging another known working device, such as a lamp, into it.

• The modem or transformer module may be defective. If you have another Black Box modem, try swapping modems. If the problem goes away, the first modem or transformer module may be defective. Call Technical Support for assistance.

CAUTION

Do not under any circumstances replace the transformer module with one designed for another product; this can damage the modem.

8.2 The Modem Does Not Respond to Commands

• Make sure the modem is plugged in and turned on.

• Make sure you are issuing the modem commands from data communication software, either manually in terminal mode or automatically by configuring the software.

• 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 your communication software’s connection setup.

• Try resetting your modem by turning it off and on.

• 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 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.

• 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 Black Box modem, try swapping modems. If the problem goes away, call Technical Support.

8.3 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.

You can narrow the list of possibilities by using extended result codes. Extended result codes are enabled by default. If they have been disabled, type V1X4 in the modem’s initialization string, or in terminal mode type ATV1X4 and press Enter. When you dial again, the modem reports the call’s progress.

CHAPTER 8: Troubleshooting

V.92 DIALUP 2-WIRE OR 4-WIRE LEASED-LINE DATA/FAX MODEM USER’S GUIDE

• If the modem reports NO DIALTONE, make sure 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. 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 (for example, ATDT9). Note the comma, which inserts a pause before the number is dialed. By inserting 9, into the dial prefix, you don’t have to include it in each directory entry.

To change the dial prefix in Windows 95 HyperTerminal, select Connect from the Call, click Dialing Properties, and type 9 in the local and long-distance boxes in the How I dial from this location section.

• 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.

8.4 The Modem Disconnects While Online

• If you have Call Waiting on the same phone line as your modem, it can interrupt your connection when someone tries to call you. If you have Call Waiting, disable it before each call. In most telephone areas in Japan, you can disable Call Waiting by preceding the telephone number with **99#.

You can automatically disable Call Waiting by including the disabling code in the modem’s dial prefix (for example, ATDT*70). To change the dial prefix in Windows Terminal, select Settings|Modem Commands. To change it in 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.

CHAPTER 8: Troubleshooting

• If you were online, it 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.

8.5 The 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, &Q1, &Q5, or &Q6 is also set. For more information, see the &D command in the AT Commands Reference Guide on the CD shipped with your modem. For information on changing the modem’s default configuration, see Section 4.3 (for LCD options) or the AT Commands Reference Guide (for AT commands).

• Autoanswer might be disabled. Turn on autoanswer in your datacomm program or send the command ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.

8.6 File Transfer Is Slower Than It Should Be

• You might have an older UART. For best throughput, install a 16550AFN UART or an ISI serial port card.

• 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 ensure 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.

• Try typing in the &V1 command to display information about the last connection, making an LCD print of the connection statistics and checking for parameters that might be unacceptable.

8.7 Data Is Being Lost

• If you are using data compression and a high-speed serial port, set the serial port baud rate to four times the data rate.

• Your UART might not be reliable at serial port speeds over 9600 bps or 19,200 bps. Turn off data compression, reset your serial port speed to a lower rate, or replace your serial port with a faster one.

• 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.

• Try typing in the &V1 command to display information about the last connection, making an LCD print of the connection statistics and checking for parameters that might be unacceptable.

8.8 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.

V.92 DIALUP 2-WIRE OR 4-WIRE LEASED-LINE DATA/FAX MODEM USER’S GUIDE

• 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 typing in the &V1 command to display information about the last connection, making an LCD print of the connection statistics and checking for parameters that might be unacceptable.

8.9 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.

V.92 DIALUP 2-WIRE OR 4-WIRE LEASED-LINE DATA/FAX MODEM USER’S GUIDE

Appendix C. Upgrading the

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.

The upgrade procedure consists of the following steps.

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

a. Run your favorite terminal program. If you are using Windows, you can use HyperTerminal.

b. In the program’s terminal window, type AT&F. Even if you cannot see the AT&F command on your

LCD, be sure to type it completely, then press Enter. If the modem does not respond with OK, repeat the AT&F command.

c. Now type ATI3, press Enter, and record your results. The firmware version should appear first in the

response, which should look similar to the following:

ACF3_V1.702a_V90_P21_FSH

2. Identify the current version of the firmware by calling Tech Support. If your modem already has the current firmware, there is no need to update it.

WARNING

The new firmware’s first digit must match the old firmware’s first digit, or the modem may not work properly. For example, if your current firmware version is 4.16, replace it only with 4.xx firmware, not 6.xx firmware.

3. Download the upgrade file for your modem.

a. Obtain new firmware from Technical Support.

b. Download the upgrade file for your modem by clicking its name, and save the file in a temporary folder

on your hard disk.

c. 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.

4. Extract the firmware .HEX file and the appropriate flash upgrade program from the file you downloaded.

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

b. Extract the upgrade files by double-clicking the file name. The extracted files include a .HEX file (it

contains the upgrade data) and a Readme file.

c. Copy the upgrade .HEX file into the Flash Wizard folder.

APPENDIX C: Upgrading the Firmware

5. Document and 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&F command to the modem to clear the stored parameters.

a. Run your favorite terminal program. If you are using Windows 2000 or XP, you can use HyperTerminal.

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

c. Record your parameters by saving the LCDs and sending them to your printer.

d. Type AT&F and press Enter to clear your stored parameters and reset your modem to its factory default.

e. Close the terminal program.

6. Upgrade the modem’s firmware using the .HEX file and the flash upgrade program.

Before you begin the following procedure, read the README.TXT file extracted from the upgrade archive file. Note the file name for the boot code (for example, F35ALOAD.S37) and the file name for the new firmware (for example, BKQG300G.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 back for repair.

a. 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 devices connected to your system.

NOTE

If the message “ERROR—No valid devices detected” is displayed, verify that the modem is turned on and that all cables are correctly and securely attached.

b. Click the modem to be upgraded, then click Next.

c. Select the port to be upgraded from the Port list, select the appropriate .HEX file from the Hex File list, then click Next.

NOTE

Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.

d. The Progress dialog box appears. It features a status bar that indicates the upgrade’s progress.

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.

V.92 DIALUP 2-WIRE OR 4-WIRE LEASED-LINE DATA/FAX MODEM USER’S GUIDE

e. When the flash upgrade is complete, the message Programming Complete appears. Click Next to

continue.

f. The Results dialog box appears next. Click Finish to exit Flash Wizard.

7. Restore your parameters.

Open your terminal program to reprogram your modem parameters or to confirm the update by typing ATI3 in the terminal window and pressing Enter.

APPENDIX D: Installing a Modem Under Linux

Appendix D. Installing a Modem

Under Linux

This appendix explains how to install a modem on a computer operating 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.

To start, connect the external modem to an available serial port. Standard Linux serial-port definitions are shown below.

PC port Linux port

Com1 ttyS0 Com2 ttyS1 Com3 ttyS2 Com4 ttyS3

Next, you’ll need 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, type 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 LCD should display OK to verify the operation. Or, dial a phone number to verify line operation

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

7. On the help menu, type 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 ISP you are calling assigns you the DNS and 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 LCD, select the Gnome Footprint.
