User Guide 78
5 Remote Configuration Introduction Remote configuration is a network management tool that allows you to configure modems anywhere in your network from one location. With password-protected remote configuration, you can issue AT commands to a remote MT5634ZBA or MT5634ZBAV 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. 1.
User Guide Setup Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who has an owner’s manual knows the default setup password, for security you should change the password and possibly also the remote configuration escape character. Changing the Setup Password 1. Open a data communications program such as HyperTerminal. 2. In the terminal window, type AT#SMTSMODEM (or AT#Syyyyyy if you have replaced the MTSMODEM password with yyyyyy) and press ENTER.
5 Remote Configuration Changing the Remote Escape Character To increase security, you can change a remote modem’s remote configuration escape character. 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—but if you do this remotely, you won’t be able to change it back remotely! 1.

User Guide 84
6 Callback Security Introduction 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.
User Guide To Change the Setup Password 1. Open a data communications program such as HyperTerminal. 2. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the MTSMODEM password with xxxxxxxx) and press ENTER. The modem responds with OK if the setup password is correct, and ERROR if it is wrong. 3. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and press ENTER.
6 Callback Security • To turn off callback security, type AT#CBS0 and press ENTER. Callers no longer need a password to connect to the modem, the modem is unable to call them back, and the stored dialing command locations 0–3 become available. • To turn on both local and remote callback security, type AT#CBS1 and press ENTER. With local security turned on, you must enter the setup password before you can enter any AT command except the AT, ATIn, and AT#Sxxxxxxxx commands.
User Guide 2. In the terminal window, type AT#Sxxxxxxxx, where xxxxxxxx is your password, and press ENTER. The modem responds with OK if the setup password is correct, and ERROR if it is wrong. 3. The default parity value for your modem is no parity (AT#CBP0). To change the modem’s prompt messages to use even parity, typeAT#CBP2 and press ENTER. For odd parity, type AT#CBP1 and press ENTER. 4. To store the new parity value, type AT&W and press ENTER. To Assign Callback Passwords and Phone Numbers 1.
6 Callback Security string, and press ENTER. The phone number must be preceded by DT, for tone dialing, or DP, 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. Add if you want a mobile caller to be able to enter his current phone number for callback. - Direct connection.
User Guide Calling Procedures Use the following procedures to call a modem that has callback security enabled. Note: Autoanswer must be enabled on the calling modem ( S0=1). Password-Only Callback Use this procedure when calling from a fixed location. 1. Using a data communications program such as HyperTerminal, dial the number of the callback modem. 2. When the connection is established, the callback modem responds with the following message: Password> 3.
6 Callback Security 7. Type the same password that you used to initiate the call. You have three attempts to enter the password or be disconnected. 8. If the password is valid, the following message appears and the modems establish a working connection: OK Connecting Number-Entry Callback Mobile callers should use this procedure when calling from a phone number different from that stored with the password. The password that is used must be set up for optional number-entry callback. 1.
User Guide callback modem is unable to establish a connection, it tries again, up to the number of attempts specified by the #CBAn command. 6. After the modems reconnect, the following message reappears: Password> 7. Type the same password that you used to initiate the call. You have three attempts to enter the password or be disconnected. 8.
6 Callback Security 5. After the delay specified by the #CBDn command, the callback modem calls the extension that you entered after the + character. If the callback modem is unable to establish a connection, it tries again, up to the number of attempts specified by the #CBAn command. 6. After the modems reconnect, the following message reappears: Password> 7. Type the same password that you used to initiate the call. You have three attempts to enter the password or be disconnected. 8.
User Guide Callback Security Commands The following AT commands are used with callback security. Most can be entered only after the setup password has been entered. Command: #CBAn Values: Default: Description: Callback Attempts n = 1–255 4 Sets the number of callback attempts that are allowed after passwords have been exchanged between modems.·This command can be entered after the setup password has been entered and callback security is enabled.
6 Callback Security Command: #CBFR Callback Failed Attempts Reset Values: n/a Default: n/a Description: Resets the number of failed callback password attempts to 0. It does not reset the number stored in nonvolatile memory. This command can be entered after the setup password has been entered and callback security is enabled.
User Guide Command: #CBPn Values: Default: Description: Callback Parity n = 0, 1, or 2 0 Sets parity for the callback security messages. The parity of the messages should match the parity of the computer the modem is attached to. This command can be entered after the setup password has been entered and callback security is enabled. #CBP0 No parity. #CBP1 Odd parity. #CBP2 Even parity.
6 Callback Security #CBS0 Disables callback security. With this command, the modem connects as if it did not have callback security. This command can be entered after the setup password has been entered. #CBS1 Enables local and remote callback security. Local callback security requires that the setup password be entered to use the AT command set. The only AT commands that are available without the setup password are AT, ATI, and AT#Sx. For the remote callback security description, see the #CBS2 description.
User Guide Command: #Sx Values: Default: Description: Enter Setup Password x= password (1–8 characters, case sensitive) MTSMODEM Enters the password used for callback security and remote configuration setup. This command allows the use of all callback security commands. Command: #S=x Values: Default: Description: Store Setup Password x= password (1–8 characters, case sensitive) MTSMODEM Stores a new password for callback security and remote configuration setup.
6 Callback Security only after the setup password has been entered and callback security is enabled. Options: + - ,??? Enables the caller to enter a new callback number during password entry. The + character must be the first or second character in the command string. Enables the caller to choose a direct connection (no callback) during password entry. The character must be the first or second character in the command string. Enables the caller to enter an extension number during password entry.

User Guide 102
7 Solving Problems Introduction 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.
User Guide 4 4 4 4 4 If the power supply 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 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 modem power supply to another outlet on the power strip. Test that the outlet is live by plugging a lamp into it. The modem or power supply may be defective.
7 Solving Problems 4 4 4 4 4 4 Try resetting your modem by turning it off and on. If you are using DOS or Windows 3.1 communications software, make sure the initialization string includes &F as the first command, to cancel any “leftover’ command that could affect the modem’s operation. If you don’t get an OK, the problem may still be in the communications software. Make sure you have done whatever is necessary in your software to make a port connection.
User Guide To look for address or IRQ conflicts if you use Windows 3.1x, select File | Run in Program Manager, type MSD, and press ENTER. Then select Mouse, COM Ports, and IRQ Status and note the addresses and IRQs that are in use. If you find an IRQ conflict, note which IRQs are not being used, then change one of the conflicting devices to use one of the unused IRQs. If you find an address conflict, change the address of one of the conflicting devices. To change a port address or IRQ in Windows 3.
7 Solving Problems The Modem Dials But Cannot Connect There can be several reasons the ZBA 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.
User Guide 4 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.
7 Solving Problems The Modem Disconnects While Online 4 4 4 4 4 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 North America, you can disable Call Waiting by preceding the telephone number with *70 (check with your local telephone company).
User Guide The Modem Cannot Connect When Answering 4 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. File Transfer Is Slower Than It Should Be 4 4 4 4 4 4 You might have an older UART. For best throughput, install a 16550AFN UART or a Multi-Tech ISI serial port card. See the “Quick Start” chapter for information on how to identify your UART. If you are running under Windows 3.
7 Solving Problems Data Is Being Lost 4 4 4 4 4 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.
User Guide 4 connecting at a slower speed or disabling error correction. (With no error correction, however, line noise can cause garbage characters.) Try entering the I11 ommand in online mode to display diagnostic information, making a screen print of the diagnostics listing, and checking for parameters that might be unacceptable (number of retrains, round trip delay, etc.).

C Loopback Tests Appendix C: Loopback Tests Introduction Each time you turn on your modem, it performs an automatic self-test to ensure proper operation. Your modem also has three diagnostic tests: local analog loopback, remote digital loopback, and local digital loopback. These ITU-T V.54 loopback tests isolate telephone circuit and transmission problems. In a loopback test, data from your computer loops through the circuits of your modem and/or a remote modem before it appears on your monitor.
User Guide Local Analog Loopback Test (V.54 Loop 3) In this test, data from your computer or terminal is sent to your modem’s transmitter, converted into analog form, looped back to the modem’s receiver, converted into digital form, and then sent to your monitor for verification. No connection to the phone line is required. AT&T1 CONNECT UUUUUUUUU UUU Digital Computer or Terminal Analog Local MultiModem Figure C-1. Local analog loopback test. Test procedure 1. Connect the modem to your computer.
C Loopback Tests displayed on your monitor. The TD and RD LEDs should flash when a character is entered. 5. To exit the test, type the escape sequence +++AT and press ENTER. This puts the modem in online command mode. Then type either AT&T or ATH to return to command mode. 6. Your modem passes this test if the data received on your monitor are the same as the data entered from your keyboard.
User Guide Test procedure 1. Arrange to have &T6 set on the remote test modem. 2. Open your communications software and go into terminal mode. Type AT and press ENTER; you should get an OK message. Type AT\N and press ENTER to disable error correction. 3. Dial the remote modem and establish your online connection. 4. Type the escape sequence +++AT and press ENTER to bring your modem into online command mode. 5. Type AT&T6 and press ENTER.
C Loopback Tests Local Digital Loopback Test (V.54 Loop 2) The local digital loopback test is identical to the remote digital loopback test with one exception. Instead of using your modem to signal a remote modem to place itself in digital loopback mode, your modem is placed in digital loopback mode while the remote modem is not. Data is entered and transmitted from the remote modem, sent across the phone line to your modem, and looped back to the remote modem.
User Guide 5. Have someone enter data from the remote keyboard. For this test, typing multiple uppercase U characters is a good way to send an alternating test pattern of binary ones and zeros. The data received by your modem enters its analog receiver, is converted to digital data, is reconverted into analog, and then is transmitted back to the remote modem. Your modem passes this test if the data received on the remote monitor is the same as the data entered from the remote keyboard. 6.
