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.
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.
Changing the Remote Escape Character To increase security, you can change a remote modem’s remote config- uration 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 (%).
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 re- ceived, 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#S xxxxxxxx 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.
• 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 com- mand locations 0–3 become available. •...
User Guide 2. In the terminal window, type AT#S xxxxxxxx , 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.

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.
User Guide 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 mo- dem 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.
Try resetting your modem by turning it off and on. If you are using DOS or Windows 3.1 communications software, make sure the ini- tialization 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 communica- tions software.

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.
The Modem Dials But Cannot Connect There can be several reasons the ZBA fails to make a connection. Pos- sibilities include • lack of a physical connection to the telephone line. • a wrong dial tone. • a busy signal. •...
Page 118
User Guide 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.
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 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 Autoanswer might be disabled. Turn on autoanswer in your data- comm 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 You might have an older UART.
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.
User Guide 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 re- trains, 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.
User Guide Local Analog Loopback Test (V.54 Loop 3) In this test, data from your computer or terminal is sent to your mo- dem’s transmitter, converted into analog form, looped back to the mo- dem’s receiver, converted into digital form, and then sent to your monitor for verification.

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.
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 re- mote modem to place itself in digital loopback mode, your modem is placed in digital loopback mode while the remote modem is not.

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.
