I just buy multitech modem, MT9234ZBA for remote connection to my cisco router and juniper ns5gt's console. Unfortunately, I can not make it work. I configured it with ATS0 : to answer at the first ring. AT&W to save the setting. I don't know what are the parameters to be setup. could you please guide me ? I have the multitech diagram, but I can not update to you.

Hi,

For your requirement here is the remote configuration below.

Establish a data connection with a remote Multi Modem product.

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.

You can now send AT commands to configure the remote modem. When you have finished configuring the remote modem, save the new configuration by typing AT&W0, and pressing Enter.

Type ATO and press Enter to exit remote configuration. You can then break the connection in the normal way.

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.

To change the password Open a data communications program such as Phone Tools or HyperTerminal.

To change the password, type AT#S=your new password ENTER. The password can include any keyboard character, and must be one to eight characters long.

The modem responds with OK.

The new password is saved automatically. You can now either enter more AT commands or exit the data communications program. The next time you remotely configure the modem you must use the new setup password.

.

Changing the Remote Escape Character

Establish a remote configuration link with the remote modem as described in "Basic Procedure."

Type ATS9=n, where n is the ASCII code for the new remote configuration escape character, then press ENTER.

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

Type ATO to exit from remote configuration.

You can establish a high-speed connection to an external router, DSL modem, or cable modem, and provide firewall and general security for your network. Connect the provided Ethernet cable from the untrusted interface on the NetScreen-5GT device to the external router or modem. You have to use RJ 45 connector to connect them.

To establish a console session:

Plug the female DB-9 end of the serial cable into the serial port of your PC. (Be sure that the DB-9 is seated properly in the port.)

Plug the male DB-9 end of the serial cable into the Console port of theNetScreen-5GT device. (Be sure that the DB- is seated properly in the port.)

Launch a serial terminal program. (A commonly-used terminal program is Hargreaves HyperTerminal.) Typical settings to launch a console session with your NetScreen-5GT device are as follows:

• Baud Rate to 9600

• Parity to No

• Data Bits to 8

• Stop Bit to 1

• Flow Control to none

At the login prompt, type the default login name: netscreen.

At the password prompt, type the default password: netscreen.

Change the password, set an IP address. You will find detail configuration of ns5gt in its manual.
