Chapter 6 – Callback Security

5.After the delay specified by the #CBDn command, the callback modem calls the number associated with the password. 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 are allowed three attempts to enter the password, after which you will 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.Using a data communications program such as HyperTerminal or PhoneTools, dial the number of the callback modem.

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

Password>

3.Type a number-entry password, press the plus key (+), type ATDT and the number to call back to, and press ENTER. You have three attempts or one minute to enter a valid password.

Note: When you type your phone number, be sure to include the long distance and area codes if they are needed.

4.If the password is valid, the following message appears, and the modems disconnect:

OK Disconnecting

5.After the delay specified by the #CBDn command, the callback modem calls the number 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 are allowed three attempts to enter the password, after which you will be disconnected.

8.If the password is valid, the following message appears and the modems establish a working connection:

OK Connecting

Extension-Entry Callback

Use this procedure when calling from an extension at the callback number. The password that you use must be set up for an optional extension-entry callback.

1.Using a data communications program such as HyperTerminal or PhoneTools, dial the number of the callback modem.

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

Password>

3.Type an extension-entry password, press the plus key (+), type the extension to call back to, and press ENTER. You have three attempts or one minute to enter a valid password.

4.If the password is valid, the following message appears, and the modems disconnect:

OK Disconnecting

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 you used to initiate the call. You are allowed three attempts to enter the password. After that, you will be disconnected.

8.If the password is valid, the following message appears, and the modems establish a working connection:
