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
