Data Operation

Possible Display Problems

If the response from the remote end is unintelligible “garbage,” chances are that the speed or parity bit selection is incorrect. In this case, assuming that your terminal device allows, the parameters may be corrected without disconnecting the call. Otherwise, you must disconnect, correct the parameters, and then try the call again.

Disconnecting a Data Call

Most remote systems will have a command or menu selection for logging off. When you select the appropriate means, the remote system will disconnect or hang up. The PBX will disconnect the call and, after a moment, the 8400B Plus Data Module will send the following message to your display:

NO CARRIER

Alternatively, you can use the following disconnect procedure:

Selection: +++

OK

The prompt Selection: is simply a representation of how the remote system might ask you for your next command or menu selection. Type the escape sequence (default is +++) but do not press ENTER . (Pause before typing +++ , type +++ quickly, and then pause again after typing +++.) When the 8400B Plus Data Module responds with OK, type the command line:

ATH ENTER

The PBX will disconnect from the remote end device, and the 8400B Plus Data Module will send the OK message to the terminal display.
