Configuration and Operation

Data Operation

This section provides information on how to use the 8400B Plus Data Module for data calls.

From Data Mode to Command Mode and Back

An escape sequence, +++ , can be typed at any time during a data call to return temporarily to command mode. Your call does not disconnect, but data is not exchanged. Once you have “escaped” to command mode, the 8400B Plus Data Module returns OK to acknowledge that it has entered command mode (see ‘‘Command Acknowledgment’’ on page 3-4).

At this point, you can issue commands to the 8400B Plus Data Module. As long as the data call has not been disconnected, you can use the ATO command to return to data mode.

One other condition will cause the 8400B Plus Data Module to switch from data mode to command mode. If the PBX senses that the remote device has disconnected, it will disconnect the call to the 8400B Plus Data Module. The 8400B Plus Data Module will turn off the green LED, turn on the red LED if it is not already on, display a result code message on your terminal screen (such as NO CARRIER), and then return to command mode.

The escape sequence and all other commands discussed in this section are explained in Appendix A.

Dialing a Data Call

The dial command is issued to the 8400B Plus Data Module in the form ATDTnnn...n, where D is the dial command, T is the dial modifier (see Appendix B for more information on dial modifiers), and nnn...n represents the number you wish to dial. The command line can hold up to 40 characters, so you can usually precede the D with other commands on the same line.
