430CHAPTER 26: LAPB AND X.25 CONFIGURATION COMMANDS

Note that if no logical channel identifier is specified, the information about all virtual circuits is displayed.

There are three types of virtual circuits as follows:

■An SVC (switched virtual circuit) is set up temporarily by X.25 through calling as required.

■A PVC is configured manually and exists regardless of the data transmission requirement.

■When the device works in X.25 switching mode, virtual circuits will be set up in order to transfer data.

Information about the three types of virtual circuits can be shown with this command, and only some fields of their outputs differ.
