444CHAPTER 26: LAPB AND X.25 CONFIGURATION COMMANDS

Description Use the x25 cug-servicecommand to enable CUG service and suppression policies.

Use the undo x25 cug-servicecommand to disable CUG service.

By default, CUG service is disabled.

After CUG service is enabled, the system suppresses those calls matching the preset conditions. The details are:

■If no parameter is configured, allow incoming/outgoing calls without CUG facilities, and allow incoming/outgoing calls with CUG facilities after deleting the CUG facilities.

■If the incoming-accessparameter is chosen, the system suppresses incoming calls. That is, it suppresses the incoming calls that has CUG facilities but has no CUG mapping rules allowing them to pass, and lets the incoming calls without CUG facilities pass through.

■If the outgoing-accessparameter is chosen, the system suppresses outgoing calls. That is, it suppresses the outgoing calls that has CUG facilities but has no CUG mapping rules allowing them to pass, and lets the outgoing calls without CUG facilities pass through.

■If the suppress all parameter is chosen, the system removes CUG facilities for the incoming calls with CUG facilities and makes call processing. This parameter is ineffective to outgoing calls.

■When the suppress preferential parameter is included, if an incoming call with CUG facilities and the suppression rule is preferential, the system then removes its CUG facilities and make call processing. If the suppression rule is not preferential, the system does not remove its CUG facilities but lets it pass through. This parameter is ineffective to outgoing calls.
