R2511-HP MSR Router Series Layer 2 - WAN Command Reference(V5)

353
Parameters
incoming-access: Incoming access policy.
outgoing-access: Outgoing access policy.
suppress all: Suppresses all. If the incoming packet contains CUG facility, delete the CUG facility and
process the call. It does not apply to outgoing call.
suppress preferential: Processes only the calls configured with preference rule.
Usage guidelines
The command is used at DCE end. You can use the link-protocol x25 dce command to set the interface
to operate in DCE mode. 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-access parameter is selected, the system suppresses incoming calls. 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-access parameter is selected, the system suppresses outgoing calls. 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 selected, the system removes CUG facilities for the incoming calls
with CUG facilities and makes call processing. This parameter is ineffective on 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 on outgoing calls.
