Usage guidelines
If the command is used at DCE side, use the link-protocol x25 dce command to set the interface as DCE.
CUG map is the exchange relationship between local (DTE device) and network (X.25 network) CUG
numbers when the device is processing CUG calls. For example, if the DTE with CUG number as 10
wants to call the DTE with CUG number as 20 in the network, the device will first find the map in the map
table. If the map is found, change the CUG number of the calling packet to 20 and forward the packet.
If not found, refuse to forward the packet.
You can specify the suppress rule when you configure CUG map. The following suppress rules are
available:
• Suppress income access no-incoming
• Suppress outgoing access no-outgoing
• Specify the preference rule preferential
Specifying as the preference rule depends on the CUG suppression policy. If the suppression policy is
configured as only suppressing the CUG of preference mapping, the system removes the CUG facilities
in the incoming call packet of this mapping and makes call processing.
