5.24.1.1.5. CND (Calling Name Delivery) 
If a name server is connected to a switch the calling name information
can be received in a delayed FACILITY message instead of the SETUP message.
The delayed information is then shown on the user display.
The calling name delivery feature can be disabled by adding the COT
BKNA to the trunk.
Traffic metering is expanded with three system wide peg counters:
- Calling name informations in SETUP message.
- Calling name informations in delayed FACILTY message.
- Calling name informations not available.
This feature is only supported with NI-2 or CorNet-NQ.
