ISDN trunk group 

This field lets you to specify the type of transport medium interface used for the 
ISDN trunk group. Appears only when the Group Type field is 

 and, on the 

System-Parameters Customer-Options screen, either the Async. Transfer Mode 
(ATM) Trunking or H.323 field is 

.

Use this field to accumulate and access charge information about a call. You 
already must have set the CDR Reports field to 

 or 

 (ring-intvl) before changing 

this field from its default of none. Remember that receiving Advice of Charge 
during the call (administered as “automatic” or “during-on-request”) affects 
system performance because of the increased ISDN message activity on the 
signaling channel, which may reduce the maximum call capacity.
