Carrier Medium
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
isdn and, on the
System-Parameters Customer-Options screen, either the Async. Transfer Mode
(ATM) Trunking or H.323 field is
y.
Charge Advice
Use this field to accumulate and access charge information about a call. You
already must have set the CDR Reports field to
y or r (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.
