Transfer Mode (ATM) Trunking

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.
Codeset to Send Display
This field defines the codeset for sending the information element for display. The value depends on the
type of server/switch to which the user is connected.
