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 ) b efore 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.
