ISDN Trunk Traffic Intensity

Traffic intensity carried by the ISDN trunk group is calculated in the same way of analog trunk
group except the holding time calculation.

All Trunk Traffic Intensity

Traffic intensity reported is calculated with the holding time of all trunks.

Abandoned Calls

An abandoned call is usually an incoming trunk call that the caller hangs up before it is answered.
Incoming calls on a Strata Net trunk are never counted as abandoned. When a call from Node A to
Node B via Strata Net is attempted, Node B will count the attempt as an incoming trunk call. If the
call is abandoned it will not be included in the abandoned call count.
A call on an incoming CO line to Node A, routed to a station in Node B, that is abandoned will be
recorded as an abandoned call only in Node A.
