A collection of statistics for conversations between particular ATM endpoint addresses that have been discovered on behalf of the portSelectGroup associated with this entry. The probe will add a new entry to this table for all conversations (connections) between distinct source and destination address pairs, detected in all calls, on all ports configured in the portSelGrpEntry controlling this collection. Further, this table will only contain entries that have a corresponding entry in the atmMatrixDSTable with the same source address and destination address.
