Parent object index, could be
   - line index
   - port index

This object will indicate the index of the immediate
higher level object (line or port) of configChangeObjectIndex.
This object is applicable only when configChangeObjectIndex 
represents a channel, port, egress Q or resource partition
index.

Following specifies the mapping between the 
configChangeObjectIndex and its corresponding
configChangeParentObjectIndex.

configChangeObjectIndex         configChangeParentObjectIndex
-----------------------         -----------------------------
Port Index                      Line Index
Egress Q Index                  Port Index
Resource Partition Index        Port Index
Channel Index                   Port Index

When the 'Port Configuration Change' bit is set,
the configChangeParentObjectIndex will represent
a 'Line Index' which in turn has the following
special meaning in FRSM-2CT3 cards.

- configChangeParentObjectIndex range between 1..56
  indicates that the configuration change refers to the DS1 line
  index. A value of (128 + n) refers to DS3 line index 
  numbered 'n'.

This object object is applicable only in traps.
