Description: This object stores the location and plug-in type of 
all cards that were added to the UMC system when

the agent with 
umc1InventoryPluginTableChangeHistoryIndex sequence 
number. 

The byte-format structure of this object is as follows:
   octet[0] Version number of the octet representation. The 
            version number for the initial implementation will 
            be 0x01.
   
   For version number 0x01 the remaining octets will be defined 
   as follows :
   octet[1] Total number of records in the varbind, where each 
            record consists of a length octet(length of the record),
            a terminal identifier octet, a shelf identifier octet, 
            a slot identifier octet and two octets for saving 
            plug-in type.
   
   ---Record #1
   octet[2] Length of the first record.
   octet[3] Terminal Identifier of the first record.
   octet[4] Shelf identifier of the first record.
   octet[5] Slot identifier of the first record.
