This table contains entries for active calls in the
system which utilize modem resources.
          
It contains general modem session attributes and
statistics at the modem link and modem protocol layers.
          
The table extends the cctActiveTable, using the same
index, cctActiveCallId.
          
There are no entries for calls not requiring modem
services.
cctmActiveEntry entry .1.3.6.1.4.1.9.9.165.1.1.1.1
The information regarding a single call.

Entries are created and deleted in sync with the entries
in cctActiveTable, if the call utilizes modem service.

terminated modem calls.
          
It contains low level modem session attributes and
statistics at the modem link and modem protocol layers.
          
The table extends the cctHistoryTable, using the same
