   179 // that can be modified should have a visibility that is to that node's

   180 // level and not further (i.e. changes here will affect this connection

   181 // only, not every connection that uses this MCPR)

   182 //      MCPR - AccessPointConfig() contains information that is used by

   183 //             all connections under that MCPR and is unchanging

   184 //       CPR - Again for all connections under that CPR and is unchanging

   185 //      SCPR - Connection specific information (i.e. can change and does change)

   186 //        DC - No point - just reads information.

   187 // Here we've moved basically all of the configuration information that was in

   188 // the MCPR [that could be moved] this is because some of it changes / is overwritten

   189 // with information that comes out of etel/modem.  This also has the added benefit of

   190 // freeing up memory in cases where the connection is torn down but the MCPR lies 

   191 // around for availability purposes.  In the future, this code (or something like it)

   192 // should be moved into the PDP.CPR when it exists.
