cncNcdpPRSReference

An value that identifies the primary reference source that
the network clock available from this source is traceable 
to if configured as a source of network clock for NCDP.
(See American National Standards Institute, ANSI T1.101,
'Synchronization Interface for Digital Networks' and Bell 
Communications Research, GR-436-CORE, 'Digital Network 
Synchronization Plan' for more        detailed information 
regarding Primary Reference Sources.).  If a source of 
network clock is an onboard oscillator local to the device
it is 'internal' otherwise it is 'external'.  If the value
of this object is used as a tiebreaker by the NCDP
algorithm,'external' wins over 'internal'.
              
All 'external' sources of network clock are assumed to be
traceable to the same PRS by the NCDP protocol entity.
