cwn Atm Source PRS Reference

1.3.6.1.4.1.9.9.223.1.4.1.1.4

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. The object takes the value 'internal' when the PRS for this source is an onboard oscillator local to the device. For any other cases the value 'external' is used. If the value of this object is used as a tiebreaker by the 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.
