A PTP (PhysicalTerminationPoint) is an actual or potential end point of a topological (physical) link. Basically a representation of a physical port, e.g., a T3 port, an OC-N optical port, etc. PTP does not have attributes beyond those inherited from the TP superclass.	PTP does participate in associations unique to the PTP class (i.e., associations which do not apply to CTPs and therefore cannot be captured via the TP superclass).PTP does issue object creation and object deletion notifications (in contrast to TP and CTP classes).

MTOSI Specific Documentation
This class is applicable to MTOSI. The specific operations and relationships that apply to MTOSI are listed in SD2-11. 
For MTOSI, references to "NMS" can be interpreted as "Requesting OS" and references to "EMS" can be interpreted as "Target OS", i.e., the OS that fulfills requests from another OS. 
The statements concerning Object Lifecycle, i.e., whether the object can be created by the NMS or EMS, are not particularly meaningful for MTOSI, since MTOSI does not define management systems with fixed roles such as the NMS and EMS entities in MTNM.

Object Lifecycle: Created and deleted by EMS. Containing ManagedElement object instance must exist before creation of PTP object instance.
