This operation is used to retrieve the names of the "potential" CTPs that are contained within a specific TP (PTP or CTP), at specific layer rates. Potential CTPs are all CTPs supported by all possible mapping configurations. If the layerRateList is empty then contained CTPs at all flexible and/or static LayerRates are returned.
Examples for contained Potential TPs in different states of usage are contained in the associated supporting document ContainedTPs.

Operation Exceptions:
1. INTERNAL_ERROR - Raised in case of non-specific EMS internal failure.
2.INVALID_INPUT - Raised when layerRateList contains undefined rates.
3. NE_COMM_LOSS - Raised when communication to managed element is lost.
