This operation is used to retrieve 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.
Note that in any case, this operation returns the complete object information for all contained CTPs, not just those CTPs that are directly contained by the TP.

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.
