This operation is used to retrieve the "current" CTPs that are contained within a specific TP (PTP or CTP), at specific layer rates. A "current" CTP is defined as a CTP that is either cross-connectible or cross-connected, in the current mapping configuration.
Examples for contained Current 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.
