Terminates and maps the CTP such that it will be able to support connections at lower (client) rates (actually, such that the CTP's contained (client) CTPs can be used for connections at their native (lower) rates).  E.g., for an STS1 CTP, successfully terminating and mapping the CTP will allow for support of lower rate connections such as VT1.5 connections.
If the CTP is already terminated and mapped, the operation will succeed.

Operation Exceptions:
1. NOT_IMPLEMENTED - Raised when CTP does not support termination and mapping.
2. INTERNAL_ERROR - Raised in case of non-specific EMS internal failure.
3. UNABLE_TO_COMPLY - Raised when CTP is involved in an existing, active cross connection at the CTP's
    native rate (CTP's layerRate) (i.e., the CTP's "connectionState" attribute value is something other than
    "NOT_CONNECTED"; the CTP is not in a valid state).
4. NE_COMM_LOSS - Raised when EMS is unable to communicate with NE.
