This operation modifies a Termination Point Pool, i.e. add/remove TPs or GTPs to/from a TPPool.

Operation Exceptions:
1. NOT_IMPLEMENTED - Raised when EMS does not support modification of TPPools via this interface.
2. INTERNAL_ERROR - Raised in case of non-specific EMS internal failure.
3. UNABLE_TO_COMPLY - Raised in case one or more TPs or GTPs do not exist or do not belong to theTPPool's
    Subnetwork, and so the addressed TPPool object can not be modified.
4. INVALID_INPUT - Raised when input parameter is syntactically incorrect.
5. ENTITY_NOT_FOUND - Raised when the TPPool to be modified does not exist.
6. OBJECT_IN_USE - Raised when one or more of the TPs or GTPs to be removed are not idle, or one or more TPs or
    GTPs to be added are contained in a GTP or another TP pool.
7. CAPACITY_EXCEEDED - Raised when the operation would result in resources being created or activated beyond
    the capacity supported by the NE/EMS.
