Deactivate and delete a Subnetwork Connection.
This operation also applies to bundled SNCs.

Operation Exceptions:
1. INTERNAL_ERROR - Raised in case of non-specific EMS internal failure.
2. INVALID_INPUT - Raised when any input parameter is syntactically incorrect (e.g. sncName does not refer to an SNC
    object, or any field in tpsToModify is invalid).
3. ENTITY_NOT_FOUND - Raised when sncName or tpsToModify reference an object that does not exist.
4. UNABLE_TO_COMPLY - Raised when the SNC is fixed and can not be deactivated.
    Raised when the EMS is unable to execute the request because at least one of the parameters although valid can
    not be set and that parameter is identified as "not best effort" in the supporting document LayeredParameters.pdf
    associated to the TransmissionParameters object (such that the TPs will be left in an invalid state after the deactivate
    operation); i.e. the whole operation will be rejected if one parameter fails that must be set.
5. NE_COMM_LOSS - Raised when communication to managed element is lost and this prevents the deactivation of the SNC.
