ODUk SNCP protection of the SNC/S type


ODUk SNCP (SNC/S) protects services against defects detected at the ODUkT sub-layer trail (TCM). Switching is triggered only on a defect in the protected domain. That is, a defect at the connected ODUk layer does not trigger switching. Some portion of the original trail's capacity is over-written such that the part of the connection that is of interest can be directly monitored by a trail created at a sublayer.
