Does anyone know of any publicly available documents which describe the properties of the referenced proprietary solutions? If so, would you please provide pointers.
Am I correct in thinking that this is what is called "Transparency" in draft-ietf-ccamp-gmpls-sonet-sdh-01.txt?
Can you point to any further material beyond appendix 5 of the draft which explains for what transparency is used and what types of transparency are required for what applications?
