OTN Lesson 4 – Mapping a Non-OTN Client Signal into an OPU Frame using the Generic Mapping Procedure (GMP)
This post includes a video that describes the GMP (Generic Mapping) Procedure – for mapping a Non-OTN client signal into an OTN signal (OPU frame).
This video also describes how we use the various JC (Justification Control) fields within the OPU overhead to manage the mapping of Non-OTN client data into an OPU frame.
Additionally, this video describes how we use these overhead fields to manage the de-mapping of this Non-OTN client data from an OPU frame.
NOTE: The roles of the JC fields are very different for GMP than for AMP and BMP.
