OTN – Lesson 7 – Converting OTL4.4 Signals back into a Composite OTU4 Signal – Video 1 of 3
This blog post contains the first (of 3) videos that describes how we take an OTL4.4 Interface (or set of signals) and converts these signals back into a single (composite) OTU4 signal.
This video introduces the OTSiG/OTUk_A_Sk Atomic Function (a fancy word for OTL4.4 Sink Terminal).
This video discusses how the OTSiG/OTUk_A_Sk Function accepts electrical lane signals from an Optical Module (in the OTL4.4 format) and processes these signals by:
- Checking to see if we should declare/clear the dLOS-P (Loss of Signal – Path) Defect condition with these Electrical Lane signals, and
- De-Multiplexing these signals into the 20 Logical Lane signal.
