OTN – Lesson 9 – Video 11 – OTU Layer Defect Handling Requirements and Scenarios

In this video, we presume that some OTUk-Layer circuitry is declaring a certain defect condition. We then determine how OTU (and in some cases) ODU-layer circuitry is expected to respond.

OTN – Lesson 9 – Video 11 – OTU Layer Defect Scenarios

This blog post presents a video that discusses the various defects that OTN equipment can declare at the OTU Layer. Additionally, this video will describe how OTU Layer circuitry should respond to and handle these defect conditions.

This video will state whether OTU Layer circuitry should:

Transmit the SM-BDI Indicator upstream, or
Transmit the ODU-AIS Maintenance Signal downstream,
Increment Certain Performance Monitoring parameters, or
Halt Incrementing Certain Performance Monitoring parameters.

In response to each type of defect that OTU Layer circuitry can declare.

This video covers both Single-Lane (e.g., OTSi/OTUk_A_Sk) and Multi-Lane (e.g., OTSiG/OTUk_A_Sk) applications.
