- Abstract
- The optical supervisory channel (VSC) in WDM (Wavelength Division Multiplexing) transmission systems is used for VAM (Operations, Administrations and Management) function like overhead information in SDH (Synchronous Digital Hierarchy). We present supervisory information contents and alarm propagation procedure in our 1.6T WDM transmission system. Also, tbis paper describes the OSC frame structure and the OSC subsystem configuration that can provide reliable and etlective operation and maintenance capability.
