4.7 Path Overhead (RPOH, TPOH)

The Path Overhead Processor is responsible for pointer interpretation, path overhead processing,
synchronous payload envelope, path level alarm and performance monitoring on both receive and
transmit sides. The Path Overhead section configures and monitors the path overhead on both
receive and transmit sides. Write access is given to the path trace message (J1) and the path signal
label (C2) and other overhead bytes. For diagnostic purposes, errors can be introduced in the path
overhead bytes. Additional functions are provided to automatically insert path AIS, force
generation of outgoing justification events.
