Optical path signal termination equipment |
摘要 |
In optical path signal termination equipment which converts between an SDH signal transmitted at the electrical level and an optical path signal transmitted at the optical level, an optical path supervisory signal is inserted in the optical path signal without increasing the signal length. This is accomplished by utilizing the SDH section supervisory signal area contained in the SDH signal as the area for the optical path supervisory signal in the optical path signal.
