Summary: 
This paper proposes a universal structure for STM-N(N=1, 2, 3, ) multiplex line terminals that only utilizes N chips CMOS LSIs for Section OverHead (SOH) processing. The uniquely configured LSIs are applicable to any STM-N line terminal equipment. Reasonable frame alignment performance attributes, such as the maximum average reframe time, false in-frame time, out-of-frame detection time, and misframe time, are calculated for the configuration. A prototype SOH processing LSI built on 0.8m BiCMOS technology successfully realizes the functions needed for multiplex section termination. The STM-64 frame is also demonstrated using the proposed circuit configuration and prototype LSIs.
