Abstract
This paper discusses some functional requirements of a SONET (Synchronous Optical NETwork) 1 framer chip when used in an application for a 13-ISDN User Network Interface (UM), particularly the necessary physical layer Operations and Maintenance (O&M) capabilities which provide a basis for higher layer operations and maintenance functions. O&M functions include performance monitoring, failure state indications, and maintenance signals. This work is related to a SONET framer chip research prototype project at Bellcore, and the O&M functions described in this paper will be implemented in the framer chip.
