Abstract:
1. A synchronous optical network (SONET) multiplexer module, comprising: a SONET multiplexer circuit, mounted on a supporting surface; and a face plate, coupled to the supporting surface, and having plural electrical connectors mounted thereto which are electrically coupled to the SONET multiplexer circuit and provide ports for synchronous transport signals (STSs) comprising multiples m of DS wherein the SONET multiplexer circuit comprises an optical interface, to receive an optical signal via said optical connector and convert it into an electrical signal, a SONET overhead terminator configured to locate SONET frames in said electrical signal received from said optical interface and extract selected overhead bytes in said SONET frames, a mapper operable to use data from said electrical signal received from said optical interface and said selected overhead bytes to generate a plurality of DS wherein said SONET multiplexer module is deployed as a single card dimensioned for deployment in a single card slot in a shelf of a telecommunications equipment bay having said face plate facing away from the shelf to allow said plural electrical connectors and said optical connector to be accessible outside of the shelf.
