    摘要： A method of enabling transmission of a time-critical control signal event in a sync frame period, such as a pause signal that is generated when the receive buffer of an Ethernet switch is filled with packets beyond a threshold due to congestion of uplink asynchronous data, is disclosed. To transmit time-critical information in a synchronous Ethernet system, a current transmission period is checked upon detection of a time-critical event. If the current transmission period is a sync frame period, time-critical control information is generated, inserted into the first sub-sync frame after the time-critical event, and transmitted. If the current transmission period is an async frame period, a control frame including the time-critical control information is generated and transmitted.

    摘要： A communication/broadcast multiplexer and demultiplexer for multiplexing and demultiplexing communication and broadcast signals using a specific transmission standard in an optical network system that integrates broadcast and communication services using a channel selection technique. The multiplexer comprises a broadcast data input unit, a communication data input unit, and a synchronous Ethernet framer. The broadcast data input unit receives broadcast data switched on a subscriber basis through a broadcast switch in an optical line terminal (OLT) in the system, and transfers it as a synchronous data frame to the synchronous Ethernet framer. The communication data input unit receives communication data on a subscriber basis through an Ethernet switch in the OLT and transfers it as an asynchronous data frame to the synchronous Ethernet framer. The synchronous Ethernet framer converts both the received synchronous and asynchronous data frames into a TDM synchronous Ethernet frame, and outputs the TDM synchronous Ethernet frame.

    摘要： A photoelectric cross-connect system for an optical-communication system minimizes service recovery time when an error is generated. A plurality of nodes are connected by an optical-transmission line wherein each nodes automatically recognizes a data rate of an input signal and communicates over a redundant channel with an adjacent node when there is a certain type of error. An optical-receiving unit receives an optical signal performs O/E conversion. A main optical-transmitting unit recovers clock and data signals according to the converted signal and sets a data rate according to the converted signal for subsequent transmission; a redundant optical-transmitting unit recovers a clock and data according to the converted signal and sets a data rate according to the converted signal for subsequent transmission A switch provides selectively connection state between the optical-receiving unit and the main optical-transmitting unit and between the optical-receiving unit and the redundant optical-transmitting unit.
