Abstract:
1. A single chip Ethernet to synchronous optical network interface device comprising: at least one optical carrier framer for performing transmit framing on a channelized input data stream producing a transmit data stream for conversion to an optical signal for transmission over an optical network link, and for performing receive framing on a receive data stream converted from an optical signal received from the optical network link, producing a channelized output data stream; a cross connect for multiplexing a plurality of input data channels to form the channelized input data stream, and for de-multiplexing the channelized output data stream into a plurality of output data channels; a packet mapper for packetizing at least one of the plurality of output data channels, producing at least one packet output stream for transmission to user equipment over a packet network, and for de-packetizing at least one packet input stream received from the user equipment over the packet network, producing at least one of the plurality of input data channels; a bus interface for connecting additional communications interface devices, the bus interface arranged to permit the transfer of data from at least one of the plurality of output data channels to one or more operably coupled communication interface devices located external to the single chip Ethernet to synchronous optical network interface device, and the transfer of data from the one or more operably coupled communication interface devices to at least one of the plurality of input data channels, the communication interface devices processing the data from the at least one of the plurality of output data channels for transmission using a time division multiplex communication link and processing data received from the time division multiplex communication link for transmission using the at least one of the plurality of input data channels; and at least one embedded microprocessor core that is operable to collect, analyze, and report operational statistics of the single chip Ethernet to synchronous optical network interface device to operating personnel or systems at a location remote from the single chip Ethernet to synchronous optical network interface device, using the optical network link.
