    摘要： A media converter is coupled to an optical link terminal and a plurality of coax network units in a cable plant. The media converter receives packets from the optical link terminal via an optical link. The packets include first packets addressed to coax network units on the cable plant and second packets addressed to network units outside of the cable plant. The media converter forwards the first packets to the coax network units on the cable plant via one or more coax links, such that the first packets are forwarded to each coax network unit on the cable plant, and discards the second packets.

    摘要： A media converter is to be coupled to an optical line terminal via an optical link and to a plurality of coax network units via coax links in a cable plant. The media converter includes an optical physical-layer device to receive and transmit optical signals via the optical link and a coax physical-layer device to receive and transmit electrical signals via the coax links. The media converter also includes an implementation of an optical-coax convergence layer to schedule transmissions of electrical signals from the plurality of coax network units by allocating coax resources among the plurality of coax network units in accordance with resource allocation for the optical link.

    摘要： A system and method is provided for obtaining a message type identifier embedded in a vocoder packet via a speech codec (in-band) such as found in a wireless communication network. The vocoder packet is received and decoded. The decoded vocoder packet is filtered until a synchronization signal is detected, with the filtering comprising correlating the decoded vocoder packet with a predetermined sequence to generate the synchronization signal. The polarity of the synchronization signal is determined, and the message type identifier is derived based on the polarity of the detected synchronization signal. A first polarity identifies a first message type, and a second polarity identifies a second message type.
