摘要： A plurality of CMTS devices are linked together and synchronized to facilitate communication between the respective CMTS devices and respective downstream cable modems. According to one embodiment of the invention, one of the CMTS devices is designated as a master device, and the other CMTS devices are designated as slave devices. The respective CMTS devices are connected to each other by means of a synchronization bus. The master CMTS device then generates and broadcasts a future time stamp value, which is received by the respective slave CMTS devices. When the time stamp counter in the master CMTS device reaches the transmitted value, a control signal is broadcast over the synchronization bus. The slave CMTS devices then retrieve the time stamp value and reset their respective local time stamp counters to the received value. In this manner, the CMTS devices are synchronized.

摘要： Upstream requests such a bandwidth requests, are processed by CMTS out of order on a priority basis to reduce latency in responding to the request. Specifically, a cable modem termination system (CMTS) is connected to a plurality of cable modems by a cable plant. The CMTS has a burst receiver adapted to be connected to the cable plant to process upstream data packet units and bandwidth requests transmitted by the cable modems. Each packet includes a header that uniquely distinguishes the bandwidth requests from other data types. Packet data units are arranged in a first memory queue. Bandwidth requests are arranged in a second memory queue. The headers of the packets processed by the burst receiver are inspected as they arrive at the CMTS to determine if the packets are packet data units or bandwidth requests. Packet data units are routed to the first memory queue. Bandwidth requests are routed to the second memory queue. Bandwidth allocation MAP messages are generated from the bandwidth requests stored in the second queue and transmitted downstream to the cable modems. The packet data units stored in the first queue are coupled to a data output for further distribution.

摘要： Data packets transmitted over a wireless network are suppressed by hardware at the transmitting end and expanded on the receiving end. This conserves bandwidth as well as reduces the processing resource requirements in both the subscriber station and the base station. An extended header element is added to a data packet that is to be transmitted over the wireless network. The extended header element contains an index that is used along with an identifier to access a rule. The rule is used to determine which bytes are to be suppressed at the transmitter and expanded at the receiver.

摘要： A serial packet sync encoder is used to encode a serial packet sync datastream. In an embodiment, the serial packet sync datastream is made up of the packet sync vector and a unique preamble bit sequence that is preselected. In another embodiment, the serial packet sync datastream is made up of a non-unique bit sequence. A serial packet sync transmitter is used to transmit the serial packet sync datastream. A serial packet sync receiver is provided for receiving the serial packet sync datastream. In an embodiment, the serial packet sync transmitter and the serial packet sync receiver are shift registers. In this way, the serial packet sync datastream can be transmitted and received using only a single pin. The serial packet sync datastream is useful for providing an indication that an event, such as a grant arrival, has occurred. A preamble comparator is provided to compare the received serial packet sync datastream and the preselected preamble to determine if the two match. In cases where a match is made, the packet sync vector is written into a holding register for access from other applications and or system components such as a digital signal processor.
