Abstract: A Passive optical network (PON, 8, fig. 1) used to transport traffic signals between a headend (4, fig. 1) and subscriber equipment increases performance and reduces costs while potentially allowing the retention of legacy equipment at the headend and at the subscriber's cable modem. Upstream and downstream traffic signals are converted to upstream and downstream optical wavelengths at customer equipment and headend equipment, respectively, and transported across the PON. The optical signals are converted to electrical signals at the other respective ends, or edges, of the PON, and DOCSIS operation and processing occurs as known in the art. Upstream traffic can be carried at unconventional upstream frequencies. The upper frequency limit of traffic signals is higher than for an HFC thus providing for potentially more channels, either upstream or downstream.

Abstract: A flow bonder at a CMTS and another at a cable modem distribute packets of a service flow over multiple channels and collect them in the downstream direction respectively; vice versa in the upstream direction. The collector uses a service flow identifier and a sequence number identifier inserted by the distributor into each packet of the flow to reassemble the packets into the order they left the distributor. Packets received at the collector are stored to a buffer. If a stored packet is the next to be transmitted, it is transmitted. If not, the collector waits a predetermined period until the next packet to be sent is received. If it is not received during the wait period, the previously stored packet is sent. The wait period is based on the maximum transmission time difference between any two of the multiple channels.

Abstract: A device receives packets associated with a program stream at an addressable communications port, and assigns them to one of a plurality of QAM channels. Multiplexed program packets, DOCSIS data or multimedia packets or a combination of both, are transmitted over the QAM channel. DSG messaging transports requests for content to a server, transports queries to mapping tables and returns information from the tables to a manager that, along with processors, determine which channel to use for downstream transport of the multiplexed streams. The manager assigns a connection identifier corresponding to a channel and program number combination to the packets, and sends the identifier, via DSG, to the requesting/receiving user device; the identifier instructs the user device how to tune and receive the requested packets. The identifier may use seven bits for program numbers, two for output port number and two for channel frequency.

Abstract: The clocks of one or more edgeQAM devices are synchronized with a master clock at the remotely located CMTS. A master clock signal may be transmitted via a dedicated gigabit Ethernet link. Alternatively, master clock information contained in a time synchronization message may be transmitted for use in adjusting local oscillators that drive local clocks at respective edgeQAM devices. In another embodiment, the downstream sample rate to particular edgeQAM devices may be sampled and used to lock a local clock at respective canary modems dedicated to each edgeQAM device. A canary modem's clock is compared to the master clock, and a resulting phase error is communicated to the respective edgeQAM device for use in adjusting its local clock. Or, TDMA upstream ranging burst average trends are used to estimate edgeQAM clock error. Each respective edgeQAM uses this error to adjust its clock.

Abstract: A system transports a single video stream from a video server over a WAN to a replicator at a specified IP address. The specified address may correspond to a RTP or UDP/IP address of an endpoint or port. A table at the replicator associates a plurality of downstream QAM channel frequencies with the specified address and the replicator creates as many copies of the stream as there are QAM channels associated with the IP address. The copies are forwarded to each of the QAM modulators that are tuned to one of the frequencies that are associated with the IP address. Grooming is done at each of the QAM modulators according to rules that correspond to the channel.

Abstract: An active optical network switch (4) having a switch module, a plurality of uplink modules and a plurality of downlink modules connected to a backplane for connecting the modules and passing signals among them. A CPU module assists in managing the routing of traffic signals by the switch module; said modules and backplane are enclosed in an environmentally hardened housing. Six downlink modules may include four downlink ports each, for connecting the switch to twenty-four subscribers (20 and 56). Multiple switches may be daisy-chained together; one being a master and the remainder being slaves, to increase the number of subscribers (20 and 56) that are served by an uplink fiber/pair (58). Dense Wavelength Division Multiplexing may aggregate traffic signals between many subscribers (20 and 56) and a CO/head end along a single backhaul fiber (58). Switch software may provide "network edge" functions including traffic shaping, policing, filtering and aggregation, and address control.

Abstract: A direct broadcast satellite system delivers video content to a subscriber and a CATV network is used to simultaneously provide data services to the same subscriber. Since the CATV system is not used to deliver video/television programming channels, these same channels can be used to transport downstream and upstream data signals. To provide upstream performance and immunity to noise, upstream data traffic signals from a subscriber's cable modem are upconverted for transmission by channels having center frequencies higher than 42 MHz. Circuitry combines the original output signal from the cable modem (52) with the output of a local oscillator (62) to raise the carrier frequency of upstream traffic before being introduced to the CATV network. Thus, upstream traffic is carried by channels higher than 42 MHz. This upstream signal is received by a block converter that lowers the carrier frequency back to a conventional channel frequency before processing by a standard CMTS.

Abstract translation: 直接广播卫星系统向用户传送视频内容，CATV网络用于同时向同一用户提供数据服务。 由于CATV系统不用于传送视频/电视节目频道，所以这些相同的频道可用于传输下行和上行的数据信号。 为了提供对噪声的上行性能和抗扰性，来自用户的电缆调制解调器的上行数据业务信号被上变频以通过具有高于42MHz的中心频率的信道进行传输。 电路将来自电缆调制解调器（52）的原始输出信号与本地振荡器（62）的输出组合，以在引入到CATV网络之前提高上行流量的载波频率。 因此，上行流量由高于42MHz的信道承载。 该上行信号由块转换器接收，该块转换器在由标准CMTS处理之前将载波频率降低回常规信道频率。

Abstract: Cable modem main processor and RF circuitry is turned off during off-site power loss when an RF communication channel is absent. A timer periodically wakes up the process to determine whether an RF channel has been restored. A controller implements the timer and interacts with an RF detector. These components use less power than the main processor circuitry. Accordingly, energy is conserved while the processor is asleep. If AC power is restored while the timer counts, the processor is awakened. If an RD channel is detected while awake, the modem reboots into ready mode. The RD detector supplements the timer to wake up the processor if RD energy is detected so the processor can scan for potential RF channels before the timer finishes counting. The RF detector and RF circuitry of the processor may share passive components such as a coupler, filters and diplexer.

Abstract translation: 当RF通信信道不存在时，电缆调制解调器主处理器和RF电路在场外功率损耗时关闭。 定时器周期性地唤醒该过程以确定RF信道是否已被恢复。 控制器实现定时器并与RF检测器交互。 这些组件比主处理器电路使用的功率更少。 因此，在处理器睡着时节能。 如果定时器计数时AC电源被恢复，则处理器被唤醒。 如果在唤醒时检测到RD通道，则调制解调器将重新启动到就绪模式。 RD检测器补充定时器以唤醒处理器，如果检测到RD能量，则处理器可以在定时器完成计数之前扫描潜在的RF通道。 处理器的RF检测器和RF电路可以共享诸如耦合器，滤波器和双工器的无源部件。

Abstract: Cable modem circuitry is connected via a bus interface to decoder circuitry in a set top box to receive various types of content and distribute the content to outputs corresponding to the content type. The outputs include video, audio, data (USB host), telephony and asynchronous interface. The content is received on a single broadband connectin from a single service provider rather than multiple connections from multiple service providers. The DOCSIS protocol, and features that are a part thereof, are used to facilitate efficient transmission of content to a subscriber. Content, including telephony, video, audio and data may be stored or received at a provider's central location for subsequent transmission to a subscriber in response to a request for the content. DOCSIS DsX and DCC at the cable modem are used to enhance the performance and quality of service of the delivery of content.

Abstract: A genetic processor is used to process a plurality of baseband signals in a communication system. Signals received at an antenna array are processed to form chromosomes based on signal-to-interference-and-noise ratios. The chromosomes are further processed to determine a fitness of the chromosomes, and a weight set corresponding to a determined best fitness level is used to selectively process each signal to corresponding to each antennae of the array to increase the dynamic range of the receiver. In-phase, quadrature, amplitude and phase are signal characteristics that may be processed. In the transmit direction, the chromosomes are used to process the modulating signal supplied to each RF antenna, thus resulting in beamforming, the actual signal processing occurs digitally in the baseband spectrum. Chromosomes comprise a number of genes, or bits, based on the type of encoding scheme and the polarization, number and array grouping of antenna elements.
