摘要： A cable modem integrated session border control circuit operates as a point of demarcation between a local area network (LAN) and a DOCSIS network and, in response to receiving a Session Initiation Protocol (SIP) message, which includes Session Description Protocol (SDP), from a VoIP device coupled to the LAN, communicates with a Cable Modem Termination System (CMTS) to take advantage of DOCSIS Dynamic Quality of Service (DQoS) if a VoIP session between the VoIP device and a remote endpoint includes use of the DOCSIS network. The cable modem integrated session border controller further determines required service flow attributes. If required service flow attributes, as determined from the SDP of the SIP message, matches service flow attributes of an existing UGS service flow with a CMTS, a DOCSIS Dynamic Service Chance (DSC) request is used to add an additional sub flow to the existing UGS service flow. If attributes fail to match attributes of all existing UGS service flows, a DOCSIS Dynamic Service Change (DSC) request is used to initiate an additional UGS service flow with the required service flow attributes.

摘要： An electronic device with improved heat dissipation properties comprises metallic housing. A base circuit board may be positioned within the housing in a plane parallel to the backside. Multiple connectors for coupling cassettes to the base circuit board may be positioned about the periphery of the base circuit board such that multiple cassettes may be positioned adjacent to each side of the housing. Each cassette includes a printed circuit board with a plurality of heat generating components coupled to the printed circuit board and having a thickness extending towards the side of the housing. The cassette includes a metallic housing with a heat dissipation structure contacting: i) the side of the housing; and ii) each heat generating component. Each of at least two heat generating components have different thicknesses and the heat dissipation structure had different thicknesses between the side of the housing and each heat generating component.

摘要： A system and method enable wireless communication from one data processing system to a telephone network. The system and method establish a connection from a local transceiver to a base transceiver using echo cancellation techniques to remove various tones and noise. The system and method enable full duplex communication between the local transceiver and the base transceiver by using forward error correction algorithms to encode and decode messages therebetween, and by using an interleaving algorithm to protect against burst type errors.

摘要： A digital wireless communication system operates between a first unit and a second unit. The received digitally encoded signal is sampled to produce a first sampled digital signal. A first bank of match filters with each match filter having a different frequency range is used to pass the first sampled digital signal therethrough. The output of the first bank of match filters having the largest amplitude is selected along with the match filter which produced the largest amplitude output. The digitally encoded signal having this "coarse" frequency range is then passed through a second bank of match filters. Each of the match filters has a fine frequency different from one another. The output of the second bank of match filters is produced and the output having the largest amplitude is selected. In addition, the filter producing the largest amplitude from the second bank of match filters is also selected.

摘要： In a digital wireless communication system, a first unit transmits a digitally encoded signal to a second unit in a plurality of non-contiguous time slots. Within each time slot, the digitally encoded signal has a synchronization signal portion followed by a data signal portion. The second unit has an antenna to receive the synchronization signal portion of the digitally encoded signal. The second unit also has a clock to generate a clock signal at a first rate having a sampling phase. An analog to digital converter receives the clock signal and the synchronization signal and samples the synchronization signal at the first rate to generate a first plurality of symbols. An interpolator receives the first plurality of symbols and interpolates the first plurality of symbols to generate a second plurality of symbols at a second rate. The second rate is a multiple of the first rate. A match filter receives the second plurality of symbols and compares the second plurality symbol of symbols to a stored plurality of symbols to generate an error signal. The sampling phase of the clock signal is altered in response to the error signal, after to the receipt of the synchronization signal.
