  • Patent number: 7603486
    Abstract: A method and apparatus for detecting the presence and the type of network devices connected to a management device via transmission lines. The apparatus may include a pull-up resistor, a pull-down resistor, a filter, and a presence detector, the resistors superimposing a DC or low-frequency voltage on the transmission line. The impact, if any, of the DC voltage one communications equipment and circuitry can be reduced by a coupling that isolates the DC voltage. Similarly, the filter prevents transmitted data signals from interfering with the DC voltage level. The method and apparatus function regardless of whether the network device is functional or powered on, and different values of pull-up or pull-down resistors can be used to indicate the type of device that terminates the transmission line.

  • Patent number: 7522614
    Abstract: A multi-service access platform may have network interface cards and application cards. The network interface cards may interface the multi-service access platform to an ingress network and an egress network. The network interface cards may be coupled to the application cards by a network distribution bus. As a result, the application cards may perform digital signal processing on signals received from the ingress network. Additionally, the application cards may be coupled to a packet switching fabric. The packet switching fabric may facilitate exchange of signals between the application cards. Additionally, the packet switching fabric may permit exchange of the signals with the egress network.

  • Patent number: 5146592
    Abstract: An image processor having an image algorithm processor (66) operating under control of a writable control store (94), and a number of parallel image processors (72) operating under control of instruction words from a writable control store (100). An image memory controller (68) receives memory addresses from the image algorithm processor (66) for coordinating the reading and writing of an image memory (82) using pixel data processed by the parallel image processor set (72). The image memory controller (68) arbitrates memory address request cycles, memory refresh cycles and screen refresh cycles. The image memory (82) includes different planes (84, 86 and 88) associated with red, green and blue pixel data. Associated with each image memory plane is a video processor (106) for converting parallel image data to high speed serial image data.
