  • Patent number: 6647024
    Abstract: A communication system and method for supporting both POTS and high speed data services between a remote CPE interface, located at a subscriber premises, and a central office. An analog to digital converter transforms an analog POTS signal to a digital POTS signal, and a combiner circuit combines the digital POTS signal with a high speed data signal into a combined digital signal which preferably has a single communication spectrum. A power detector identifies a power failure at the remote CPE interface, and a life line communication path is established from the central office to the remote CPE interface in response to the power failure.

  • Publication number: 20030193734
    Abstract: Disclosed is an apparatus and method for dynamic fly height and roll adjustment of a physical asperity sensor (PAS) head. The PAS head is used to test disk asperity heights and mechanical interference (commonly known as glide height and take off height). The PAS may be adjusted through a pivoting device such as a joystick coupled through one or more actuators to the pivoting device by actuator arms. In one embodiment, the actuator is a piezoelectric motor. The PAS head may utilize a detector to indicate the distance of the disk asperity from the PAS head. The method comprises receiving the signal and in response, operating the actuators to adjust the position of the pivoting device to obtain a selected positioning of either the fly height or the roll of the PAS.

  • Publication number: 20030177264
    Abstract: It is often desirable to measure performance metrics associated with computing entities such as, for example, computers, computer systems, computing devices, software modules, software layers, or the like. As disclosed, performance metrics regarding remote computing entities may be gathered remotely by routing a network message through specific computing entities of interest, and having the computing entities report performance metrics by adding entries into an editable portion of the network message. That editable portion does not include instructions to be executed by the destination computing entity, but is merely transplanted from the request to the response. In the response direction as well, the response may be routed as originally designated in the request, with each intermediary computing entity in the return path potentially adding an entry with performance metrics.

  • Publication number: 20030154620
    Abstract: A method, apparatus and article of manufacture for providing electromagnetic drying of printed media. A resonant cavity allows support of standing waves along many radial axes throughout the resonant cavity. The electromagnetic drying unit allows forced air to be introduced into the resonant cavity, thereby reducing moisture within the resonant cavity and extending the life of the resonant cavity. Input and output openings may be arranged longitudinally along the resonant cavity and may be designed to substantially reduce the amount of electromagnetic radiation emanating from them during operation. A honeycomb feature at the end of the resonant cavity may allow egress of the forced air, while substantially reducing the amount of electromagnetic radiation emanating from the end of the resonant cavity.

  • Publication number: 20030142815
    Abstract: A digital subscriber line (DSL) compatible plain old telephone service (POTS) line card that interface a telecommunications switching system to a subscriber over a two-wire subscriber line, wherein the subscriber line card detects whether a DSL line card is connected to the subscriber line. A digital signal processor on the POTS line card is configured to process voice-band signals with a first set of parameters if a DSL line card is connected to the subscriber line and to process voice-band signals with a second set of parameters if the DSL line card is not connected to the subscriber line. Detecting the presence of a DSL line card may be performed by sending a voice band tone on the subscriber line and the return loss measured. Additionally, a tone above voice band may be sent on the subscriber line and a return loss measured.

  • Publication number: 20030031239
    Abstract: A method and apparatus for increasing the allowable transmission rate of Digital Subscriber Lines (DSL(s)) in a binder group. The DSL(s) in the binder group are monitored to determine their actual transmission rate. The allowable transmission rate of individual DSL(s) is adjusted in order to make sure that it does not exceed some target level, but that in case many lines are inactive or in a keep-alive mode, that the transmission rate of the active lines can be substantially higher than the transmission rate based on all lines being active and transmitting at their maximum rate. Avantageously, the actual throughput for the binder group can be increased substantially above that allowed for a static assignment of transmission rates.

  • Publication number: 20030026265
    Abstract: A Digital Subscriber Line (xDSL) is used to connect Customer Premises Equipment (CPE) to a telecommunications network. The Customer Premises Equipment generates both Constant Bit-Rate (CBR) and Variable Bit-Rate (VBR) Packets. Each Frame of Packets from the Customer Premises Equipment is used to transmit up to a limited amount of CBR data, and VBR data is used, if available, to fill up the Frame. The limit on the amount of CBR data can be dynamically adjusted according to the need of the CPE. Similarly, and importantly, a limit on CBR data to the CPE can be adjusted dynamicaly according to the need for transmission of CBR data to the CPE. Advantageously, a guaranteed rate of transmission of CBR data can be maintained, even in the face of a flood of VBR traffic. Advantageously, this arrangement improves the quality of service on CBR traffic, such as Voice, and subject to the limit imposed by CBR traffic, allows a maximum amount of VBR traffic to be transmitted.

  • Patent number: 6496566
    Abstract: Metallic testing of a subscriber loop that provides voice and DSL services is provided by a voice switch and DSL services, each of which includes a metallic test unit. A voice line card has a connection to a first metallic test bus connected to the voice switch metallic test unit via a first relay set configured to connect the metallic test bus to the subscriber loop and to disconnect the subscriber loop from the line card during testing. The DSL line card has a connection to a second metallic test bus, which is also connected to the DSLAM metallic test unit, and to the subscriber loop. A second set of relays control the connection of the metallic test bus to the line card to the subscriber loop. A signal is sent from either metallic test unit to cause the relays to change to provide a clear path for metallic testing from DC to light.
