  • Patent number: 10225196
    Abstract: A system for use in nodes communicating over a CPRI (common public radio interface) allows each networking node in a daisychain configuration to seamlessly manage the control and management HDLC (high-speed data link control) channel for both uplink and downlink. The connection is kept alive through a soft reset flow. Received HDLC packets can be extracted for use by a local node. Locally generated packets can be inserted into the packet data stream at the datalink layer for onward transmission over the CPRI. The system arbitrates between the locally generated packet data held in a buffer in the local node and remote packet data received from a remote node and held in the local node in a first in first out buffer for onward transmission to a subsequent node after arbitration. Remote packet data is given priority.

  • Patent number: 6931028
    Abstract: A method for high quality voice communication over an IP network. The method is implemented using an IP network device. Voice communication quality of service is initiated through the transmission of a path message for the voice communication. The path message is configured for establishing a communications path through the nodes of the IP network. A reservation message is received in response to the path message. The reservation message is configured for specifying a range of voice streams for a bandwidth reservation, allowing a single reservation message to specify bandwidth for quality of service for multiple voice calls. The bandwidth reservation for the range of voice streams is implemented in accordance with the reservation message. The path message can be transmitted from an originating IP network device, such as an originating VoIP gateway, and can be generated by a first voice application executing thereon.

  • Patent number: 6721317
    Abstract: Several embodiments of a computer system are described which achieve separation of control and data paths during data transfer operations, thus allowing independent scalability of storage system performance factors (e.g., storage system iops and data transfer rate). In one embodiment, the computer system includes a data switch coupled between a host computer and one or more storage devices. A storage controller for managing the storage of data within the one or more storage devices is coupled to the switch. The switch includes a memory for storing data routing information generated by the controller, and uses the data routing information to route data directly between the host computer and the one or more storage devices such that the data does not pass through the storage controller. Within the computer system, information may be conveyed between the host computer, the switch, the one or more storage devices, and the storage controller according to a two party protocol such as the Fibre Channel protocol.

  • Patent number: 6700886
    Abstract: An asynchronous serial crosspoint switch is word synchronized to each of a number of transceiver circuits. The crosspoint switch circuit generates both a master bit clock and a master word clock signal. A transceiver circuit recovers the master bit clock signal from an incoming high-speed serial data stream using a clock and data recovery circuit. The recovered bit clock signal is used as a timing signal by which data is serialized and transmitted to the crosspoint switch circuit. The data stream transmitted to the switch circuit is frequency locked to the master bit clock signal, such that the serial data stream need only be phase adjusted with a data recovery circuit. To recover word timing, the switch circuit issues alignment words to the transceivers during link initialization. The transceivers perform word alignment and establish a local word lock. Alignment words are then reissued to the switch circuit using the local word clock.

  • Patent number: 6584079
    Abstract: An arrangement for implementing a network in an ISDN-BASED customer premises having a 4-wire ISDN S0 bus. The ISDN-BASED customer premises includes a Network Termination Basic Access (NTBA) that interfaces between the residential customer premises and the public switched telephone network by mapping the 2-wire ISDN signal onto the 4-wire bus. A low pass filter is added to the 2-wire send path to eliminate high frequency noise caused by harmonic reflections of the ISDN-based signals on the 4-wire bus. The filter also provides a delay between the zero crossing of the ISDN-based signals and the transmitted network signals, minimizing the effect of the ISDN zero crossings on the home network signal.
