  • Patent number: 8019587
    Abstract: A method for upgrading redundant network components is disclosed. An application is installed on a network component. The network component is related as a redundant peer with a mate network component operating in an active mode and processing a stable call. The network component is placed in a standby mode. Data of a first version is transferred from the mate network component to the network component. The transferred data is converted from the first version to a second version. The mate network component is switched from the active mode to a standby mode. The network component is switched from the standby mode to an active mode to process the stable call.

  • Patent number: 7568125
    Abstract: In accordance with one embodiment of the invention, a method for replicating data for redundant network components is disclosed. Data associated with a call is received and stored in a shared memory database. The data is sent to a mate network component of the network component if the network component is in an active mode. Sending of the data to the mate network component is terminated if the network component enters a mode other than the active mode.

  • Patent number: 7007190
    Abstract: A method for replicating data for redundant network components is disclosed. An entry of a replication table of a shared memory database is assigned to a stable call. The replication table is associated with a network component operable to process the stable call. Data associated with the stable call is received and is stored in the shared memory database. The entry is updated in response to storing the data. The data is sent to a mate network component of the network component, and the entry is updated in response to sending the data.

  • Patent number: 4766517
    Abstract: An avionic tray adapted to be made in several width and sizes including standard ATR widths is made from aluminum alloy sheet which had beads or corrugations to compensate for decreased overall width of the sheet. Typically, the sheet is made from 0.040" thick 6061-T6 aluminum alloy, and the beads or corrugations increase the effective apparent thickness of the sheet to the usual tray thickness of 0.063". In a bottom section of the tray the beads run substantially parallel with the longitudinal axis of the tray, but do not extend to a deformed area where a metering plate is mounted. In side rails of the tray one bead runs parallel with the longitudinal axis, and the rest of the beads are disposed parallel with an edge of the side rail which is itself at an acute angle to the longitudinal axis of the tray. Jig pins provided in the side rails of the tray comprise extrusions of the material of the side rail which surround punched-out holes in the material.
