  • Patent number: 5623541
    Abstract: An Operations Support System, comprised of a computer and workstation, stores digit analysis specifications for telecommunications call processing. A graphical user interface displays digit analysis specifications visually as subtrees made up of nodes representing the digits of the dialed number. Two subtrees can be displayed contemporaneously for evaluation and manipulation independently and from one to another. Operations performed on the nodes also operate on the embedded digit analysis specifications permitting manipulation of the specifications without the need to view or deal with the specifications themselves directly. Related information such as Routing Table Indexes and local exchange numbers called NXX numbers are displayed contemporaneous with display of a subtree of interest and are manipulated with regard to that subtree.

  • Patent number: 5440626
    Abstract: An end office of the PSTN, which employs independent switching networks which share one or more office codes, is served by a single assigned node on the CCS network. The signaling processor which serves the assigned node, screens all incoming call messages (IAM)'s; directs messages which include an appropriate Channel Identification Code (CIC) to the switching network that serves that CIC; rejects messages that include an improper CIC; and requests that the calling office assign a different CIC to the incoming call. In an alternate configuration, a signaling message intercept unit is interposed between a signal transfer point (STP) and end switches, to determine which of two or more switches should receive a message, based on the directory number, a circuit identifier or a message index of the received message, and forwards the message to the correct switch.

  • Patent number: 4597127
    Abstract: A hydraulically driven rotary brush for cleaning vehicles and the like. This is a rotary brush system wherein the brush rotates about an axis parallel to the item being washed. It has a wand for the attachment to a source of water at one end, and a brush mounted at the further end. Water flowing through the wand is diverted into a channel or channels for the operation of at least one turbine unit connected to the drum supporting the brush. Water exiting from the turbine unit is directed onto the surface being washed to thoroughly flush the same. The drum is provided with means for inserting detergents and/or waxes within the drum, and apertures are provided within the surface of the drum whereby these materials can be fed to the brush whereupon they mix with the water for application to the surface. Provision is made whereby the drum can be readily removed, for example, for the replacement of the bristles or elements of the brush itself.
