  • Method and arrangement for controlling alternative routing of traffic in a circuit-switched network
    Patent number: 6606380
    Abstract: The method comprises receiving call signalling in a node and routing the call in accordance with the call signalling. If congestion is met, it is decided whether an alternative routing is allowed in dependence on parameters associated with the call and the node and the call is routed in accordance with such allowed alternative routing. If congestion is met again or no alternative is allowed, it is decided if the call should be released or subject to crankback, dependent on parameters associated with said call and node. By receiving indicators with the call signalling, indicating the types of alternative routing performed in preceding nodes and using said indicators as parameters for the above decisions, and updating said indicators for each call whenever alternative routing is performed for said call, the alternative routing can be controlled in an improved and simple manner. Several types of alternative routing may be available in the nodes.

  • Cable seal
    Patent number: 5625167
    Abstract: A method of forming a cable seal which includes positioning a sealing material around the cable, positioning a housing around the sealing material, and subsequently positioning at the housing a restricting element that can restrict movement of the sealing material out of an outlet of the housing. The restricting element is a snap or interference fit to the housing and extends to the outlet.

  • Re-enterable enclosure around splice
    Patent number: 4924034
    Abstract: A butt cable splice is environmentally sealed by a closure that may be integrally blow-moulded, but which can be cut for re-entry and then resealed by partially telescoping together the resulting parts.

  • Method of forming a wraparound closure article
    Patent number: 4409177
    Abstract: A wraparound closure article comprising a slit tubular body having upstanding rails extending along the slit is formed by a combination of blow-and compression-moulding. The rails are formed by compressing a longitudinal edge portion of a parison between two parts of a closed split-mould to form a flange, and the tubular body is formed integrally with the rails by blowing the remainder of the parison into contact with the closed mould. The flange is then cut to provide the slit of the wraparound closure article and to divide the flange into two discrete rails. The slit extends along the pinch-line that forms as a result of compressing the edge portion of the parison in the closed mould.
