Abstract: Systems and methods that provide visualization of networks. Data is input into a table structure that represents any hierarchy of entities, relationships and their attributes. The content of the table is processed to extract the entities, relationships and their attributes. These are turned into nodes, edges and a visual representation of their attributes using color gradients, categorical colors, shapes, thickness, text labels, etc.

Abstract: A method of monitoring the status of one or more network elements (NEs) linked together in a telecommunication network, comprising receiving a down status notification from a NE in the network, identifying one or more other NEs which are linked to the NE, and polling the or each other NE to determine the status thereof. The status of a NE may be operational, i.e., up, or non-operational, i.e., down. The down status notification may be received from a NE if the NE determines that the status of any other NE linked thereto is down. The down status notification may contain information on the NE which has output the notification. Identifying the or each other NE may comprise accessing the down status notification to obtain information on the NE which has output the notification, and using the information to obtain the identification of the or each other NE. Polling the or each other NE may comprise sending at least one SNMP get request to the NE.

Abstract: A concentric strander has an elongate concentric shaft that defines a shaft axis and supports for rotatably supporting the concentric shaft. A number of wire bobbins are spaced at substantially equal intervals along the shaft to form spaces between the bobbins. Each bobbin has an axis substantially coextensive with the shaft axis for rotation about the shaft, and each bobbin has a maximum radial diameter. The strander has take-off sheaves, mounted on the shaft, that are associated with a wire bobbin and that take the wires from the bobbins and guide them to a point radially outwardly beyond the maximum predetermined radial bobbin diameter. The take-off sheaves subsequently guide the wires in a direction substantially parallel to the shaft axis and define, on rotation of the concentric shaft, a cylindrical envelope. At a downstream end of the shaft, the strander has a closing device that receives the wires from the bobbins and applies them on a core.

Abstract: A concentric tape applicator has a support shaft that defines an axis and includes a structure for supporting a tape pad for rotation with the support shaft about the axis. Guide rollers are mounted on the support shaft for rotation concentrically about the axis for guiding tape from the tape pad for application to an elongated member advancing along the axis relative to the support shaft. A drive is directly coupled to the guide elements. A differential clutch is provided that has an input shaft directly coupled to the drive and an output shaft coupled to the support shaft for applying braking forces to the pad. A feedback circuit is provided for sensing the speed of rotation of the pad and applying a feedback signal to the clutch for regulating the excitation of the clutch to maintain a substantial uniform tension on the tape dispensed from the pad so potentially independently of the amount of tape remaining on the pad.

Abstract: In an apparatus for cable manufacture, a cage strander rotates about a line axis at a chosen rotational speed. Bobbins supported by the strander dispense round conductors downstream of the cage strander. A forming apparatus downstream of the strander receives the conductors and forms them into many complementary segmented preshaped wires each having the desired cross-sectional profile in a final compact conductor. The conductors are positioned in a way that substantially corresponds to the orientations among wires in the final conductor. A first drive rotates the forming apparatus about the line axis substantially at the rotational speed of the strander. A second drive drives the forming apparatus. The drives are synchronized so that the conductors close about the core and cause the sides of adjacent wires to abut against each other to produce both the desired lay and a cable substantially without interstices between the wires forming the twisted conductor.

Abstract: An apparatus for the manufacture of cable is disclosed. The elements of this core include a cage strander arranged for rotation about a line axis at a selected rotational speed. Bobbins are supported by the cage strander and arranged for dispensing round conductors downstream of the cage strander. A forming apparatus is arranged downstream of the cage strander for receiving the conductors and forming them into a plurality of complementary segmented pre-shaped wires each having a desired cross-sectional profiled configuration in a final compact conductor and each defining at least lateral surfaces. The formed conductors are positioned and oriented in relation to each other to substantially correspond to the positions and orientations between such wires in the final twisted compact conductor. A first drive means rotates the forming apparatus about the line axis substantially at the speed of the rotation of the cage strander. A second drive drives the forming apparatus.

Abstract: A multi-wire stranded conductor is formed of a bare wire central core. An intermediate SZ stranded wire is wound on the core, while an outer layer is helically wound on the intermediate SZ wound layer. The intermediate and outer layers assure that the composite conductor maintains a substantially circular cross-section while the helical outer layer also assures the mechanical integrity of the intermediate SZ layer.

Abstract: Concentric Compressed Unilay Stranded Conductors are formed of certain combinations of compressed wires, such as 1+7+12, 1+6+11 or 1+7+12+17, which have nominally equal diameters. The combinations of conductors or wires are selected so that the number of wires in any two adjacent layers, including a central layer, are not divisible by a common number with the exception of the integer one. The stranded conductors are optionally formed to have sectored cross-sectional configurations.

Abstract: A method of and an apparatus for balancing a multi-bay cabler system when less than all of the cabler frame bays are supplied with a supply bobbin are disclosed. The apparatus comprises a mechanical counterweight system which compensates for a depleting strand supply during operation of the cabler system, thereby equalizing centrifugal loading within the rotating strander frame and maintaining its dynamic balance at full design speed during the cable assembly operation. The counterweight system is installed in a bobbin-carrying cradle of an unused cabler frame bay. According to a first embodiment, the counterweight is driven in a linear path relative to the cradle in a direction normal to the rotational axis of the cabler frame. According to a second embodiment, the counterweight is driven in an arc relative to its supporting cradle.

Abstract: Concentric Compressed Unilay Stranded Conductors are formed of certain combinations of compressed wires, such as 1+7+12, 1+6+11 or 1+7+12+17, which have nominally equal diameters. The combinations of conductors or wires are selected so that the number of wires in any two adjacent layers are not divisible by a common number with the exception of the integer one. Compression of wires in one or more layers is such as to provide area reductions within the range from 0 to approximately 19% for the layers affected.

Abstract: An "outside-in" double twist bow buncher includes a cradle which supports two wire receiving bobbins. Wire guides are provided at both axial ends of the machine for receiving and guiding two separate groups of wires and, with a traverse mechanism, laying each group of wires onto a respective bobbin.
