摘要： A Test Access Matrix (TAM) system permits installation onto an existing connector block. The TAM system exhibits a configuration that permits installation on to telecommunications circuits at the connection point provided for installation of protection modules (1) or other devices (1) that are inserted into the telecommunication circuit. The installation can be accomplished either before new or after existing connector blocks are installed on a telecommunication cross connect frame, tie frame, or other support structure. The TAM system can be instructed to connect a two or four wire test bust to any of the individual telecommunication circuits that are connected to the connector block. The test bus can be connected to the individual communication circuits in either a bridging, break towards the distribution side of the local loop, break towards the telecommunications equipments, or an insertion into the line via a 'make before break' sequence.

摘要： An improved fiber optic connector of the type in which a fiber supporting ferrule (15) is slidably and resiliently biased independently of the surrounding load-bearing parts of the connector so that forces applied to the fiber optic cable jacket are not transmitted to the ferrule (15) and supported fiber to interrupt communications then in progress. In one of the embodiments, the needle of a syringe is inserted into a positioning tube (16) which confines an adhesive to the needed area, and prevents wicking of the adhesive to surrounding areas where it might interfere with the sliding action of the ferrule (15). It also wipes the needle as the syringe is withdrawn. A rear body element (13) provided with internal threads (50) which surround the cable jacket, which during a crimping operation, causes the jacket to deform into the threads for superior cable retention. Alternate embodiments include a rear body having means for engaging a sheath of a fiber optic cable, key means, and crimping operations with collet-like fingers.

摘要： A gas tube fail safe device for elongated three element gas tubes having a centrally disposed electrode and a pair of end electrodes. The device includes an elongated planar body (21) having bent up end edges (26-27) forming end electrical contact terminal insulation sleeves (30-31) forming fusible elements. Centrally disposed tabs (33-34) resiliently engage a pin carried by the center electrode of the gas tube. In a second embodiment, a pair of shorting plates (50-51) overlie an air gap insulative member (60) having lines of small orifices (66) which provide air gaps through which excess voltage surges may arc to provide a backup function equivalent to that of the gas tube.

摘要： Dispositif de tubes à gaz à sécurité intégrée pour des tubes à gaz à trois éléments allongés ayant une électrode centrale et une paire d'électrodes d'extrémité. Le dispositif comporte un corps plan allongé (21) ayant des bords recourbés (26-27) qui forment des gaines d'isolation de bornes de contact électriques d'extrémité (30-31) formant des éléments fusibles. Des pattes centralement disposées (33-34) s'accrochent élastiquement à une broche qui est portée par l'électrode centrale du tube à gaz. Dans un deuxième mode de réalisation, une paire de plaques de court-circuit (50-51) recouvrent un élément isolateur à entrefer (60) présentant des rangées de petits orifices (66) qui forment des entrefers à travers lesquels les surtensions peuvent former des arcs électriques afin d'assurer une fonction de support équivalente à celle du tube à gaz.

摘要： A telecommunications fault location and diagnostic system employs a remote test unit (RTU) (2) to collect system parameter data. The RTU is operatively coupled to a trained neural network (30) which receives the system parameter data from the RTU (2). The neural network (3) is trained using pre-screened historical fault data which is stored in a database. Once trained the neural network classifies the RTU data into one of a predetermined number of fault probabilities.

摘要： A coaxial surge protector includes a housing (17) in which is situated a transmission line (10) in the form of a two-sided printed circuit board (20). The surge protector includes input (12) and output (14) signal connectors mounted on a housing and connected to the transmission line (10), and a gas discharge tube (16) electrically coupled between the transmission line (10) and circuit ground. A thermally activated shunt assembly (18) is thermally coupled to the gas discharge tube (16) and senses when the gas discharge tube (16) is in an overheating condition. Upon such condition, the shunt assembly provides an electrically conductive shunt in parallel with the gas discharge tube (16) to divert current flowing through the gas discharge tube (16) to flow through the shunt assembly (18) to ground in order to minimize further overheating of the gas discharge tube (16).
