摘要： A method and apparatus for monitoring telecommunication lines. A switch is disposed between the telecommunication lines to be monitored and a jack which is connectable to a signal monitoring device. The switch is positionable into a neutral position for permitting connection of the signal monitoring device to the jack and at least a second position where the signal monitoring device may monitor the signals of the telecommunication lines.

摘要： A printed circuit board has two contact areas on each surface near one end. The board is sandwiched between two halves of a shell to form a plug in such a way that the contact areas are exposed. The contact areas on one surface are nearer the exposed end than the contact areas on the other. The tip and ring conductors of a pair of wires in a test cord are connected, respectively, with the two contact areas which are nearer the exposed end. A keeper spring which is connected to the shield of the jumper cable, the ground potential, insures that the plug will be retained within a jack into which the plug is inserted by engaging a detent. The detent is connected to ground potential. The jack has two long electrical contacts and two short electrical contacts. The long electrical contacts engage the two contact areas which are farther away from the exposed end and the two short electrical contacts engage the nearer contact areas. A circuit housed within the plug insures that when the plug is inserted within a jack, a tracing lamp associated with the jack will flicker for a predetermined period.
摘要翻译： 印刷电路板在靠近一端的每个表面上具有两个接触区域。 板被夹在壳的两半之间以形成插头，使得接触区域被暴露。 一个表面上的接触区域比另一个表面上的接触区域更接近暴露端。 测试线中的一对导线的尖端和环形导体分别与更接近暴露端的两个接触区域连接。 与跳线电缆的屏蔽层连接的保持器弹簧，即接地电位，确保插头通过接合制动器而保持在插头插入插座中。 制动器连接到地电位。 插座有两个长的电触点和两个短的电气触点。 长电触头接合远离暴露端的两个接触区域，并且两个短电触头接合更近的接触区域。 容纳在插头内的电路确保当插头插入插座时，与插孔相关联的跟踪灯将闪烁预定时间。

摘要： A connection switch jack has first and second sets of pins, and a set of spring contacts for connecting the first and second sets of pins when the spring contacts are in a normally closed position. The jack has a receptacle for receiving a plug having a plurality of plug contacts, wherein receipt of the plug connects corresponding plug contacts to selected pins of the first set of pins via the spring contacts and then moves the switch off of the normally closed position to break the contact between the first and second sets of pins.

摘要： A printed circuit board that reduces parasitic effects on devices mounted thereon. The printed circuit board comprises a top layer and a bottom layer of a first insulating material having a first dielectric constant. The layers are configured to form holes whereby each of the holes has a first part extending through the top layer and a second part extending through the bottom layer. The bottom layer is further configured to comprise a second insulating material having a second dielectric constant, which second insulating material surrounds the second part of the hole. The devices mounted onto the printed circuit board have pins that extend through the holes. When the second dielectric constant is less than the first dielectric constant, the parasitic effects on the pins of the mounted devices are reduced.

摘要： A cable retainer assembly for retaining cables in a cable trough includes an elongated member that can be detached and secured to a trough. The member has a receptacle disposed at least partially along a length of the member. In one embodiment, the receptacle is a U-shaped channel which extends along the length of the elongated member. A retainer includes a flange that can be inserted in the receptacle and is sidable along the length of the receptacle. A second channel is provided for detachably securing the elongated member to a cable trough. A third channel may be provided on a front face of the elongated member for retaining a designation chart. The chart may be marked to indicate cable designations.

摘要： A coaxial jack with an internal switch mechanism includes a cylindrical shell having an axial front opening, and an elongate center conductor supported coaxially inside the shell. A back end of an elongate resilient switch contact is fixed by a switch contact support at a back portion of the shell on one side of the shell axis. The switch contact extends inside the shell toward the front opening at a certain inclination and has a free end located on a side of the shell axis opposite the one side. The switch contact is configured and positioned to make an electrical connection with the center conductor in the absence of a mating plug. An elongate actuator is supported on the inner periphery of the shell and has an engaging part that protrudes into a defined plug travel path inside the shell. The engaging part is configured to cause the free end of the switch contact to deflect by an amount sufficient to break the electrical connection between the contact and the center conductor when a mating plug travels into the shell and displaces the engaging part of the actuator.

摘要： A digital cross-connect module with a housing formed of two portions which slidably engage one another. One of the portions includes tabs which engage slots formed in the other portion. The two portions are formed of plastic, so the module housing is lighter and easier to produce than conventional housings. The housing contains a printed circuit board (PCB). The PCB has a first plurality of jacks adjacent the front of the housing and a second plurality of jacks adjacent the rear of the housing for cross-connecting digital signals.
