摘要： An electrical connector jack having an outer cylindrical housing and a central coaxial conducting member which is slidable along its axis when receiving a plug so as to complete a contact with a second central coaxial conductor and simultaneously open a switch connected to a second central coaxial conductor so as to disconnect a terminating resistance or an alternate circuit path. The second conductor is connected so that there is no unused stub to cause reflections.

摘要： Telephone line testing equipment in which a series of alternating current tone pulses are transmitted from the central office along the line to a sensing means placed at a remote point in the circuit. The series of pulses are transmitted in a coded sequence. The sensing means receives the pulse sequence, decodes it, and connects the telephone line to suitable loopback testing circuits if the proper code is received.

摘要： Apparatus is provided for remote testing of the condition of a telephone communication line to the point of interfacial connection between the line and customer equipment. The apparatus includes sensing means responsive to a trigger signal inserted onto the line at the telephone company end, the trigger signal being an alternating current tone burst of a given frequency, given minimum time duration, and given minimum voltage level. The sensed trigger signal activates a switch means at the point of customer interface, with the switch means in its quiescent, first condition maintaining the integrity of the line and in its second, activated condition disconnecting the line and inserting onto the line for a given period of time a given electrical impedance and a disconnect indicator. The sensing means is responsive to the presence of the trigger signal independent of the condition of any equipment beyond the point of customer interface when the switch means is in its first condition. Means for testing the condition of the telephone line with the given electrical impedance on the line are provided at the telephone company end of the line.

摘要： A telephone equipment jack panel for use in circuits where high voltages may be present wherein each jack is surrounded by and enclosed in a plastic support. A plurality of these supports are mounted in a row on a base and further enclosed by a cover which provides access to the jacks only through holes positioned a predetermined distance from the entrance ends of the jacks so that the jacks may be reached only by the insertion of a special highly insulated plug.
