Title: Apparatus for indicating the state of a telephone subscriber line
IPC: H04M3/42
Filed: 1972-11-22
Abstract: 1416547 Automatic exchange systems WESTERN ELECTRIC CO Inc 22 Nov 1972 [24 Nov 1971] 53924/72 Heading H4K In a PBX each extension station is supervised with the aid of a lamp that is illuminated whenever the station goes off-hook or is being rung and which remains illuminated for a predetermined period following an apparent on-hook condition or a cessation of ringing in order to prevent the station from being regarded as free when in fact it is dialling or the ringing is of the intermittent type. The lamps are located in non-locking keys allocated individually to subscribers at an attendant's position. In the line circuit shown, the potential at point 211 is normally - 48 V but this falls to -40 when the line is looped so that Zener diode 201 turns-off. In consequence a multiple element silicon forward threshold diode 207 is forward biased and thus turns on SCR 210 which thereby energizes a lamp 301. During dialling Zener diode 201 is turned-on and off in sympathy but this has no effect on SCR 210 thanks to the presence of capacitor 214 which is able to discharge resistors 209, 215 into the SCR's gate at least for a period of 120 msecs. In the case of ringing, which utilizes bursts of 20 cycle signals separated by 4 second intervals, the Zener diode 201 is heavily reverse biased during positive cycles so that it breaks down in the reverse direction and thus enables threshold diode 207 to turn on SCR 210 as before. The capacitor 214 is much more highly charged than in the case of line looping and is thus able to hold the SCR on between ringing bursts.

C. outputs of several thermocouples P 1 , P 2 , &c. and also provide an instantaneous alarm if any is in error, the outputs are coupled to respective terminals A 1 , B 1 , A 2 , B 2 , &c. of the input switch of a multi line recorder E and also to respective alarm units S 1 , S 2 , &c. incorporating low input impedance transistorized chopper amplifiers F and alarm circuits K, W. The recorder switch has three simultaneously operated wipers M 1 , M 2 , M 3 , of which two, M 1 , M 2 , successively select pairs of input terminals for connection to the recorder, while the third M 3 , connected to M 2 , short circuits the input terminals BC of the respective amplifier F. This connects the terminal B to the base of a transistor in the chopper stage of the amplifier so as to increase the input imedance of that amplifier, so that circulating currents in its input stage do not falsify the values of the corresponding input recorded by the recorder. The input to each amplifier is fed in opposition to reference voltages U 1 <SP>1</SP>, U 2 <SP>1</SP>, etc., the alarm W in the amplifier output being operated if the thermocouple outputs U 1 , U 2 , &c. differ from the reference voltages significantly. A delay circuit D prevents the alarm W from operating during the short periods when the input impedance is raised during connection to the recorder.
