Title: Apparatus for blocking cialling by a telephone subscriber
IPC: H04M3/38
Filed: 1971-09-22
Abstract: 1371909 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 22 Sept 1971 [9 Nov 1970] 44194/71 Heading H4K In a PABX means are provided for monitoring dialling impulse trains so as to initiate a calls barred condition in the event that the j th  digit has a particular value. Barring may be effected for particular combinations of the first n digits or even for any combination of digits i.e. when an extension is only permitted to take part in incoming calls. In addition barring is effected if dialling is attempted before the arrival of local or main exchange dialling tone. Looping of the line and dialling impulses are repeated by contact s in the input circuit of a pulse shaper RI whose upper output into diode d 1  comprises a rectangular pulse train where the leading edge of each pulse is delayed relative to that of the initiating pulse whereas its trailing edge coincides therewith and whose lower output into bi-stable B2 results in line looped and line unlooped signals being presented via amplifiers A4 and A3 respectively. The resistance, diode, transistor and amplifier network d1, I2 integrates the shaped pulses to provide a rectangular pulse α whose duration represents the value of a dialled digit while the differentiating networks 13 ... A2 provide a pulse signal # at the end of each impulse train and an inverted pulse γ which is slightly delayed with respect to #. The shaped pulses are counted in binary counter C which is stopped and read-out via decoder dec when an end of train pulse # appears and then cleared when delayed pulse γ occurs. The decoder supplies each digit value to a logic unit, Fig. 4, which includes a binary counter C 0  that determines the order of each digit i.e. first, second, third &c. utilizing the integrated pulse α as its step-on signal. The outputs of C 0  and dec are interpreted by the logic Z so as to enable a call barring relay R2 or a "remove monitor" bi-stable B7 depending on whether the dialled digit(s) is or is not permitted. The contacts of R2 effectively disconnect the PBX extension from the seized exchange line (Fig. 1, not shown). The lower portion of Fig. 3 depicts a circuit which responds to dial tone supplied from the subscribers line via capacitors Cs. The tone signal is integrated to ensure that it is genuine and used to set bi-stable 84 and thereby close NOR gate N 8  which would otherwise permit dialled impulses to actuate the call barring relay. If the subscriber attempts to make another call by gaining access to a distant exchange which reverts him a new dialling tone (it being remembered that on a legitimate call i.e. after the first n digits, the monitor is normally inoperative), reception of dial tone counter CS responds and via NOR gate N 9  actuates the call bar relay.

Title: Digital data handling system
IPC: H04L12/423
Filed: 1971-09-25
Abstract: 1356269 Interrupt handling INTERNATIONAL BUSINESS MACHINES CORP 25 Sept 1971 44775/71 Heading G4A A data handling system comprises a controller 1 and a plurality of input/output modules connected in a loop between a first interrupt condition terminal 4A and a second interrupt condition terminal 4B on the controller by means of a sequence line 2 which enters each module by a first terminal and leaves it by a second terminal, each module being adapted to energize one and both terminals in response to first and second interrupt conditions respectively, to transmit from each terminal signals received at the other, and to respond to the signals applied to the sequence line by the other modules to develop a signal indicative of the priority of an interrupt condition requiring energization of one or both of its terminals relative to the priority of similar conditions occurring within other modules. Two categories of interrupt, high and low, may be serviced by the system with the modules arranged in descending order of priority within the high category M 1 , M 2  ..., M n  and in descending order Mn, M n-1 , ..., M 1 , in the low category. Each module contains two bi-stables with outputs H and L, H being set to 1 for a high level interrupt and L for a low level interrupt in the corresponding module. A further bi-stable generates a signal Z indicating that the module is generating the highest level priority interrupt within the system and must therefore transfer its identity, over line 2, to the controller. When a module generates a high level interrupt it transmits a signal in both directions and when it generates a low level interrupt it transmits it only towards terminal 4A. The value Z within a module must be 1 when that module generates a high level interrupt if no high level interrupt exists on its left and when it generates a low level interrupt if no interrupts of either category exist to its right and no high level interrupt exists to its left i.e.: Each module transmits from each of its terminals signals received from other modules at the other terminal so that: Pi = 1 when Pi + 1 = 1 and Qi= 1 when Qi - 1 = 1. To implement these equations a module must detect the value of Q to its left and of P to its right and a transistor circuit is described to accomplish this by detecting the potential and direction of current flow in the two segments of sequence line to which the module is connected. A circuit is also described for use in the controller for detecting when P 1  = Q n  = 1, i.e. a high level interrupt is present, and P 1  = 1 and Qn = 0, i.e. a low level interrupt is present.
