Title: Improvements in or relating to arrangements for signalling or impulsing in multiplexpulse communication systems
IPC: H04J3/12
Filed: 1954-05-19
Abstract: 753,394. Pulse signaling. TELEFONAKTIEBOLAGET L.M. ERICSSON. May 19, 1954 [May 20, 1953], No. 14754/54. Class 40 (5). Each channel demodulator in a multiplex pulse communication system actuates a relay, which is released to connect a local signalling source to the outgoing channel when the demodulator receives a particular signalling input and when all, or a predetermined number, of channel pulse trains disappear, relay means prevent the signalling source from being used. In one embodiment, the channel demodulators 11, 12, 13 fed from the input 1 and distributer 2 are connected to relays '31, 32, 33, respectively, and to a common relay 30. When a channel pulse train is suppressed for signalling purposes, the appropriate relay, e.g. 31, releases to connect the signalling source 3, through the closed contacts 40 of relay 30 and the now closed contact 41 of relay 31 to the point 61 of the outgoing channel. If all, or a great number, of the channel pulse trains disappear, relay 30 releases to open contact 40 and disconnect the signalling source 3. In another embodiment, the relay 30 is omitted and each channel relay when operated completes a circuit between a common line from source 3 and a common conductor from which the signalling voltage is derived for the individual channels, so that when all the channel signals disappear the signalling voltage source is cut off, Fig. 2 (not shown).
