Title: Automatic Telecommunication Exchange
IPC: H04Q3/72
Filed: 1968-03-07
Abstract: 1,155,685. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 7 March, 1968 [13 March, 1967], No. 11151/68. Heading H4K. In an exchange system in which subscribers lines are directly connected to inlets of a crossbar switch, at least two outlet levels of the latter are reserved for making loop tests which can differentiate between " calling loop " and " permanent loop " conditions. As shown, the lines lg1-lg16 are connected to respective inlets ent1-ent16 of a two section crossbar multiswitch MS1, MS2 while links ml1-ml8 to the next switching stage extend from outlet levels NH1-NH8 theroef. Outlet levels NH9 - NH11 are reserved for loop testing and they are separated from the link outlet levels by saturable core transformers TR1-TR16 inserted in the inlet multiples. The latter are split between levels NH10 and NH11 to assist in the discrimination between the loop conditions. If the handset of line lg1 say, is on hook, contacts ct1 ct2 are closed so that battery and earth are connected to the unlooped a and b wires while all other contacts of selector SL1 are open. Scanning pulses from EXL applied to primary winding ene of transformer TR1 induce similar pulses in secondary winding ens to indicate that the line is unlooped. If the line is now looped, TR1's core becomes saturated whereby the pulses in ens cease and consequently central control causes the line to be connected through to a free link say ml1 by closing contacts ct5, ct6. At the same time contacts ct1, ct2 open to unsaturate the core but the recommencement of pulses from ens is no longer construed by central control as an indication that the line is free. At the end of the call and assuming that the called party hangs up first, contacts ct5, ct6 are opened while contacts ct3, ct4, ct7 are closed. Consequently battery and earth are connected to the looped a, b wires so that the pulses from ens are again inhibited and a warning tone from howler ton is induced in the line wires. In addition pulses from scanner EXC are now returned to the central control since ct7 is closed whereby a permanent loop condition is recognized. When the handset is replaced, the presence of pulses from both EXL and EXC indicates that the selector may now be fully released viz contacts ct1, ct2 closed and all the other contacts open.
