Title: Telephone system loop current detector - comprises three coil inductance with centre coil voltage drop changed from high to low to distinguish between no current and normal current
Inventor: DANIELS DOUGLAS LEE
IPC: H04Q3/00
Filed: 1976-03-24
Abstract: A loop current detector for telephone transmission lines uses an inductance with three coils, the centre one of which is switched from a low inductance valve to the saturated state by the presence of a loop current. The outer two coils of an inductance with a laminated core are coupled into the twin transmission cable of a line between the exchange and a subscriber station. When the receiver relays are closed a d.c. current, provided by a supply, flows in the loop. An oscillator provides a 20kHz signal over a resistance to the centre coil of the inductance. When zero loop current flows the voltage drop in the centre coil is high and when the current is high the voltage drops is low. A switching stage responds to the two conditions.
