Title: Terminal network controller
Inventor: YAMASHITA KUNIHIKO
IPC: H04M11/00
Filed: 1992-10-19
Abstract: PURPOSE:To unnecessitate insulation between a line and to surely attain the detection of polarity inversion with simple circuit constitution by using a full wave rectifying type connection means for connection between the line. CONSTITUTION:The full wave rectifying type connection means 2 is provided at the input terminal of a terminal network controller 1 and connected to the telephone line by terminals L1 and LA2. Before polarity inversion, L2 is set to be-48V with L1 as a reference and an L level is outputted to the output point D of a polarity detection 3 to be stored in a polarity inversion means 5. When the polarity of the line is inverted, a line voltage detection means 4 outputs a pulse like signal to a point B and the polarity detection means 3 changes the signal into a level H. A discrimination means 5 checks a point D to judge that polarity is inverted when the level of the point D is different from the stored level. At the time of a hit, a storage state does not change at the point D and at the time of a disconnection, the output of the line voltage detection means 4 is kept at the level L so that polarity is not judged to be inverted in both cases. Thus, polarity inversion is surely detected without malfunction with a simple circuit.
