Title: Digital transmission system for pair cable
Inventor: KAMEYAMA SHIGEJI
IPC: H04L25/49
Filed: 1988-01-19
Abstract: PURPOSE:To correctly decode a multivalue code by switching a connection between a connecting terminal with a transmission line and a receiver circuit to a positive phase or a negative phase according to the polarity information of a direct current in the connecting terminal of the transmission line. CONSTITUTION:When, by a connection in a pair cable 1, connecting terminals 4 and 7 are connected and connecting terminals 5 and 6 are connected, a current i2 is made to flow through a photodiode D3, a resistance R and a D4 to a switching circuit 31 by the voltage of a DC voltage source DC 21. In such a condition, a pulse waveform sent from a line driving circuit LDV 22 arrives at the connecting terminals 6 and 7 while the polarity is inverted, positive and negative polarity information is reinverted by the switching circuit 31, and it is inputted to a receiving circuit REC 32. Namely, a pulse polarity sent from the LDV 22 is normally reset and inputted to the REC 32. Thus, even when identifications at a chip side and a ring side in the pair cable are confused and the connection confusion is generated, a reception can be executed in maintaining the polarity of the LDV 22 output.
