METHOD FOR COMPENSATING CURRENT VARIABLES OF A SUBSCRIBER CIRCUIT WHICH HAVE BEEN MODIFIED BY DISTURBANCE VARIABLES

摘要

The invention relates to a compensation and current measurement method for a subscriber circuit of a digital telephone exchange said circuit consisting of a high-threshold part (HV) and a low-threshold part (NV). The inventive process is integrated into the low-threshold part. According to the invention, a disturbance variable which has been determined in advance and stored in the low-threshold part (NV) with a reversed sign is added to the currents which are measured e.g. for adjusting the power supply or the reliability performance of the subscriber circuit. The current can then be measured based on current values which have already been corrected.
