Patent

CA 2017694

The present invention relates to an interface device between a two-way transmission channel with analog signals and a four-wire input of a digital communication system. Construction of the interface device in 10 V technology as an integrated module is made possible by operating the transformer (U) in the lower frequency range as an attenuator pad and selecting such a transmitting or terminating resistance that all signaling voltages are transformed in a range that can be evaluated in 10 V technology, whereby to suppress higher frequency disturbance signals the signaling voltages are fed via a lowpass filter (TP) to a ringing signal detecfor (RD) or via a selective bandpass filter (BP) to a call charge signal detector (GD).
