Abstract
In a telecommunications switching system, a thick film digital span transmission circuit is connected between a digital span and a switching network of the switching system. The circuit converts unipolar switching network data to bipolar data for digital span use. The present circuit is relatively small in size and has minimal power consumption. This circuit also provides for attenuating and shaping the pulses transmitted to the digital span.
