Abstract
In a telecommunications switching system, a thick film digital span conversion circuit is connected between a digital span and a switching network of the switching system. The circuit converts data, which is encoded for digital span use, to TTL logic coding for use by the switching network. The telecommunications switching system also provides for duplicated data transmission through the switching network. Duplicated conversion circuits are employed in an active/standby configuration under CPU control. The present circuit is relatively small in size and has minimal power consumption.
