| Abstract: | The method for improving the interface of the ZDD-12 power line carrier is introduced in this paper. By the improving, the carrier is of a 4W E/M interface, which is able to be connected directly to PCM and exchange equipment. As a result, the voice frequency frame can be omitted; The improved carrier wave machine is simple and reliable in configuration; Its operation and maintenance costs are low. |
