电力线载波通信是近年来迅速发展的一门通信技术,传统载波机的语音传真接口为模拟口,随着全数字电力线载波机的研制,充分发挥数字技术的优点提高了通信的质量。本文主要讨论在数字电力线载波机上采用存储转发进行传真通信的技术,研究了传真接口的实现方法。 Power line carrier communication is a rapidly developing communication technology in recent years. The traditional fax machine’s voice fax interface is a simulation port. With the development of all-digital power line carrier, the advantages of digital technology are fully utilized to improve communication quality. This paper mainly discusses the technology of using store-and-forward fax communication in digital power line carrier, and studies the implementation of fax interface.
