| Abstract: | Using technologies of Time Division Multiplex (TDM) and Pulse Code Modulation(PCM),a system meeting requirement of long-distance voice transmission for underground mine is designed that can be used separately or for the case of integrative transmission,or be embedded into other systems for application.The system consists of 2 parts-central office(CO)part and remote terminal(RT)part.Emphasis of discussion is CO part. |
