Design Of Telcom/Datacom Analyzer

The Telecom/Datacom is the cross combination of the communication technique and the computer network technique, it promotes the world to get into the information age accompany with the booming development of information industry, nowadays has become the important technique foundation of the network information techniquedevelopment.The data must be transmitted correctly, therefore, before being brought into service, test and optimization of the transmission loop and network must be taken.The Telecom/Datacom analyzer combines Telecom test and Datacom test together, it can be used in the telecom/datacom communication networks at the rate of 50bit/s～2Mbit/S. It can carry out transmission capability test, function test, electrical parameter test and CAS monitor. When the military and public communication network is being brought into service, and the communication equipment is being designed, produced, installed, maintenance tested, the analyzer is the ideal test instrument.The design technology of the Telecom/Datacom analyzer is mainly discusses in this paper. Firstly, the basic principle, the concept, the key technology and the overall scheme of Telecom/Datacom analyzer is introduced. Then the design of controlling circuit, PCM30/32 system, transmitting/receiving circuit, 2Mb/s Mux, 2Mb/s Demux, error testing and Datacom test circuit are explicated. It introduces the Telecom/Datacom performance test, provides measurement methods and test results of main technical specifications. It explicates the typical use of the Telecom/Datacom analyzer. Finally, it gives some design experiences. The Telecom/Datacom analyzer fills the domestic vacancy, and its performance and specifications reach domestic leading level and oversea advanced level of this field.
