  • Page 14: Composition And Principle

    2.3.2 System Principle N number of E1 signals, digital service, 9600bps system net control and 9600bps data relays multiplexed in a multiplexer to a specific microwave frame code. After QPSK modulation, the system sends the transmission to the ODU through an IF cable. It enter the ODU IF upstream balance circuit, upconverter, power amplifier, filter,...
  • Page 15 This frame signal is then processed through demultiplexer to recover the N number of E1 signal and other service signal. The monitor unit of the equipment is controlled by the CPU (central processing unit) to function as: monitoring, controlling, dispatching, alarming, processing and signaling etc.
