| Abstract: | The service system in disital microwave system which was used on radio transnitting line is discuased. The 3 voice-channels service system was made, which was better than the single voice channel one. The SC filters with high integration are used to construct the hish order dividing channel filters. In last, the constitution of disital service system, frame structure of 704 kb/s multiplexed frame and implementation scheme are given. |
