GB/T 4110-1983
ActivePulse code modulation communication system hierarchy
脉冲编码调制通信系统系列
Application Summary AI generated
This standard specifies the hierarchical structure and bit rates for pulse code modulation (PCM) communication systems, defining the multiplexing levels from primary to higher-order groups. It is applied in the design, manufacturing, and testing of digital telecommunication equipment and networks in China, particularly for time-division multiplexed voice transmission over cable and microwave links. The standard ensures interoperability between different PCM systems used in public telephone networks and dedicated communication links.
