GB/T 3384-1982 in English

《GB/T 3384-1982模拟载波通信系统网路接口参数》由339-2（工业和信息化部（通信））归口，主管部门为工业和信息化部（通信）。
本标准适用于各种容量及各种传输媒质包括明线、对称电缆、同轴电缆、海底电缆的载波系统以及微波接力与卫星通信系统的载波终端设备等在通信网路中进行音频及各级基础群的相互转接。这种转接都是通过载波终端设备进行的。

Scope

This standard is applicable to carrier systems of various capacities and various transmission media including open wire, symmetrical cable, coaxial cable and submarine cable, as well as carrier terminal equipment of microwave relay and satellite communication systems, etc. group transfers. This transfer is carried out through the carrier terminal equipment. This standard specifies the interface parameters between the microwave relay system and its carrier terminal equipment at the line point. Therefore, the wireless system and the wired system can be connected through the carrier terminal equipment. This standard specifies the interface connection parameters on each interface point, so that the wired system and the wired system and the wireless system can be comprehensively utilized conveniently. This standard specifies the interface parameters for non-telephone service signals entering audio and basic groups at all levels. This standard applies to the establishment of new systems and the technical transformation of old systems.
