ActiveSpecifications of TDM equipment operating on an analog telephone-type circuit for telegraph and lower-speed data
在模拟电话电路上开放电报及低速数据的时分复用设备技术要求
Application Summary AI generated
This standard specifies the technical requirements for time-division multiplexing (TDM) equipment that enables the transmission of telegraph signals and low-speed data over analog telephone-type circuits. It is applied in telecommunications networks where multiple lower-speed data channels (such as those used for telex or early data modems) are combined onto a single analog voice-frequency channel for efficient transmission. The standard ensures interoperability and performance consistency in legacy telecommunication systems, particularly in public switched telephone networks (PSTN) and dedicated leased-line applications.
