标准摘要
[中文适用范围]： 规定了同步传输数据终端设备和数据电路终端设备之间接口串行数据传输的质量要求，符合相应相应 DCE 中规定的 CCITT 建议 V.24（电话网络）、X.24（数据网络） CCITT-建议。 考虑到根据交换电路的类型具有信号质量性能组的需要。 [外文原描述]： Prescribes quality requirements for serial data transmission at the interface between synchronous transmission Data Terminal Equipment and Data Circuit-terminating Equipment in conformance with the CCITT Recommendations V.24 (telephone networks), X.24 (data networks) as specified in DCEs of the corresponding CCITT-Recommendations. Takes into account the need to have performance cotegories of signal quality depending on the type of interchange circuits.
