标准编号：ISO 9543:1989

中文名称：信息处理系统.系统之间信息的互换.DTE/DCE接口的同步变换信号的质量

英文名称：Information processing systems — Information exchange between systems — Synchronous transmission signal quality at DTE/DCE interfaces

发布日期：1989-04

标准范围

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处串行数据传输的质量要求，符合CCITT建议V.24（电话网络）、X.24（数据网络），如相应CCITT建议的DCE中所规定。根据交换电路的类型，考虑信号质量的性能类别的需要。

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.
