Information processing systems — Information exchange between systems — Synchronous transmission signal quality at DTE/DCE interfaces
信息处理系统——系统间的信息交换——DTE/DCE接口处的同步传输信号质量
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.
