标准摘要
[中文适用范围]： 该国际标准规定了在专用综合业务网络（PISN）内连接在一起的专用综合业务网络交换机（PINX）之间支持时钟同步（SYNC-SIG）的信令协议。 该协议支持使用每个 PINX 可用的不同时钟源来同步 PISN。 该协议基于国际标准 ISO/IEC 11573 附录 F 中描述的同步方法。 该国际标准适用于可以互连形成 PISN 的 PINX。 [外文原描述]： This International Standard specifies the signalling protocol for the support of clock synchronization (SYNC-SIG) between Private Integrated Services Network Exchanges (PINXs) connected together within a Private Integrated Services Network (PISN). This protocol supports the synchronization of a PISN using the different sources of clocks available to each PINX. The protocol is based on the method of synchronization described in annex F of the International Standard ISO/IEC 11573. This International Standard is applicable to PINXs which tan be interconnected to form a PISN.
