私有综合服务网络（PISN）是一种专用的通信网络，用于在组织内部提供各种通信服务。PISN可以提供语音、数据和视频通信服务，同时还可以提供各种补充服务，如呼叫等待、呼叫转移、呼叫保持等。这些补充服务可以提高通信的效率和可靠性，使用户更加方便地使用通信服务。

ISO/IEC 13866:1995标准规定了PISN中的呼叫完成补充服务的功能模型和信息流。呼叫完成补充服务是指在呼叫过程中提供的一系列服务，包括呼叫等待、呼叫转移、呼叫保持、呼叫重试等。这些服务可以帮助用户更好地管理通信，提高通信的效率和可靠性。

ISO/IEC 13866:1995标准规定了呼叫完成补充服务的功能模型，包括呼叫等待、呼叫转移、呼叫保持、呼叫重试等。这些功能模型可以帮助用户更好地理解呼叫完成补充服务的工作原理，从而更好地使用这些服务。

此外，ISO/IEC 13866:1995标准还规定了呼叫完成补充服务的信息流。信息流是指在呼叫过程中传输的各种信息，包括呼叫请求、呼叫确认、呼叫等待、呼叫转移、呼叫保持、呼叫重试等。这些信息流可以帮助用户更好地了解呼叫完成补充服务的工作过程，从而更好地使用这些服务。

总之，ISO/IEC 13866:1995标准规定了PISN中呼叫完成补充服务的功能模型和信息流，为用户提供了更好的通信服务。该标准适用于使用PISN的电信和信息技术领域。
