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语音、数据和视频通信服务。PISN通常由私有交换机、路由器和其他通信设备组成,可以提供高质量的通信服务和更好的安全性。

ISO/IEC 14843:2003标准定义了PISN之间的呼叫提供补充服务的互换信令协议。呼叫提供补充服务是指在呼叫过程中提供的一些额外功能,例如呼叫转移、呼叫等待、呼叫保持和呼叫补充服务。这些功能可以提高通信的效率和便利性。

ISO/IEC 14843:2003标准规定了PISN之间呼叫提供补充服务的互换信令协议的具体内容。其中,呼叫转移是指在呼叫过程中将呼叫转移到另一个终端;呼叫等待是指在呼叫过程中等待另一个呼叫;呼叫保持是指在呼叫过程中将呼叫暂停,以便进行其他操作;呼叫补充服务是指在呼叫过程中提供其他的服务,例如呼叫转接、呼叫等待和呼叫保持。

ISO/IEC 14843:2003标准的实现可以提高PISN之间的通信效率和便利性,同时也可以提高通信的安全性。该标准的实现可以帮助组织更好地管理其通信网络,提高通信的质量和效率。
