ISDN是一种数字通信网络，它提供了一种集成的服务，包括语音、数据和视频。ISDN基本接入接口是连接用户设备和ISDN网络的接口。ISO/IEC 8877:1992标准规定了ISDN基本接入接口的连接器和引用点S和T之间的联系分配。该标准的目的是确保不同厂家生产的设备可以互相连接，并且可以在ISDN网络上进行通信。

该标准规定了ISDN基本接入接口的连接器和引用点S和T之间的联系分配。连接器是用于连接用户设备和ISDN网络的物理接口。引用点S和T是ISDN基本接入接口的两个端点，它们之间的联系分配规定了数据和信令的传输方式。该标准规定了连接器和引用点S和T之间的联系分配的电气和机械特性，包括引脚分配、信号电平和传输速率等。

ISO/IEC 8877:1992标准适用于ISDN基本接入接口的所有类型，包括欧洲、北美和日本的接口。该标准的实施可以促进不同厂家生产的设备之间的互操作性，从而提高ISDN网络的可靠性和灵活性。
