本技术要求（TRQ）文件定义了三种类型的网络设备设施线路共享分配器。TRQ中未描述设备的物理环境。本TRQ描述了三个网络设备设施线路共享分配器的电气特性，其功能是充分减少DSL信号对线路卡的影响，并允许传统普通电话服务（POTS）通信。这些要求支持几种类型的DSL信号传输。本TRQ中还包括测试方法的说明，以确定符合性，并将这些要求意图的模糊性降至最低

This technical requirements (TRQ) document defines three types of network equipment facility line sharing splitters. The physical environment of the device is not described in the TRQ. This TRQ describe the electrical characteristics of three network equipment facility line sharing splitters function to sufficiently reduce the DSL signal impact on the line card, and permit legacy plain ordinary telephone service (POTS) communication. These requirements support several types of DSL signal transmission. Also included in this TRQ are descriptions of test methods to ascertain compliance and minimize ambiguity of the intent of these requirements
