Abstract: A remote test unit (RTU) and method of operation are provided for utilizes the ability of an access matrix ability to route signals. The RTU can emulate a central Digital Subscriber Line Modem (DSLM-C) for testing customer premises equipment containing a remote Digital Subscriber Line Modem (DSLM-R). The RTU can also emulate a DSLM-R for testing central offices equipment including a digital subscriber line access multiplexer (DSLAM) containing a DSLM-C. The RTU can also emulate a concentrator connected to the DSLAM, a router connected to the concentrator, an Internet service provider (ISP) connected to the router, and a web site connected to the ISP over the Internet. The RTU can further test, using emulation, ISO/OSI layers defined in the ISO/OSI reference model which are connected to the DSLAM.

Abstract translation: 提供远程测试单元（RTU）和操作方法，以利用访问矩阵能力来路由信号的能力。 RTU可以模拟中央数字用户线路调制解调器（DSLM-C），用于测试包含远程数字用户线路调制解调器（DSLM-R）的客户驻地设备。 RTU还可以模拟DSLM-R，用于测试中心局设备，包括包含DSLM-C的数字用户线路接入复用器（DSLAM）。 RTU还可以模拟连接到DSLAM的集线器，连接到集中器的路由器，连接到路由器的因特网服务提供商（ISP）以及通过因特网连接到ISP的网站。 RTU可以使用仿真进一步测试连接到DSLAM的ISO / OSI参考模型中定义的ISO / OSI层。
