    • A digital wideband node (DWN) (28, 48) is coupled to a remote terminal (RT) (22, 42) that in turn is coupled to a subscriber's telephone line (26, 46). The DWN (28, 48) is configured to (1) pass a subscriber's telephone number signal directly to the RT (22, 42) whereupon a test path (25, 45) is formed with the subscriber's telephone line (26, 46), (2) pass POTS test signals directly to the RT (22, 42) for testing the subscriber's telephone line (26, 46) via the test path (25, 45) and (3) process wideband test control signals into wideband test signals which are conveyed to the RT (22, 42) for wideband testing of the subscriber's telephone line (26, 46) via the test path (25, 45).
    • 数字宽带节点(DW)(28,48)耦合到远程终端(RT)(22,42),远程终端(22,42)又耦合到用户的电话线路(26,46)。 DWN(28,48)被配置为(1)将用户的电话号码信号直接传送到RT(22,42),由此与订户的电话线路(26,46)形成测试路径(25,45), (2)将POTS测试信号直接通过RT(22,42),经由测试路径(25,45)测试用户的电话线路(26,46),以及(3)将宽带测试控制信号处理成宽带测试信号, 被传送到RT(22,42),用于通过测试路径(25,45)对用户的电话线路(26,46)进行宽带测试。
