    摘要： A system, method, and computer readable medium for a metallic test method in a digital subscriber line system in which a subscriber's voice service has been switched from plain old telephony service to an inband digital subscriber line data stream characterized in that a direct current loop current used for plain old telephony service is replicated for testing, comprising, providing a sealing line current to a transmission line via a digital subscriber line device serving the subscriber and supervising the provided sealing line current between the digital subscriber line device and a subscriber's premises for determining a connectivity therebetween.

    摘要： To reduce the distortion of digital data due to on/off switching of the ringing of a Plain Old Telephone Service (POTS) signal (RINGING1, RINGING2) transmitted simultaneously with the digital data over a single line (LINE), the telephone ringing signal generator (POTS-RING GENERATOR 1, POTS RING GENERATOR 2) produces a digital data friendly ringing signal (RINGING1, RINGING2). The telephone ringing signal generator (POTS-RING GENERATOR 1, POTS RING GENERATOR 2) thereto applies a transient smoothening window (WINDOW1, WINDOW2) to a sine or cosine shaped signal (SINE1, SINE2).

    摘要翻译： 为了减少由于通过单线（LINE）与数字数据同时传输的普通老式电话服务（POING），RINGING2的振铃的开/关切换来减少数字数据的失真，电话振铃信号发生器 （POTS-RING GENERATOR 1，POTS RING GENERATOR 2）产生数字数据友好振铃信号（RINGING1，RINGING2）。 电话振铃信号发生器（POTS-RING GENERATOR 1，POTS RING GENERATOR 2）将瞬态平滑窗口（WINDOW1，WINDOW2）应用于正弦或余弦信号（SINE1，SINE2）。
