摘要： A method of diagnosing a transmission loop in an Internet protocol television (IPTV) network includes configuring the loop as an open loop and performing a single-ended loop test (SELT), configuring the loop as a terminated-loop and performing another SELT, subtracting a trace of the first SELT from a trace of the second SELT, and determining the length of the loop from the result. A service assurance system in an IPTV network includes a test module and a DSLAM coupled to a residential gateway by a transmission loop. The test module operates to determine that a fault condition on the IPTV network is caused by a fault in the loop, direct the DSLAM to perform an open loop SELT and a terminated-loop SELT on the loop, receive the results of the SELTs, and determine a location of a tap on the loop based upon the results.

摘要： A dual-mode broadband modem operative to operate in a service mode and a surveillance mode is disclosed. Generally, the dual-mode broadband modem comprises a primary communication device; a secondary communication device; a central processing unit in communication with the primary and secondary communication devices; and a memory unit in communication with the central processing unit. In the service mode, the primary communication device communicates with a broadband service provider and the central processing unit stores historical information regarding performance of the primary communication device in the memory unit. If an interruption in broadband service is detected, or the performance of the primary communication device falls below a predetermined threshold, the dual-mode broadband modem switches to surveillance mode and the secondary communication device is activated. The secondary communication device communicates with the broadband service provider to send at least a portion of the historical information regarding performance of the primary communication device to the broadband service provider for processing to determine a source of the interruption in broadband service or a source of the decreased performance of the primary communication device.
