Abstract: An integrated access device is automatically configured to conduct packetized voice and data communications between a customer's voice/data equipment and a digital communications switch. For this purpose, the IAD's communication control processor is programmed to perform an automated analysis of the digital communications link and thereby identify communication interface circuits such as DSLAM and voice gateway units, that have been installed by the service provider. It then automatically configures the communication parameters of the IAD for communication compatibility with the communication interface circuits.

Abstract: A method for repairing metal pipe with dents includes steps of a) holding the pipe with first and second ends in position; b) dragging the mandrel through the pipe; and c) pushing out the dents from inside to an original level of the surface of the pipe. The cross-section of the mandrel has a substantially same cross-section of the hollow space of a undamaged pipe, and the outer surface of the major portion of the mandrel fits tightly to the inside of the undamaged pipe. The step of holding the pipe includes steps of a) guiding the pipe into a locking position; b) stopping the pipe along the direction of the axis of the pipe; and c) stopping the pipe along the perpendicular direction of the axis of the pipe.

Abstract: The invention provides a dedent system, which comprises a bullet shank and a cable shank. The bullet shank comprises a male shank portion and a first latching portion. The first latching portion comprises a first contacting surface and a locking hole, and the locking hole is tilted such that an opening on the first contacting surface is closer to the male shank portion than a portion of the locking hole which is farther from the first contacting surface. The cable shank comprises a female shank portion and a second latching portion. The second latching portion comprises a second contacting surface and a locking bump. The female shank is connected to a cable, and the locking bump is tilted such that a portion of the locking bump on the first contacting surface is farther to the female shank portion than the a tip portion of the locking bump.

Abstract: A system for repairing a pipe damaged with dents includes a pipe holding device, a mandrel, a cable, and a winch. The pipe holding device is for holding the pipe in position. The mandrel, with a cross section and size adapted to be pulled through the interior of the pipe, has a first edge, a second edge, and a side surface. The cable has first and second ends, and the first end is detachably attached to the first edge of the mandrel. The winch is connected to the second end of the cable for winding up the cable. The mandrel is pulled by the winch with the cable and travels through the pipe to push out from inside and remove the dents on the surface of the pipe.
