Abstract: A storage container has a bottom panel, an upstanding circumferentially continuous side wall coupled to a perimeter of the bottom panel, and a container interior defined by the bottom panel and side wall. The container also has an open top opening into the container interior and defined at a top edge of the continuous side wall. The container further has a pair of hanger elements disposed opposite one another across the top opening. Each of the pair of hanger elements extends from the top edge of the continuous wall.

Abstract: A pulse form restorer (pulse repeater) which detects that it is not passing pulse bit steam inserts a fixed resistor in series with the constant current cable power supply, and isolation of the faulty unit is accomplished by measurement of the voltage drop through the cable system. In a test mode the near end driver modulates the digital data at a slow alternating rate. A cable fault locator coupled to the power supply output comprises a peak detector, an A/D converter and a numerical display, which convert the change in voltage between data-on and data-off intervals to a number, which by a table look up designates the faulty restorer.
