Abstract: A network interface device includes a base, a cover and a circuit board secured in the base. The circuit board includes terminations for input and output communication lines. Each pair of input and output communication lines corresponds to a single standard telephone line, a high speed data line or other type of line. The communication line terminations may be implemented as insulation displacement connectors, and the cover may include projections on its inner surface such that closing the cover also closes the insulation displacement connectors on the circuit board. For each communication line, the circuit board may include a subscriber bridge which establishes a breakable connection between the input and output line terminations via traces in the circuit board. In fixed wireless, fiber-to-the-home (FITI) and other similar applications, the circuit board may also include terminations for input and output power lines, and the base and cover may be extended to accommodate an uninterruptible power supply.

Abstract: A high-strength, heat-resistant alloy is provided which comprises, in weight percent, about 0.2 to about 0.75 percent carbon, from about 20.0 to about 30.0 percent chromium, from about 15.0 to about 60.0 percent nickel, up to about 2.0 percent manganese, up to about 2.5 percent silicon, from about 3.0 to about 10.0 tungsten, from about 0.1 to about 1.0 zirconium, with the balance being iron plus incidental impurities.
