Special Features:

Adapter shall be a filter/surge suppressor to perform emi and surge protection on telephone signals. The filter/suppressor shall operate with normal switched telephone signal levels. It must pass the ac ring voltage of approximately 170 vac as well as audio up to 4khz. There shall be 4 pins on each filter. All 4 pins shall be filtered and protected for surge. Surge protection shall be shunted to case ground. Current rating - load current 0.5 amperes per pin; operating voltage - 200 vac; dc resistance - 0.2 ohms or less. The input end of the housing shall have a rj-11 socket telephone connector and a mounting flange. The flange shall have two 4-40 screw inserts. The output end shall have a rj-11 connector. The pins shall be wired pin to pin

Properties:

An adapter with electrical contacts which provides facilities for joining two or more electrical connectors, whose design or function will not normally warrant their junction. it is not designed for permanent attachment to a cable, cord, coaxial line, or wire. the physical shape of an electrical connector should not be the determining factor of its name. tee, angle, straight, and y-shaped adapters are all adapter, connector. excludes adapter, connector to lampbase; adapter, lampholder to connector; adapter (1), cable clamp to connector; and adapter, lampholder. for items designed as a mechanical connection between an electrical conduit and an electrical connector, see adapter (1), electrical conduit.
