The ITW MCO25-60 allows you to protect 25 analog central office lines via a RJ-21X (Amphenol) connector (male in, female out). Therefore, the cable coming from the phone company side that plugs into the LINE side of the MCO25 needs to have a female end. The unit features auto-resetting technology, PTC resistors open when a surge occurs, but once the surge has passed, they close again!
