Abstract: This invention discloses a network termination module which comprises a base structure having a means for grounding. Mounted on and above the base structure are a pair of insulation displacement terminals, a telephone jack and subscriber terminals. The insulation displacement terminals are electrically connected to the telephone jack. The network termination module also includes an openable cover which, in its closed position, establishes electrical connection between the insulation displacement terminals and the subscriber terminals, and, in its open position, breaks the electrical connection between the insulation displacement terminals and the subscriber terminals. The cover, in its closed position, also closes off access to the jack and to the subscriber terminals. Disposed within the base structure is a protector element which is electrically connected to the insulation displacement terminals. The protector element is also electrically connected to the means for grounding.
