Abstract
Abstract An improved telephone building entrance terminal for use with subscriber-owned equipment. The terminal includes a partition housing including a splice chamber for reception of incoming cable pairs and a second chamber accommodating protector modules and a connector block. Separate covers are hingedly mounted to overlie the splice chamber and the protector and connector chambers. The covers are so arranged that movement of one cover to closed position serves to provide locking means for the other cover whereby only a single padlock is required to prevent unauthorized access to the interior of the housing.
