ABSTRACT:
A building entrance telephone terminal enclosure is provided having a bottom wall with a plurality of openings formed therein for entry of cables into the enclosure. The bottom wall is formed of a pair of plates which mate in meshing engagement along a line running through the centerlines of the openings such that a cable and the components to which it is connected may be installed into the enclosure without removing the components from the cable. The enclosure structure comprises a door which is interchangeable from a left opening to a right opening configuration, and a readily removable, and installable, panel for mounting the components in the enclosure.
