Abstract
A telephone line demarcation unit separates the telephone company's property and wiring from those of the user and provides security for the telephone line connections and connectors. Compartments in the unit provide easy access for the user and further provides a selection of different types of connections or equipment that can be utilized. The telephone company terminals and test boards are separately compartmented so that the compartments can be separately sealed with seals to discourage tampering and provide evidence of tampering, and yet the user's portion of the interface box demarcation unit can be easily accessed for connecting a variety of telephone equipment.
