Patent ID: 6980634

Claim:
A telephone circuit controller apparatus comprising: a) a plurality of extension connector ports each selectively connected to a respective communication device; b) a plurality of relay switches, each relay switch having first, second and third terminals and a toggle movable between a first position connecting said first terminal to said second terminal and a second position connecting said first terminal to said third terminal, said first terminal of each said plurality of relay switches being connected to a respective one of said plurality of extension connector ports; and c) a processor connected to an outside telephone line wherein entry of a predetermined command code on one of the communication devices by a user causes said processor to move selective ones of said toggles from said first position to said second position thereby preventing use of the communication device connected to said selective ones of said toggles through a respective one of said plurality of extension connector ports; d) a plurality of tone detector modules, each of said plurality of tone detector modules being connected between said processor and said second and third terminals of a respective one of said plurality of relay switches, said plurality of tone detector modules generating a command signal controlling said processor to connect a respective extension to the outside telephone line when a voltage detected thereby is equivalent to a predetermined voltage; and e) a plurality of tone location identifiers, each of said plurality of tone location identifiers being connected between said processor and a respective one of said plurality of tone detector modules, said plurality of tone location identifiers being activated upon receipt of a control signal from said respective tone detector module for generating a unique signal by which said processor distinguishes said plurality of extension connector ports.
