This unit is designed to increase the line voltage of an analog telephone line thus allowing multiple analog telephpones or answering machines to be connected to a single analog telephone line (or a less powerful ATA unit via the internet.) Especially helpful to ring one or more vintage analog telephones/answering machines. The unit will also re-shape the ring circuit to the correct (original) format for analog telephone devices. These commercial units are usually priced at around $125.
