Intended primarily for use in digital subscriber voice/data telephone systems, these devices can also be used in remote data acquisition and control systems. These devices utilize a 256 kilobaud modified differential phase shift keying burst modulation technique for transmission to minimize RFI/ EMI and crosstalk. Simultaneous power distribution and duplex data communication can be obtained using a single twisted–pair wire.
