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.

Key Features

  • Signaling and Control I/O Capable of Sharing Common Bus Wiring with Other UDLTs.
