The Model 1035 high speed short range modem supports synchronous data rates of 32, 56 and 64 Kbps, and distances up to 6 miles/9.7Km (19 AWG at 32 kbps) over two unconditioned twisted pair. Transmit clock options are internal, external and receive recover clock.

Power from a 7.5V wall-mount transformer, the Model 1035 incorporates two V.54 test modes and a V.52 BER test pattern generator/detector. Five easy-to-read LED indicators monitor power, transmit data, carrier detect, test mode and test pattern. For protection against ground loops and transient surges, the Model 1035 incorporates both isolation transformers and Silicon Avalanche Diode surge suppressors. The Model 1035 is available in an RS-232/V.24 version and a CCITT V.35/ (RS-530) version, both supported on a DB-25 connector. Twisted pair connection are made using RJ-11 or RJ-45.
