The "Born Again UDS 202T" Modem

Telenetics introduces the latest addition to the family of industrial grade, temperature hardened Modems, Model MOT202T. This 0-1800 bps leased telecom line or private wire modem is a pin-for-pin, form, fit and function replacement for Motorola Model RM16M. 

The MOT202T is a direct replacement for the very popular 30-year-old design that Motorola acquired through the purchase of Universal Data Systems and is purported to be the largest installed base of 1800 bps modems that is multidrop and in demand.
