INTRODUCTION
The Rockwell R96FT is a synchronous serial 9600 bps
modem designed for multipoint and networking
applications. The R96FT allows full-duplex operation over
4-wire dedicated unconditioned lines. or half-duplex
operation over the general switched telephone network.
Proprietary fast train configurations provide training times
of 23 ms for V.29FT/9600/7200/4800, 22 ms for
V.27FT/4800. and 30 ms for V.27FT/2400. A 2400/4800
bps Gearshift configuration provides a training time of 10
ms. For applications requiring operation with international
standards, fallback configurations compatible with CCITT
recommendations V.29 and V.27 bis/ter are provided. A
300 bps FSK configuration, compatible with CCITT V.21
Channel 2, is also provided.
The small size and low power consumption of the R96FT
offer the user flexibility in formulating a 9600 bps modem
design customized for specific packaging and functional
requirements.
This data sheet corresponds to assembly number
TR96D400-061 and subsequent revisions.
