lows to get a T1.413 Issue 2 compliant solution.

The STLC60134S analog front end handles 2

transmission channels on a balanced 2 wire inter-

connection; a 16 to 640Kbit/s upstream channel

and a 1.536 to 8.192Mbit/s downstream channel.

A 256 carrier DMT coding (frequency spacing

4.3125kHz) transforms the downstream channel

to a 1MHz bandwidth analog signal (tones 32-

255) and the upstream channel (tones 8-31) to a

100kHz bandwidth signal on the line.

This asymmetrical data transmission system uses

high resolution, high speed analog to digital and

digital to analog conversion and high order ana-

log filtering to reduce the echo and noise in both
