1.0 GENERAL DESCRIPTION

The STLC1510 is a high-speed modem chip that provides the digital portion of a G.992.2 DSL access at a

Central Office (CO) site. It provides downstream and

upstream data transport between an ATM byte

stream and an analog front-end chip using Discrete

Multi-Tone (DMT) Modulation.

The STLC1510 is compliant with ITU-T G.992.2

(G.Lite), G.996.1 (G.Test), G.994.1 (G.Handshake),

G.997.1 (G.Ploam).
