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).
