Low-Power, High-Density, Full-Rate G.lite Solution

The Conexant AccessRunner™ Central Office ADSL modem device set offers standards compliant, full-rate and G.lite functionality with extended reach as a high-density, low-power solution. The device set is fully compliant with ANSI T1.413 Issue 2, ITU G.992.1 (G.DMT), and ITU G.992.2 (G.lite) standards. It supports a downstream data rate of up to 8 Mbps (full rate)/1.5 Mbps (G.lite) and an upstream data rate of 1 Mbps (full rate)/512 Kbps (G.lite). AccessRunner is designed for multiport solutions and works in conjunction with the existing microprocessor on a linecard. Power consumption is only 790mW per port (excluding the line driver). Each port occupies less than two square inches of board space, including the datapump, AFE, line driver, hybrid, transformer, and line protection circuitry.
