Feature Specification
DSL Specifications
ADSL Specifications
●
ST-Microelectronics 20190 Chipset
●
Supports ADSL over basic telephone service with Annex A and Annex B ITU G. 992.1 (ADSL), G.992.3
(ADSL2), and G.992.5 (ADSL2+)
●
G.994.1 ITU G.hs
●
Supports for Reach-extended ADSL2 (G.922.3) Annex L for increased performance on loop lengths greater
than 16,000 feet from Central Office
●
Complies with T1.413 ANSI ADSL DMT issue 2
●
DSL Forum TR-067
●
The chipset does not provide interoperability with carrierless amplitude modulation/phase modulation (CAP)-
based ADSL lines
●
ADSL (G.992.1) provides downstream data rates of up to 8 Mbps and upstream data rates of up to 0.8 Mbps
●
ADSL2 provides higher downstream rates of up to 12 Mbps and upstream data rates of up to 1 Mbps
●
The ADSL2+ standard (G.992.5) increases the downstream data rates of up to 24 Mbps and upstream data
rates of up to 1.5 Mbps
