DSL specifications
●
ST-Microelectronics 20190 chipset
●
Supports ADSL over PORS (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
●
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
●
Annex A and Annex B are supported starting with Cisco IOS Software Release
12.4(4)T.
●
The ADSL2 standard (ITU G.992.3) adds new features and functions targeted at
improving ADSL performance and interoperability. In addition, the standard adds
support for new applications, services, and deployment scenarios. Among the
changes are improvements in data rate and reach performance, rate adaptation,
improved diagnostics, and power enhancements. The conventional ADSL standard
(ITU G.992.1) provides downstream data rates of up to 8 Mbps and upstream data
rates of up to 0.8 Mbps, and ADSL2 provides higher downstream rates of up to 12
Mbps and upstream data rates of up to 1 Mbps.
●
The ADSL2+ standard (ITU G.992.5) doubles the bandwidth used for downstream
data transmission, effectively doubling the maximum downstream data rates and
achieving downstream data rates of up to 24 Mbps and upstream data rates of up to
1.5 Mbps.
Wireless Specifications
Data rates supported 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54 Mbps
