ADSL Port One ADSL over POTS port on Cisco 1801. One ADSL over ISDN on Cisco 1802. The Cisco 1801 supports ADSL over POTS standards G.992.1 G.DMT and ANSI T1.413 DMT Issue 2. The Cisco 1802 supports ADSL over ISDN standards ETSI 101-388, U-R2, and G.992.1 G.DMT.
DSL 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+)
  • Supports ADSL over basic telephone service with Annex M (extended upstream bandwidth) G.992.3 (ADSL2) and G.992.5 (ADSL2+) for Cisco 1801 only
  • G.992.1 ITU G.DMT support
  • G.994.1 ITU G.hs negotiation
  • Support for Reach-extended ADSL2 (G.922.3) Annex L
  • 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.

Annex M is supported starting with the special Cisco IOS Software Release 12.4(11)XJ.

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.

ITU G.992.3 Annex M adds capabilities for extended upstream bandwidth above 2.0Mbps. This allows carriers and enterprises to cover applications traditionally served by T1, E1, G.SHDSL without overhauling the transport infrastructure. Exact data rates vary depending on the distance from the DSL access multiplexer (DSLAM), DSLAM type, line card and chipset, and firmware, noise profile, quality of copper, etc. The reach-extended ADSL2 standard (G.992.3) Annex L increases performance on loop lengths greater than 16,000 feet from the Central Office
