Feature Description

Console port RJ-45


External power supply Universal 100 to 240V AC

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+)

● 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)-basedADSL 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.

Maximum transmit power Note: Maximum power setting is subject to change by channel and by region, depending on regulations.
