Маршрутизатор Cisco 871 для небольшого офиса

Интегрированный маршрутизатор (Integrated Serivce Router, ISR) компании Cisco. Снят с производства, но может ещё встречаться сисадминам.

Компания Cisco рассматривает этот маршрутизатор для работы в:

• маленьких офисах и удалённых филиалах;
• сетях малого и среднего бизнеса для обеспечения безопасного Интернет-соединения и построения безопасной беспроводной сети;
• для сервис-провайдеров, предоставляющих широкополосный и беспроводной доступ своим клиентам.

  • 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 (except UK Mask) (extended upstream bandwidth) G.992.3 (ADSL2) and G.992.5 (ADSL2+)
    • G.994.1 ITU G.hs
    • 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 (except UK Mask) is supported starting with the special Cisco IOS Software Release 12.4(11)XJ; and requires the CISCO877-M-K9 or CISCO877W-G-E-M-K9 SKU.
    • 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.
    • Cisco 877-M supports ITU G.992.3 Annex M (except UK Mask), and is optimized for PSD Mask EU-64 M9. 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.
