The Cisco 870 Series Integrated Services Routers extend the high-performance Cisco Integrated Services Router capabilities of running secure concurrent services, including firewall, VPNs, and WLANs, at broadband speeds to small offices. Easy deployment and centralized management features enable the Cisco 870 Series to be deployed in small office or teleworker sites as part of an enterprise network, by small to medium business customers for secure WAN and WLAN connectivity, or used by service providers to offer business-class broadband and WLAN services.
Product Overview
Cisco 870 Series of integrated services routers are fixed-configuration routers that support multiple types of DSL technologies, broadband cable, and Metro Ethernet connections in small offices (Figures 1 and 2). They provide the performance needed to run concurrent services, including firewall, intrusion prevention, and encryption for VPNs; optional 802.11b/g for WLAN networking; and quality of service (QoS) features for optimizing voice and video applications. In addition, the Cisco Router and Security Device Manager (SDM) Web-based configuration tool simplifies setup and deployment (Figure 3), and centralized management capabilities give network managers visibility and control of the network configurations at the remote site.
Cisco 870 Series integrated services routers offer:
? High performance for broadband access in small offices
? Enhanced security, including:
? Stateful Inspection Firewall
? IP Security (IPSec) VPNs (Triple Data Encryption Standard [3DES] or Advanced Encryption Standard [AES])
? Intrusion prevention system (IPS)
? Antivirus support through Network Admission Control (NAC) and enforcement of secure access policies
? 4-port 10/100 managed switch with VLAN support
? Secure WLAN 802.11b/g option with use of multiple antennas
? Easy setup, deployment, and remote management capabilities through Web-based tools and Cisco IOS® Software
Table 1 lists the routers that currently make up the Cisco 870 Series.

Feature
|
Benefits
|
|
Increased Performance to Run Concurrent Services
|
? The performance in a Cisco 870 Series router allows customers to take advantage of broadband network speeds while running secure, concurrent data, voice, and video services |
|
Enhanced Security
|
? Integrated Stateful Inspection Firewall for network perimeter security, high-speed IPSec 3DES and AES encryption for data privacy over the Internet, IPS, and antivirus support through NAC to enforce security policy in a larger enterprise or service provider network |
|
4-Port 10/100 Mbps Managed Switch
|
? Allows multiple devices to be connected in a small office, with the ability to designate a port as network DMZ
? Optional external PoE adapter for powering IP phones, to avoid individual power supplies or power injectors
? VLANs allow for secure segmentation of network resources |
|
Optional 802.11b/g WLANs with Support for Multiple Antennas
|
? Broadband router with secure WLAN in a single device
? Diversity antennas for optimizing coverage in a small office
? Options for replaceable external antennas, to get wireless coverage in areas away from where the router is located |
|
Cisco SDM and Cisco IOS Software for Remote Management
|
? Using smart wizards and task-based tutorials, Cisco SDM helps resellers and customers quickly and easily deploy, configure, and monitor a Cisco access router without requiring knowledge of the Cisco IOS® Software command-line interface (CLI)
? Dial backup and out-of-band management allow IT managers to remotely manage the router at small office and teleworker sites
? Cisco Configuration Express Service supports factory-loaded configurations for high-volume deployments
? Support for the Cisco Configuration Engine enables plug-and-play installations with centralized configuration management |

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+)
? 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 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.
? 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. |
