DATA SHEET

The ADSL WAN interface cards (WICs) supported on the Cisco 1700/2600/3700 series routers are also supported on the Cisco 1800 (modular), 2800, 3800 series Integrated Services Routers (ISRs). These WICs deliver business class ADSL over basic telephone service or otherwise known as Plain Old Telephone Service (POTS) (through WIC-1ADSL and WIC-1ADSL-DG) and ADSL over ISDN (through WIC-1ADSL-I-DG) services for small and medium-sized businesses to enterprise branch offices (Figure 1). These ADSL WICs, combined with the Cisco 1700/1800/2600/2800/3700/3800 Series routers, enable service providers and resellers to offer additional services by supporting features for business-class security, voice integration, differentiated classes of service, and managed network access with Cisco IOS® Software. These value-added features, along with the manageability and reliability of Cisco IOS technology, provide the mission-critical networking that businesses require.

The single-port ADSL WICs, which fit into any of the WIC, VIC/WIC, HWIC slots on the Cisco 1700/1800/2600/2800/3700/3800 series modular access routers, provides high-speed digital data transmissions between the customer premises equipment (CPE) and a central office (CO). (Figure 1 shows a single WIC to represent all three WICs; all three WICs resemble each other.)

APPLICATIONS OF CISCO ADSL WICS

Business-Class DSL with WAN Backup

The Cisco 1700/1800/2600/2800/3700/3800 series routers offer multiple WAN slots. These modular access routers can be configured with the ADSL WICs for primary WAN access and an ISDN WIC for WAN backup. This scenario provides redundancy for mission critical applications (Figure 2).

Figure 2. ADSL Access with ISDN Backup

Business Class Security

The Cisco 1700/1800/2600/2800/3700/3800 series routers can be optimized for Internet security with Cisco IOS Firewall supporting stateful inspection firewall and intrusion prevention system features. With an always-on DSL connection, Internet security is vital to protect corporate resources from malicious network attacks. These features can be enabled on the modular routers by purchasing the optional Cisco IOS image with the Advanced Security feature set.
In addition, the platform can be optimized for virtual private networks (VPNs). VPNs allow secure use of the Internet for communications with the same policies and levels of security and performance as a private network. VPNs provide security through encryption tunneling, and the Cisco routers support hardware-based 3DES IP security (IPSec) and Advanced Encryption Standard (AES)* support. Encryption features can be enabled on the routers by purchasing the optional Cisco Advanced Security IOS image.
* AES hardware support is currently only available on the 1800/2600/2800/3700 and 3800 Series Routers.

IP and ATM Quality of Service

Cisco 1700/1800/2600/2800/3700/3800 series routers with the ADSL WIC enable service providers to offer differentiated service options based on premium, standard, or best-effort service classes. The routers employ QoS features such as application-aware networking with IP QoS features and traffic management with ATM CoS features.

Application-Aware Networking with IP QoS

Using Cisco IOS Class-Based Weighted Fair Queuing (CBWFQ), the Cisco 1700/1800/2600/2800/3700/3800 series routers with ADSL WIC enable service providers and resellers to offer services, which can differentiate bandwidth based on a specific application or a specific user. For example, an order entry department's traffic can be given priority over a marketing department's traffic.

Traffic Management Using ATM CoS

In addition to IP QoS features, the Cisco 1700/1800/2600/2800/3700/3800 series routers with the ADSL WIC provides mapping of IP QoS to ATM class of service (CoS) features. These features enable service providers to manage their core ATM network infrastructures to deliver scalable, cost-effective services with QoS guarantees to their customers. Per-virtual-circuit traffic shaping and queuing allows further optimization of the existing bandwidth between customers and various services. (Table 1 below shows a summary of the QoS features.)

Performance

ADSL performance varies according to a variety of factors including DSLAM linecard type, DSLAM Software version, training rate, line noise, and loop length.

Software Support

The ADSL feature is supported in the IP/ADSL Image ("y7" image) for the Cisco 1700 Series. Cisco 2600/3600/3700 series routers require a PLUS IOS image for ADSL if using 12.2T. From 12.3 Mainline and beyond ADSL WIC support is available in the "IP Base" feature set. Some QoS features require an advanced image (IP PLUS, IP VOICE, or above) for Cisco 1700/2600/3600/3700 series router support. The ADSL WICs are supported on the "IP Base" feature set for the Cisco 1800/2800/3800 ISRs. The default IOS image for the Cisco 1841 ADSL bundles is the Cisco IOS IP Broadband image. In addition to all the features of the "IP Base" image, the IP Broadband image also has the Service Assurance Agent (SAA) features. The default IOS image for the Cisco 2800 series ADSL bundles is the Cisco IOS SP Services image.
The ADSL over POTS WIC (WIC-1ADSL), is available on the Cisco IOS 12.3 Mainline for the Cisco 1700/2600/ 3600/3700 series routers. This WIC is supported on the 1800/2800 series ISRs starting with the Cisco IOS 12.3(8)T Release, and on the 3800 series ISRs starting with the Cisco IOS 12.3(11)T Release..
The ADSL over POTS WIC with Dying Gasp Support (WIC-1ADSL-DG) is available on the Cisco IOS 12.3T Release starting with the Cisco IOS 12.3(7)T Release on the Cisco 1700/2600/3700 series routers. This WIC is supported on the 1800/2800 series ISRs starting with the Cisco IOS 12.3(8)T Release, and on the 3800 series ISRs starting with the Cisco IOS 12.3(11)T Release.
The ADSL over ISDN WIC (WIC-1ADSL-I-DG) is available on the Cisco IOS 12.3T Release starting with the Cisco IOS 12.3(7)T Release on the Cisco 1700/2600/3700 series routers. This WIC is supported on the 1800/2800 series ISRs starting with the Cisco IOS 12.3(8)T Release, and on the 3800 series ISRs starting with the Cisco IOS 12.3(11)T Release.
