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.
