integrated services routers offer a wide variety of WAN connectivity modules to accommodate the range of application
needs in customer networks. The new Cisco ADSL2 and ADSL2+ high-speed WAN interface cards (HWICs) deliver business-
class asymmetric DSL (ADSL) services for customers ranging from small-to-medium sized businesses to enterprise branch
offices. Both, 1-port and 2-port HWIC cards are now shipping. While the 1-port HWIC card has an ADSL port, the 2-port HWIC
card has an ISDN BRI backup port in addition to ADSL port.
OVERVIEW
The new ADSL HWICs provide 1-port ADSL (Figure 1) connectivity to a WAN. These HWICs, combined with the Cisco 1841 integrated services
router (ISR) and the Cisco 2800 and 3800 series integrated services routers (ISRs), provide high-speed digital data transmission between customer
premises equipment (CPE) and a central office. This enables service providers and resellers to offer additional services by supporting features for
business-class security, voice integration, differentiated classes of service (CoS), and managed network access with Cisco IOS
®
Software. These
value-added features, along with the manageability and reliability of Cisco IOS Software technology, provide the mission-critical networking that
businesses require.
Both the 1-port and 2-port HWIC cards are supported on the Cisco 1841, 2801, 2811, 2821, 2851, 3825, and 3845 ISRs. The 1-port HWICs
are supported starting with Cisco IOS Software Release 12.4(4)T and the 2-port HWICs are supported starting with Cisco IOS Software
Release 12.4(6)T.
