Integrated Services Routers Generation 2 (ISR G2) routers offer a wide variety
of WAN connectivity modules to accommodate a wide range of application needs in
customer network deployments. The Cisco Multimode VDSL2 and ADSL2/2+
Enhanced High-Speed WAN Interface Card (VDSL2 and ADSL2/2+ EHWIC) supports
DSL multimode, including very high speed DSL (VDSL2) and asymmetric DSL
(ADSL2/2+) over plain old telephone service (POTS) or an integrated services digital
network (ISDN). VDSL2 and ADSL2/A2+ are supported on a single WAN interface
and thus this card provides a secure, cost-effective solution for a wide range of
customers ranging from teleworkers and small businesses to large enterprise branch
offices.

Product Overview
The Cisco Multimode VDSL2 and ADSL2/2+ EHWIC (EHWIC-VA-DSL) provides 1-port multimode VDSL2 and
ADSL2/2+ WAN connectivity (Figure 1). In combination with the Cisco 1921 and 1941 Integrated Services Routers
(ISRs) and Cisco 2900, 3900, and 3900E Series ISRs, this EHWIC provides high-speed digital data transmission
between customer premises equipment (CPE) and the central office (DSL access multiplexer [DSLAM]), usually
located on the telephone company premises. This capability enables service providers and resellers to offer
additional services such as business-class security; voice, video, and data; differentiated classes of service
(QoSs); and managed network access with Cisco IOS
®
Software over existing telephony infrastructure. These
value-added features, along with the flexible manageability and reliability of Cisco IOS Software, provide the
mission-critical networking features that businesses expect.
With Cisco IOS 15.1(3)T/15.1(4)M and later releases, the 1-port multimode VDSL2 and ADSL2/2+ EHWIC is
supported on the following Cisco ISR G2 routers: Cisco 1861E, 1921,1941, 2901, 2911, 2921, 2951, 3925, 3945,
3925E, and 3945E ISRs. The Cisco 1861E ISR is supported starting with Cisco IOS Software Release 15.1(4)M.
