1-Port ADSL WAN Interface Card. This
feature module describes the 1-port Asymmetric Digital Subscriber Line
(ADSL) Wide Area Network (WAN) Interface Card (WIC) feature. It
describes the benefits of the feature, supported platforms,
configuration, related documents, and provides command reference
information. The ADSL WICs are available in
two variations: ADSL over POTS (WIC-1ADSL), and ADSL over ISDN WAN with
Dying Gasp support (WIC-1ADSL-I-DG). 
The following bullets summarize
the features of each card:
•
Cisco WIC-1ADSL—Provides
ADSL services over ordinary telephone lines. It is compatible with the
Alcatel Digital Subscriber Loop Access Multiplexer (DSLAM), the
Cisco 6260 DSLAM with Flexi-line cards, and the Cisco 6130 DSLAM with
Flexi-line cards.

•Cisco WIC-1ADSL-I-DG—Provides ADSL
services in areas of the world that have extensive ISDN backbones
already in place. It is compatible with ECI, Siemens, Alcatel, and Cisco
DSLAMs that support ISDN.

All
Cisco ADSL WICs support Asynchronous Transfer Mode (ATM) Adaptation
Layer 2 (AAL2) for the Cisco 2600, Cisco 3600, and Cisco 3700 series
only, and AAL5 for the those models as well as for the Cisco 1700. The
cards support various classes of Quality of Service (QoS) for both voice
and data.
Benefits
Both Cisco ADSL WAN interface cards provide the following benefits:
•Enable business-class broadband service with voice integration, scalable performance, flexibility, and security

•Support
ATM AAL5 services and applications, ATM class of service (constant bit
rate [CBR], variable bit rate-nonreal time [VBR-NRT], variable bit
rate-real time [VBR-rt], and unspecified bit rate [UBR]), as well as up
to 23 virtual circuits on a WIC in Cisco routers
