FEATURE SUMMARY
• Offers symmetrical WAN speeds up to 2.3 Mbps over a single copper pair and up to 4.6 Mbps over two copper pairs
• Based on ITU Recommendation G.991.2 (accepted worldwide)
• Supports Dying Gasp; uses power status bit (section 7.1.2.5.3 of G.991.2) for signaling
• Supports Wetting Current (Section A.5.3.3 of G.991.2)
• Supports G.SHDSL Annex A (U.S. signaling) and Annex B (European signaling)
• Multiple G.SHDSL WICs configurable per Cisco 1800, 2800, and 3800 and Cisco 1700, 2600XM, and 3700 router chassis
• Offers toll-quality voice over data with ATM Adaptation Layer 2 (AAL2) on Cisco 2800, 3800, 2600, and 3700 series routers; and AAL5 and
voice over IP (VoIP) on the Cisco 1800, 2800, 3800, 1700, 2600, and 3700 series routers
• Supports extensive ATM classes of service (CoS) and IP quality of service (QoS)
• Operates back to back or with DSL access multiplexer (DSLAM)
• Sustains up to 23 virtual circuits per WIC
SYSTEM REQUIREMENTS
• The WIC is supported on all modular Cisco integrated services routers—the Cisco 1841, 2801, 2811, 2821, 2851, 3825, and 3845. It is also
supported on the older multiservice routers—the Cisco 1721, 1751, 1760, 2600XM, 2691, 3725, and 3745 routers.
• The new WIC is supported on these access routers using the Cisco IOS IP Base feature set and up. For the Cisco 1700 Series, the minimum Cisco
IOS Software feature set required to support the card is IP/ADSL or IP Base.
• The routers listed previously need to run Cisco IOS Software Release 12.4(3) Mainline and above or 12.4(2)XA to support the new WIC. The
interface is also supported in Cisco IOS Software Release 12.4(3rd)T and above.
• The system requires no additional flash or DRAM memory other than the specified minimum memory for the Cisco IOS Software releases listed.
• No slot placement restrictions are placed for the new interface card on any of the platforms.

Feature Benefits
Flexibility
Cisco IOS Software Support
• Provides the industry’s most robust, scalable, and feature-rich internetworking software support using
the accepted standard networking software for the Internet and private WANs
• Constitutes part of the Cisco Systems
®
end-to-end network solution, including multiprotocol routing
(IP, Internetwork Packet Exchange [IPX, AppleTalk, and IBM/Systems Network Architecture [SNA])
and bridging
Integrated Voice and Data Networking
Voice and Data Integration
• Reduces long-distance toll charges by allowing the data network to carry interoffice voice and fax
traffic

for a costly phone-equipment upgrade
• Supports critical IP QoS features in Cisco IOS Software
• Provides traffic management with ATM CoS
Digital Voice Interfaces
• Provides toll-quality, award-winning derived VoIP; software-support VoIP/AAL5 and voice over ATM
(VoATM)/AAL2 (Cisco 2800, 3800, 2600, and 3700 only); and AAL5
