Cisco multiservice access routers and integrated services routers offer a wide variety of WAN connectivity modules to accommodate the range of application needs in customer networks. The new Cisco 1-Port G.SHDSL WAN Interface Card (part number WIC-1SHDSL-V3) offers G.SHDSL-based WAN connectivity for modular routers deployed in small to medium-sized branch offices.
• 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 184.108.40.206.3 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
• 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.
