Cisco G.SHDSL High Speed WAN interface Card - DSL modem - HWIC - 5.696 Mbps - analogue ports: 4 - for Cisco 1841 3G, 1841 ADSL2, 18XX, 1921 4-pair, 1921 ADSL2+, 19XX, 28XX, 29XX, 3825, 39XX

The Cisco 4-pair G.SHDSL High Speed WAN Interface Card is designed to deliver high-speed Ethernet services over SHDSL access. HIWC-4SHDSL-E allows bonding to achieve higher data rates as defined by IEEE 802.3ah, and it is typically used in scenarios where individual links are aggregated using the 802.3ah loop aggregation. This card is supported in all Cisco ISR (except the Cisco 3825 and 2811) and ISR G2 routers that have HWIC slots.
The HWIC-4SHDSL-E cost-effectively allows service providers and enterprise customers to deliver Ethernet services to sites with no access to fiber by using bonded copper pairs with symmetrical bandwidth at rates up to 4 x 5.696 Mbps.
The HWIC-4SHDSL-E together with Cisco ISRs provides businesses the necessary bandwidth for critical traffic such as voice and video conferencing, and enables customers to save money by integrating voice and data traffic on the same WAN link. Service providers can increase subscriber revenue by bundling services and offering differentiated service levels through service-level agreements (SLAs).
This Interface Card enables point-to-point Ethernet connectivity, which uses existing infrastructure of copper wires spanning a typical carrier service area (CSA) of 9,000 to 12,000 feet from a central office to the customer premises.
