The 2-pair symmetric high-bit-rate DSL high-speed WAN interface card (HWIC) provides G.SHDSL connectivity to a Wide Area Network. The 2-pair G.SHDSL HWIC provides two ports of 2-wire or one port of 4-wire connectivity options. This card is supported in all integrated services routers that have HWIC slots. The 2-pair G.SHDSL HWIC supersedes the existing G.SHDSL WAN Interface Card, which is a WIC-based G.SHDSL solution. The new G.SHDSL HWIC provides higher performance & increased reach when compared to the G.SHDSL WIC.G.SHDSL technology offers customers high-speed, symmetrical WAN connectivity at a lower monthly cost than traditional WAN circuits. The 2-pair G.SHDSL HWIC together with Cisco integrated services routers provides businesses the necessary bandwidth for critical traffic such as voice & video conferencing, & enable customers to save money by integrating voice & data traffic on the same WAN link. Service providers can increase subscriber revenue by bundling services & offering differentiated service levels through service-level agreements.
