The 4-pair symmetric high-bit-rate DSL high-speed WAN interface card (HWIC) provides G.SHDSL connectivity to a Wide Area Network. The 4-pair symmetric G.SHDSL HWIC provides two ports of 4-wire or four ports of 2-wire connectivity options. The 4-pair symmetric G.SHDSL HWIC also allows bonding single or dual-pair G.SHDSL ports up to a single 8-wire interface with increased bandwidth by using Inverse Multiplexing over ATM (IMA) or data interleaving with M-pair mode. This card is supported in all integrated services routers that have HWIC slots.

The 4-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 and 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 4-pair G.SHDSL HWIC together with Cisco integrated services routers 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.
