Cisco - DSL modem

The G.SHDSL WAN interface card (WIC) provides 1-port symmetric high-bit-rate DSL (SHDSL) connectivity to a WAN. This interface card is the latest G.SHDSL-based WIC for Cisco modular routers. It supersedes existing interfaces.

G.SHDSL technology offers customers high-speed, symmetrical WAN connectivity at a lower monthly cost than most traditional WAN circuits. Using single or dual-pair copper wires, Cisco access routers with SHDSL interface card can provide businesses the necessary bandwidth for critical traffic such as voice and videoconferencing, and can allow 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).

A product of the ITU-T, SHDSL is the first standardized multirate symmetric DSL technology. It is designed to transport rate-adaptive symmetrical data across a single copper pair.
