Cisco WIC-1SHDSL-V3 enterprise networking (router/Catalyst switch/UCS families) Router Line Card

The Cisco WIC-1SHDSL-V3 is a single-port G.SHDSL WAN interface card with four-wire support, fitted to a Cisco router to provide a symmetric high-speed DSL WAN connection. G.SHDSL delivers matched upload and download speeds over standard copper pairs, and the four-wire (two-pair) mode this card supports allows higher bandwidth than a single-pair connection where the site’s cabling and the DSLAM at the exchange both support it. It is a routine WAN interface option for branch routers using leased or business-grade SHDSL circuits rather than asymmetric consumer ADSL, common in regions or use cases needing guaranteed symmetric bandwidth. It remains in service on established branch-router deployments still running SHDSL WAN circuits. Tech-Star supplies genuine Cisco WAN interface cards for maintaining established SHDSL connectivity.
