Many businesses today require data and voice connectivity between multiple buildings in a campus environment.
Often copper wire is the only means to interconnect each facility to a campus' main building. G.shdsl technology
allows customers to link two Cisco 1700, 2600/3700s with WIC-1SHDSL or WIC-1SHDSL-V2 cards back-to-back
over standard 26 AWG telephone wire and provide up to 2.3-Mbps WAN per copper pair connectivity between
the two sites (upto 4.6Mbps is possible using theWIC-1SHDSL-V2and two copper pairs). This enablesdeployment
of data, voice, and video over existing copper wire without a costly infrastructure upgrade. Multiple WIC-1SHDSL
or WIC-1SHDSL-V2 cards can be used to allow for additional bandwidth between locations.

Intranet toll-quality voice
The Cisco1700, 2600 and3700 combined with theWIC-1SHDSL or WIC-1SHDSL-V2enable interoffice voicecalls
to be sent across a DSL network, thus avoiding the charges incurred from a long-distance carrier, local exchange
carrier(LEC), orPort, Telephone,and Telegraph(PTT). Customerssimply leasean ATMvirtual circuit(VC) between
one or multiple sites and use VoATM or VoIP technology to pass Intranet voice traffic between sites.
