Cisco 828 and SOHO 78 G.SHDSL routers offer an affordable broadband WAN access solution that can be carried over existing copper telephone lines. The routers provide a symmetrical WAN connection at speeds up to 2.3 Mbps with
a 20,000-foot distance limitation. As with asymmetric DSL (ADSL), G.SHDSL solutions typically are deployed by service providers connecting G.SHDSL routers with DSL Access Multiplexors (DSLAMs) or IP multiservice switches that contain corresponding G.SHDSL
line cards. However, the technical specifications for the G.SHDSL standard allow two G.SHDSL routers to directly connect with copper wiring
in a back-to-back configuration. This back-to-back scenario allows two Cisco 828 or Cisco SOHO 78 G.SHDSL routers to connect without a DSLAM or IP DSL Switch between the units.
