Back to back (Point to Point) SHDSL connection

Below is a quick way to extend your network over SHDSL with speeds up to 4.6Mb over copper with Cisco's WIC-1SHDSL V3 modules.
(Symmetrical WAN speeds up to 2.3 Mbps over a single copper pair and up to 4.6 Mbps over two copper pairs using ITU-T G.991.2 Annexes A and B)
The config below is no means complete and requires hardening before adding this into production.
  • The basic RIP routing protocol was used to get the network running.
  • The Lab was setup with two Cisco 1841 Routers with WIC-1SHDSL V3 modules installed into slot 0 on each router
  • A 2 pair crossover cable with RJ11 connectors was used between the two routers (Cisco Lavender RJ11 ADSL Cable).
  • The two cards need to be set with roles, Head Office (CO) and Customer-provided equipment (CPE)
