The procedure for connecting an asymmetric digital subscriber line (ADSL) depends on the router and, in some cases, on the location. Follow the steps shown after Figure 4-15 to connect the ADSL cable to a cable wall jack. Note The DSL line must have been provisioned by your service provider and correctly configured for the ADSL CD LED to show the status. If the ADSL CD LED is not on, check with the DSL service provider. Note You must provide the unshielded Category 5 cable for connecting to the ADSL ISDN splitter that is provided by the service provider. Caution Cisco Systems DSL WAN Interfaces are tested for compliance with regulatory standards such as FCC Part 68, ITU-T K.21, IEC 61000-4-5, and CSA/EN/IEC/UL 60950-1. These standards assume Primary Protection devices protect the Customer Premise Equipment (CPE).
