3. Initial Startup and Configuration7990-A2-GB20-20 September 2004 3-3Connecting to the NetworkProcedureTo connect the unit to the network:1. Plug one end of the network cable into the rear panel DSL jack.2. Connect the other end to the DSL network interface.NOTE:Do not use a flat VF network cable as this may severely degrade theperformance of the unit. Only use a Cat 5 twisted-pair network cable.Connecting to a DTEThe DTE interface varies from model to model.See Appendix C, Connectors, Cables, and Pin Assignments, for more information.Table 3-1.
