Getting started Telephone installation 2. Connect the telephone line cord(s) and the power cord to the telephone base. If you subscribe to high speed Internet service (DSL - digital subscriber line) through your telephone line, you must install a DSL filter between each telephone line cord and telephone wall jack. The filter prevents noise and caller ID problems caused by DSL interference. Please contact your DSL service provider for more information about DSL filters. Option 1: If you have a two-line wall jack, install your telephone base as shown below. Plug the other end of the black telephone line cord (4-conductor) into the wall jack.
