1. Connect the two long telephone line cords to the telephone. How you connect the telephone line cords to the wall is determined by your telephone service. Determine if you have one or two-line telephone wall jacks and if you receive DSL (digital subscriber line) service. If one or more of the telephone lines has DSL service, see Important information for DSL users, pages 6-8. Use only the line cords that come with the phones. If you need additional cords, visit our website at www.telephones.att.com or call 1 (800) 222-3111. In Canada, dial 1 (866) 288-4268.
•If you have two-line wall jacks, you can just plug the line cords into the wall jacks. Use Illustration A on page 11.
•If you have one-line wall jacks, you need to purchase one or two two- line adapters. Adapters are available at retail stores, by visiting our
website at www.telephones.att.com or by calling
