Telephone base installation (2-line jack)
If you subscribe to high-speed Internet service (Digital Subscriber Line - DSL)
through your telephone lines, you must install a DSL filter between the
telephone base and the telephone wall jack. The filter will prevent noise
and caller ID problems caused by DSL interference. Please contact your DSL
service provider for more information about DSL filters.
The telephone line cord can be plugged into LINE 1/L1+L2 or LINE 2
telephone jack in the telephone base. However, it is suggested to plug the
telephone line cord with two telephone numbers into the LINE 1/L1+L2
telephone jack if you intend to connect the telephone to a fax machine or
modem through the DATA port.
If you have a 2-line wall jack, install the telephone base as shown below.
