Telephone base installation (1-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 either LINE 1/L1+L2 or LINE 2
telephone jack. However, you have to plug the telephone line cord into
LINE 2 jack if you need to connect to a fax machine or modem through DATA
port. All data will only be transmitted through LINE 2 jack.
If you have 1-line wall jack, install the telephone base as shown below.
