Do I need a filter if I'm faxing over a DSL line?
- Yes. If you have a DSL or ISDN connection, you must connect the appropriate DSL filter or ISDN terminal adapter or router to the wall jack to be able to use the line for faxing or voice calls on your product. Contact your DSL or ISDN provider for the necessary equipment.
