Telephone Filters

A telephone filter must be installed on each of the telephony devices that share the same telephone number as your Optus DSL Broadband service. These include:
- telephones
- fax machines
- dial-up modems
- answering machines
- some digital pay TV equipment
- any other similar device.
Place a filter on all telephones or similar devices at your premises by unplugging the telephone cord and placing a filter between the phone and the wall socket as shown.
If you have a home monitoring service (Back to Base security or medical alarm) that uses the same phone line as your DSL service, it is your responsibility to arrange for a central filter to be installed in your premises. If you do not do this, you will experience problems with your DSL connection and your monitoring service. If you require further information about central filters please call Optus DSL Broadband Customer Service.
