Do I need a Micro filter?
Micro filters are used to prevent common telephone equipment, such as phones,
answering machines and fax machines, from interfering with your ADSL service. If
your ADSL enabled phone line is being used with any other equipment other than
your ADSL Modem then you will need to use one Micro filter for each phone device.
Splitters may be installed when your ADSL line is installed or when your current
phone line is upgraded to ADSL. If your telephone line is already split you will not
need to use a Microfilter - check with your ADSL service provider if you are unsure.
Each micro filter is connected in-line with your telephone or fax machine so that all
signals pass through it. Telephones and/or facsimiles in other rooms that are using
the same ex tension will also require Microfilters. The following diagram gives an
example of connecting your ADSL Modem/Router using a Microfilter.
