Do I need a micro filter?
Micro filters are used to prevent interference between phones and fax machines, and your ADSL service. If
your ADSL-enabled phone line is being used with any equipment other than your ADSL Modem then you will
need to use one Micro filter for each phone device in use. Telephones and/or facsimiles in other rooms that
are using the same line will also require Microfilters. A suitable Microfilter can be purchased from NetComm
or your Service Provider, if required.
Multi-purpose Gateways and In-line Splitters
The multi-purpose ADSL/VoIP gateway uses a different micro filter configuration to an ADSL modem/router.
With the NB9/NB9W, an in-line splitter is placed between a telephone outlet and the NB9/NB9W. One RJ11
cable is then connected from the splitter’s
Phone port to the NB9/NB9W LIne port. Another is connected
from the splitters ADSL or MoDeM port to the NB9/NB9W ADSL port. This is to allow the ‘pass-through’ line
to connect via the POTS if necessary. (See diagram on page 9)
