NB8/NB8W ADSL2+ Modem Router 3
YML804 Rev1
Overview
Thank you for purchasing the NetComm NB8/NB8W ADSL2+ Modem Router. NetComm is proud
to introduce this entirely new class of all-in-one device incorporating ADSL2+ and Wireless in a
single compact unit. The NB8/NB8W is truly a ‘broadband communications gateway’ that, when
attached to the appropriate ISP services, will enable multiple broadband communications streams
to run concurrently into your home or office. Wireless and ethernet data services can be delivered
and distributed to multiple PCs at the same time, while the gateway can be managed via ‘Quality of
Service’ (QoS) controls to ensure that priority is given to the traffic of your choice.
Let’s look at some of the capabilities offered by the NB8/NB8W in brief:
ADSL Broadband The NB8/NB8W offers the next generation of
broadband ADSL technology with ADSL2/2+, which
boosts ADSL’s performance significantly, improves
interoperability, and supports new applications,
services and deployment conditions.
Wireless (NB8W only) In addition to fast, standard 802.11g-based wireless,
the NB8W incorporates Broadcom’s state-of-the-
art XPress and Afterburner technology to radically
improve the performance of wirelessly-connected
devices.
QoS With the addition of bandwidth-hungry applications
to the SOHO/Home network the NB8/NB8W has
not overlooked one of the most important features
for a home Internet gateway – Quality of Service
(QoS) The QoS implementation in the NB8/NB8W
is extremely sophisticated allowing you to prioritise
data on your network according to rules you make.

Minimum System Requirements:
Different aspects of the NB8/NB8W have different requirements, so let’s look at them in turn. We’ll
start with your computer, which ought to match the following requirements if you are to enjoy the
benefits of a high-speed ADSL connection and use of Wireless Networking (for the NB8W only).
PC Requirements:
• Any computer running Windows 98/2000/Me/XP or Macintosh OSX

ADSL Requirement:
• ADSL broadband connection to an ISP (Internet Service Provider)
• ADSL Splitter/Filter (see below for details)
Note: Connection at ADSL2 or 2+ rate depends on the service offered by your
ISP; the device will operate at standard ADSL rates in the absence of the
2 or 2+ service. Consult your ISP for details.

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. The following
diagram gives an example of connecting your ADSL Modem/ Router using a Microfilter. A suitable
Microfilter can be purchased from NetComm or your Service Provider, if required.
A central splitter may be installed with your ADSL service 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 on
each device.- Check with your ADSL or phone service provider if you are unsure as to whether a
splitter is installed at your premises.
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 extension will also
require Microfilters. The following diagram gives an example of connecting your ADSL Modem/
Router using a Microfilter.
A suitable Microfilter can be purchased from NetComm or your Service Provider, if required.
