Overview
Thank you for purchasing the NetComm NB5 ADSL/ADSL2 Modem Router. NetComm brings
you the Next Generation of ADSL technology with ADSL-2*, which boosts ADSL's performance,
improves interoperability, and supports new applications, services and deployment conditions.
NetComm’s implementation of ADSL-2* and ADSL-2+* ensures that the NB5 operates with
existing ADSL services while delivering optimal performance in all modes of operation. Powered by
the latest ADSL-2* TI chipset, NetComm’s NB5 increases downstream data rates by up to 50%
(12Mbps) and 100% (25Mbps) for ADSL2 Plus* mode ensuring that you can surf the net or
download your files quicker than ever before.
With support for RE-ADSL-2* (Reach Extended), NB5 caters for those users who are outside of the
current range of an ADSL exchange by providing greater reach of ISP services. NB5 is truly there
for your ADSL future.
Security is a key issue with Broadband users and NetComm’s NB5 does not leave you exposed.
Employing the latest Active Firewall technology, NB5 checks every packet of data that comes in
ensuring your defenses are rock-solid against hackers, unauthorised entries, probes and even Denial
of Service attacks. What’s more, NB5 is equipped with a VPN pass-through feature allowing you to
use a standard VPN client for Point-to-Point communication even while your Firewall is active.
NB5 delivers the connection versatility needed to cater for today’s ADSL users. You can simply
attach the NB5 to a single PC by using the USB port. Alternatively, should you wish to share your
internet connection with up to 253 users, the NB5 is equipped with an in-built Router and a 10/100
Ethernet port for connection to a network system.
The NB5’s Port Forwarding and UPnP functions have made it easier for today’s Internet users to
configure and setup the myriad of Network Port Rules needed by internet applications such as On-
Line Gaming, Peer-To-Peer file sharing and Messenger services to operate. NB5 has a number of pre-
configured rules for several games, just click on the game you wish to play on-line and the rest is
done for you.
Added to this, NB5 introduces a QoS (Quality of Service) feature that gives you control over which
types of outgoing data are given priority by the router. With QoS you can tailor your router settings
to ensure that you can keep gaming or browsing even though your upstream bandwidth may be
saturated by applications such as Peer-To-Peer file sharing.
* Your ISP must support and provide you with an ADSL-2, ADSL-2+ or RE-ADSL-2 service for these features to be
available. This product will operate as a standard ADSL Modem Router when an ADSL-2 service is not available. The
NB5 may require a firmware upgrade to support ADSL-2, ADSL-2+ or RE-ADSL-2.
