ROUTES
A single route using PPP (including PPPoE and PPPoA) and a second route using static or
dynamic IP are concurrently supported. The following combinations of ports and protocols are
possible.
Port Protocol Port Protocol
ADSL Modem PPPoE/PPPoA and ETH/DMZ IP
ISDN PPP and ETH/DMZ IP
For example, the ADSL Modem could be used to connect to the Internet for web browsing and
the ETH/DMZ port could be connected to a gateway into a private wide area network.
FIREWALL
The module is equipped with a firewall that has the following features:
• Stateful Inspection
• Packet Filter Definition
• Network Address Translation
• Intrusion Detection
• Security Logging
VOIP
The BROADBAND MODULE is equipped with a VoIP gateway with the following features:
• 2 endpoints which support IP trunks
• Proxy server registration
• Codecs - G.711, G.729
• Quality of Service
The BROADBAND MODULE PLUS is equipped with a VoIP gateway with the following features:
• 12 endpoints which support trunks, extensions, unified messaging or any combination
of all three
• Proxy server registration
• Codecs - G.711, G.729
• Quality of Service
BANDWIDTH REQUIREMENTS
The BROADBAND MODULE and BROADBAND MODULE PLUS support two different codecs,
each with different bandwidth requirements. In addition to the bandwidth used by a codec, there
is also an overhead imposed by the various protocols used in transporting the IP packets as well
as signalling. When this is taken into account, the actual bandwidth required for each codec
increases significantly.
In order to ensure good voice quality, it is recommended that the following bandwidth is
available on the broadband connection for IP trunks and extensions

Codec IP Trunk or Extension
G.711 100 kb/s
G.729 50 kb/s
NUMBER OF VOIP CHANNELS
The following chart shows the bandwidth required to support up to 12 VoIP channels. When
calculating the number of VoIP channels that can be used over ADSL, always use the lower
(upload) data rate. Note that data applications for browsing etc., will require additional
bandwidth.

SETTING UP IP TRUNKS
The following procedure is used to set up the BROADBAND MODULE and the BROADBAND
MODULE PLUS to operate with the BT Broadband Voice service.
A broadband connection must first be established before VoIP can be programmed. Refer to the
VoIP section (page 6) to find out how many IP trunks can be supported on your broadband
connection.
When you subscribe to the BT Broadband Voice service, you will be given a URL to link to and a
username and password. Connect to the URL from any PC on the LAN and enter the username
and password. The VoIP trunks will then be automatically configured.
To verify that the trunks have registered with the BT Broadband Voice service
• Select “Status” from the main menu, scroll down to VoIP and verify that each trunk has
registered as indicated by .
SETTING UP IP EXTENSIONS
The BROADBAND MODULE PLUS supports up to twelve IP endpoints which can be configured
as either trunks, extensions, or a combination of both. Note that when Unified Messaging
Service is required, one endpoint must be permanently assigned to it.
V-IP Featurephones must be used as local or remote extensions. (Note that other manufacturers
IP phones will not work with the system). Refer to the V-IP Featurephone Quick Reference User
Guide for setting up and connecting the phone.
