your BigPond Gateway has been allocated to on page 01 of this booklet. Your BigPond

Network Gateway connects to the NTD, connecting you to the fibre network.
nbn poWer supply unit (nbn psu)
The NTD is powered by the NBN Power Supply Unit (NBN PSU) which must always be
directly connected to mains power supply directly – not through an extension cord, double
adaptor, power board or any other kind of secondary plug or socket.
Your NBN PSU does include a battery backup feature. However, as the battery only
provides power to the UNI-V ports in the event of a power outage, this doesn’t provide
back-up for your Telstra Digital Voice or broadband services. If a battery backup is fitted,
we recommend that you maintain your batteries as described in the NBN Co User Guide.
If your mains power supply fails or you turn off the power or unplug the NBN PSU,
your Telstra services on the NBN will no longer work.
nbn psu alarms
The NBN PSU has serval types of audible warning alarm sounds. The following list includes:
Although the battery backup won’t support Telstra services on the NBN, we recommend
that you replace the battery when the Replace Battery warning alarm sounds and/or your
NBN Power Supply Unit is showing a red light next to the ‘REPLACE BATTERY’ symbol.
Details of the battery required and the instructions for replacing your backup battery are
available in your NBN Co User Guide.
