Precisely - these were the Tasmanian units - supplied by a different vendor to the
mainland units.

According to
http://www.nbnco.com.au/assets/documents/nfas-product-technical-specification-2.0.pdf,
page 81:

"The battery backup unit will contain the following LED indicators showing battery status:

  * Mains Power OK
  * Battery Status (OK, needs replacing, failed).
  * Running on battery backup (lit when mains power fails).
  * A series of beeps are also provided to indicate the above conditions.

*NBN Co's remote monitoring service will enable Access Seekers delivering services
through a UNI-V to identify when a NTU is not being supplied with power."

*An RSP using the PSTN port should receive a network alarm from NBN Co's OSS when the
NTU loses power. Yet to see if the OSS can send through battery health information
*before* it loses power.
