Green concerns raise ire for NBN battery backup
Potential environmental impact of recycling millions of batteries a
concern as NBN installs default backups for fibre homes
by James Hutchinson (Computerworld) 23rd February, 2011 12:49
The Department of Broadband, Communications and the Digital Economy is
preparing to consult with internet service providers on the potential
impact of recycling backup batteries for equipment installed as part of
the National Broadband Network (NBN).
The batteries are currently being installed by NBN Co contractors free of
charge on all premises connected by fibre-to-the-home (FTTH) technology.
The batteries are expected to provide power to the network termination
unit at homes and business for a minimum of three hours in the event of a
power failure, allowing users to make emergency calls.
The batteries themselves are likely to last up to five years and NBN Co
and service providers will both be able to monitor the lifespan of the
backup equipment, with an alarm set to warn both operators when the
battery requires replacement.
According to NBN Co chief executive, Mike Quigley, the service provider
will be responsible for maintenance and replacement of the battery after
it is installed.
However, in a Senate estimates hearing this week, Greens senator Scott
Ludlam questioned the potential environmental impact the millions of
batteries could have when they do require replacement and ultimately
Marianne Cullen, first assistant secretary of NBN implementation at the
department, told senators the department would relieve any responsibility
from NBN Co, and was looking to address the environmental and emergency
service issues with industry.
Were currently in the process of designing an appropriate stakeholder
consultation process in the department and expect that to happen in the
next couple of months, she said.
An investigation into the battery issue last year by Communications
Alliances NBN working group led to suggestions the backup be provided as
an optional install for those users who require a voice service.
Layer 10 consultant and former lead of the working group, Paul Brooks,
told Computerworld Australia the use of an optional battery installation
could potentially alleviate the environmental impact by reducing the
number of batteries installed in the first place.
Anybody who actually needed the battery backup could have it, but the
people who didnt need the battery backup because theyre using phone
handsets or mobiles or other means of communicating shouldnt be required
to have the battery to reduce the huge environmental impact of having
tens of millions of batteries replaced every few years, he said.
The batteries are primarily designed to back up the voice service on NBN
equipment, but one of the remaining unclear questions is whether the
battery would also provide power to data ports.
The lack of a backup option for data could provide hazardous as RSPs may
offer VoIP services over the existing data connection, rather than using
the emulated telephone port on customer equipment.
Spokespeople for NBN Co and equipment supplier Alcatel-Lucent did not
respond to requests for comment at time of writing.
According to technical specifications released by the network wholesaler
last year, satellite-connected homes will not receive the battery backup
device by default, as the approximately three per cent of Australian
premises will only be offered a voice service through existing universal
service obligation arrangements, or through a VoIP service provided over
the data connection.
NBN Co is yet to confirm whether fixed wireless premises will receive the
However, both Quigley and Brooks warned that, even with battery backup
for the voice ports on customer equipment, the prevalent use of cordless
phones and handsets requiring power meant that the battery would be
useless in emergency situations.
When people are using a cordless phone, it doesnt work when the power
goes out, Quigley said.
Quigley also revealed at Senates estimates that NBN Co continued to
investigate a reserve button for the battery backup unit.
In a statement to ZDNet last month, a spokesperson for the wholesaler
indicated the button, which could only be pressed by an authorised
technician, could be used to deliver a further 25 per cent of the
batterys power reserve after five hours of use without main line power.
Communications minister, Senator Stephen Conroy, called the reserve power
button a break glass in case of emergency option.
