<div class="moz-cite-prefix">The regulations you are looking for is
the mandatory Industry Code C559 Unconditioned Local Loop Service
(ULLS) Network Deployment<br>
<br>
<a class="moz-txt-link-freetext" href="http://www.commsalliance.com.au/Documents/all/codes/c559">http://www.commsalliance.com.au/Documents/all/codes/c559</a><br>
at least read Part 1 and Part 2, and Deployment Class 6h in Part
3.<br>
<br>
Regulatory-wise, you could in theory run the DSLAM at full power
since it is on private copper lines (almost identical to
in-building copper up a building riser if the DSLAM is installed
in the basement) and C559 only has regulatory effect on
outside-plant copper, so you couldn't be hauled up in front of
ACMA.<br>
<br>
However don't do this - as John pointed out, this would cause
mid-point injection crosstalk issues and completely clobber any
DSL services that anybody has running from the exchange in the
same binder. The other services will also clobber your lines'
upstream signal. It could be viewed as anti-competitive conduct
interfering with services from other carriers and you might find
yourself explaining it to the ACCC instead, and all your pissed
off residents with exchange-based DSL that used to work.<br>
<br>
What you CAN do is apply an attenuating pad factor to reduce the
output power of your DSLAM to the same signal levels that an
exchange-based service would have by the time the signal reaches
from the exchange to your MDF. This is what Telstra DSLAMs in RIM
cabinets do to avoid clobbering exchange-based services. Then you
cause no more cross-talk than another exchange-based service on a
parallel line. You might be able to do this in your DSLAM
software. Speak to your DSLAM vendor.<br>
<br>
<br>
see <a class="moz-txt-link-freetext" href="http://www.commsalliance.com.au/Documents/all/codes/c559/ndcs">http://www.commsalliance.com.au/Documents/all/codes/c559/ndcs</a>
for the approved attenuation pad factors - the further your
private MDF is from the exchange, the more attenuation you need to
apply. <br>
<br>
If your private MDF is a long way from the exchange, you could
also apply a mask to your DSLAM output to prevent it transmitting
on the low frequencies that exchange-based services would still be
using, and just use the higher frequencies that have died out from
exchange services at the distance of your MDF from the exchange,
so the cross-talk will be invisible to exchange-based DSL services
- just use the high frequencies, and use them at full power. You
won't get 24 Mbps - but you might be able to provide higher
linerates than exchange-based services can.<br>

<p class="MsoNormal">Hi Paul,<br>
<br>
If you feed ADSL backwards into the network you will be in
breach of the band plan and create cross talk havoc.<br>
It would be possible to filter the lines, but this would
need technical approval, SO41 and SO43 would apply.<br>
<br>
Most decent DSLAMs have CO filters and seperate connections
for the CO side.<br>
However I doubt these are designed to meet the band plan,
but more likely provide impedance stabilisation at ADSL
frequencies.<br>
<br>
Cheers,<br>

<p class="MsoNormal">With the VDSL solution it will be a

wondering what regulations might be affected and whether we

to the residents, I suppose just like at the Exchange but in
their MDF instead.<o:p></o:p></p>
