BT always try and remove the DACS when a ADSL order is received - they have
an internal budget of around £900 if any work is needed.

BT almost always manage to remove the DACS automatically as part of the ADSL
order process (the order may take a few days longer to process , thats all)
but its not guaranteed if BT find they can't do it for any reason.

It could have been that there was not a "spare pair" at the time but there
is now or it was just easier for the engineer to install a DAC's unit.

BT could always move the DAC's to a neighbours line so you can get ADSL..

bear in mind that no matter what the line or distance from the exchange
there is never any guarantee that they will be able to supply broadband

The property we are purchasing has a dacs fitted (well the bt bband checker
suggests this) & after a call to BT to discuss the possibility of getting
broadband at the property they report that if an order is placed for
broadband they will remove the device and give the property a dedicated
line.

Not that I doubt BT or anything but could there be a condition by which they
could turn around and say sorry, not possible due to some reason or other
(i.e not enough lines available etc - or will they always (as they seem to
imply) be able to get rid of the dacs. Makes me wonder as to why a dacs was
fitted in the first place (except for lazy engineer) if they could guarntee
to get rid..

TIA

I am old enough to remember the days when PO Telephones offered you a party
line because they didn't have enough infrostructure. DACS to me is a similar
situation. The trouble is that BT don't even have the good manners to tell
you that they are going to DACS your line, and if you are using dial-up
internet it will seriously affect your speed.

99% of the time it will be possible for the DACS to be removed. As to them
being fitted due to lazy engineers, it's more like poor planning so there
was (& possibly still is) insuffcient line plant capacity...

Indeed (and see 13 below) but voice and fax users wouldn't even
notice.

As of December 2003 (implementation choice for an EU directive).

DACS is not an acceptable method of provision of service, according to
OFTel, if the customer wants Internet and the line could give a
performance significantly above 28.8 Kbs.

http://www.oftel.gov.uk/publications...03/uso0703.pdf

Annex B
"4. Oftel will consider that the Provider is providing functional
Internet access where it is able to demonstrate that it is making every
reasonable effort to ensure that lines achieve optimum performance,
particularly where the enduser intends to use the line for Internet
access.

"11. Oftel considers that where a line is fitted with a pair-gain
device, such as DACS, the line is unlikely to achieve optimum
performance.

"13. If, having exhausted other options, the Provider needs to fit
existing lines with pair-gain systems or transfer a pair-gain system to
another line, it should ensure that this will not adversely affect an
existing user of narrowband access to the Internet.

"28. The Provider should establish appropriate management and business
processes to: • monitor the level of complaints from end-users on
connection speeds for Internet access and assess the underlying causes;
• monitor the use of pair-gain systems within the network; • ensure
that the impact of pair-gain systems upon Internet access decreases
over time;"
