Dacs ??????
A friend of mine is wanting Broadband and did a line check, this is what came up. I have nver heard of line sharing with a neighbor before????
They live in a new (built last year) block of flats, 3 high. and live across the road from the exchange. Your telephone exchange ***** does support ADSL however as BT have installed a DACS on your line you will be unable to get ADSL until it is removed, as a DACS makes your line incompatible. A DACS is a line sharing device and is installed for BT have not laid enough physical cables between your street and the telephone exchange. What happens is you will physically be sharing the sames wires with probably your neighbour. Full details about DACS and how to get them removed can be found in the relevent section of our ADSL Sales pages, the part regarding DACS conversions. In summary you place your order as normal with us and if BT decide it is finanically viable (costs less than £1000 from their own pocket!) they will do the DACS conversion, this tyically involves either moving someone else in your place onto the DACS or if that is impossible laying fresh cables from your exchange to your street. |

i heard of this when i was looking for my cousin.
but from what i've read in the above post i can't work out why he has this as he live next door to my gran who does not have DACS and there are no other neighbours where he live so it's very strange. |

DACS is a system that BT uses to split a standard telephone line into two separate lines. This is usually done when there are capacity problems at an exchange. This may have been put on your line a long time ago, you would notice that dial-up internet wouldn't reach over 28k (except odd occasions it might make 33k).
Just let your chosen ISP put the order through, they will contact BT who will send an engineer out to remove the DACS from your line if there is now enough lines to do so, swap it over to other lines, or isn't to expensive to add more lines. |

It isn't really anything to do with capacity at the exchange at all, rather the capacity where the property actually is and how many wires run there.

I got a DACS and ordered broadband. It means BT have to do two or three tests on the line and send an engineer out to remove the DACS. This can mean up to 7 or 8 days delay in gettting your broadband switched on. Im getting broadband this week. An engineer is due to come to me thursday to take the DACS out. After I got my welcome pack last week. In some cases years ago it was easier for a BT engineer to fit a DACS in the house then split the line at the BT telephone poll.

daccs.
DACS is used to do crossconnects and is mainly used to organise capacity. DACS is not a physical thing, but computer software. What it means is that the connection that your house attaches to in the street instead of directly relating to data on the switch (telco exchange) is linked up through DACS so that it doesnt have to link up with specific data but means it can be connecting to different connections in the street. A technician will just change you to a non daccs "pair" in the street.

to put it simply. Its a way of "virtually" connecting you to any free pair on the BT network.

I got my Dacs tane out the day and my Tiscali dial up now seems a little faster. Im to change to 512MB BTYahoo broadband option 2 over the weekend. Then im to get 1GB broadband next thursday when they close one of the phonelines going into the house and I use just the one line.

Sure you don't mean you'll have 512Kbps and then will be upgraded to 1Mbps?

Anyone else having problems with BT removing DACS? I have read that if it costs more than £1,000 they refuse to do it. I know 2 people who have been refused recently and have seen that there are problems with DACS all over the country. There also seems to be discrimination between business customers and ordinary customers.

BT Wholesale would get screwed if that was true. |

See this page on Ofcom's website about DACS. I have posted it on another forum and have been informed that someone has used this to get BT to remove the DACS, enabling the person to get broadband.

If the business order was placed first it would get the service first. Why don't you forward your allegations on to OFCOM? |

Dunno what your on about mate but what he said about dacs was right. Slow dial up speeds and it is a physical box at the telegraph pole and a piece of equipment in the telephone exchange. There is nothing virtual about it. If people have got dacs on there line and they order broadband then openreach will come out and remove it. Simple. |

The other DAC's is a digital cross-connect switch used to organise SDH circuits, eg a 4:3:1 DACCs will take an STM-4 (622Mbps) & break it down to E1's. Similar acronym, but different boxes. |
