Benefit of Exchange Only?

Are there any benefits to an exchange only line?
I've a case where a 1200m exchange only line is one of two (next door neighbours) in amongst a mess of fttc cabinets, just racking my brain as to what could be offered over e/o that might not be available/as cheap as via a cabinet?
Etherways?
Any thoughts are greatly appreciated.
Cheers, flipdee

I can't think of any benefits of a long exchange only line over the same length line going via a cab - I guess I slight reduction in complexity/failure points as there is no cab in the picture but other than that nothing.

Were those two houses possibly show houses or builder's offices when the estate was built? Or perhaps an industrial building or mansion that ownd the estate land?

It was cheaper for BT to provide the telephone service back when the EO line was installed, rather than maybe build a cabinet for just one or two lines.

Hi Andrew, RobertoS, Ian72,
Thanks for your thoughts.
RobertoS, yes, I believe these were two separate houses built/connected at a much earlier/distinct time than the rest of the town.
Is there any currently available BT connectivity product which benefits from a line being E/O?
Clutching at straws a little I know.

Not that I know of, sorry.

Even non-domestic products?

Then the EO question is probably irrelevant. How many thousand squidoodles have you budgetted?

Your probably right, was just trying to think laterally about the current E/O fttc limitation.
If 100/150Mbps+ was still within a grasp of reality price wise, then it might be an option, but £1500 per month is a bit rough.

If these two houses are in amongst other houses which have FTTC then you might be able to pay for a network rearrangement, but it will cost £££££££

Oh well anyone can have a leased line installed if their pockets are deep enough

I was hoping for some magic in-between product i'm not aware of

Contact Harry Potter.

Is that £100000? or £XXXXXX (Number bigger than that) ?
Out of curiousity has anyone got involved in a network rearrangement?

The development where I live in central London (c75 1.8Km EO lines) was quoted £25K+VAT for the necessary network rearrangement to allow access to FTTC.

Hey MCM,
Thanks a lot for the info.
Do you know if they got a dedicated fttc cabinet for the 75 lines or was it just tacked on to the nearest existing cabinet?
Also was fttp priced as well?

We never proceeded much beyond the initial enquiry as there was no guarantee that BT's £25K+VAT would cover all of the necessary work. FTTP was never an option with BT.

Hyperoptic also surveyed and quoted us a figure of just under £20K but there were a number of problems with their proposal. The greater part of their estimate being the cost of deploying Ethernet around the development and some of the residents considered the necessary trunking to be unsightly and also had concerns about the two catenaries required where the Ethernet needed to cross a roadway and footpath.

Very interesting, thanks a lot for the info.
20k+ quite a lot of dough.

it woudl be a new new pcp and DSLAM and assuming the cab coube be close to the community then your be looking at aound 50 m/bps above for the end uders at a network - level -- we have done a couple incuding a communtuy g around 5km from the exchange -- the gap is determined by how much work and how many premsies covered

How many users were involved? Just curious as to the numbers the gap investment gets spread over.

Some but they may not make much of a difference;

The E-Side cables for those who chose to adopt FTTC will stop causing noticible crosstalk as they are connected, so they won't have any broadband service running through them - Less crosstalk - However the D-Side cables will still be in use. There is a slight chance you could get a slightly faster sync in a few months if FTTC has been rolled out recently, if people in your area adopt FTTC but don't hold your breath.

As for E/O lines; watch this space. Back in the village where I live (Nether Stowey), BT are rolling out FTTC (Exchange has 1,415 lines) and are also constructing a brand new PCP cabinet literally opposite the exchange which I can only guess is so they can pop an FTTC cabinet next to it allowing them to offer FTTC services to E/O lines.

Take a look at http://roadworks.org widen the search to 12 months and check near your exchange for new PCP cabinets. You could be lucky .

As for other options not really unless you are willing to fork out all that money for Openreaches' FTTP on Demand which I'm not even sure is available to those on E/O lines.

That's good point, I had forgotten there effectively isn't a D-side on E/O.
Sadly we don't get updates via roadworks.org here in Northern Ireland, so it's a case of keeping an eye out for some actual activity, much harder to do of course.

Cheers for all your info.

Actually, I think there can be, at least for EO cables that go off to remote locations.

Obviously not in the sense that there's a cabinet placed between the E-side and D-side cables. However, my understanding is that the construction style of the cables involved does *feel* like E-side and D-side; the difference is only that they are jointed underground rather than in a cabinet.

4800-pair cables, armoured, pressurised: definitely features of E-side cabling, not D-side.

Take a look near the end of this old thread (with some interesting info)

You definitely won't see an armoured main side cable.

There are two reasons for an e0 feed.

Firstly a small exchange with a few hundred circuits. Really this is not no dside, it's no mainside.

Secondly a large exchange where large main side cables have been used. Probably from the late eighties and early nineties where cabinets were out of fashion and pressurising as far as possibe and locking intercepts out was the idea .

The demarcation will be the airblock. You will not get local repair or installer guys interfering with main side cables. This is specialist, long duration stuff. They will be able to intercept after the airblock close to the punters as traditional dside work with small unscreened, grease filled cables.

There is no technical reason why a cabinet can't be cut into either. Just as there is no technical reason Virgin can't provide me service. It's just about the cost of doing the work versus the return.
