Any CPs in here also suffering from Openreach imposing hefty excess
construction charges on new ISDN30e installs?

Is this for a site which needs new fibre?

JW brought next idea :

Spot on. It seems EVERY site, though admittedly not a terribly
representative sample, require fibre.

The copper delivery system (CWSS) has a distance limit of 3
to 4 km and can use existing network. Further than that,
fibre cable will be needed. I suppose old BT used to
swallow the network costs but Openreach may need to be much
more transparent. In future, we may need to think about
using multiple ISDN2e for some sites.

An order for data services might trigger the fibre
installation. BT sometimes does free installs on
Megastream, for instance.

JW explained on 10/12/2007 :

Interesting. At least one site that Im having a problem with is less
than that distance.


I think youre right.


And again.


That is certainly how Ive had to go. There is a plus side - the per
channel rental cost of ISDN2e is a fair bit less than ISDN30e.


Hmm.

This ones a bit of a puzzler. Surely the number of channels per pair
[lets just say were talking about copper here] and therefore the cost
to BT is lower on PRI than BRI?

Why the difference? Is this licensing costs from BTs switch supplier
[seems unlikely] or something forced on them by the regulator, or what?

alexd explained on 10/12/2007 :

Absolutely. 8 channels of BRI uses 4 pairs, whereas the same on PRI
would use just 2.

The Wholesale cost of a pair of ISDN2 channels is Ł55 per quarter -
Ł27.50 per channel.

The Wholesale cost of an ISDN30 channel is Ł35.25.

On the flip side, DDIs are cheaper on ISDN30 - Ł0.52 per quarter each,
as opposed to Ł1.09 per quarter on ISDN2e.

The price of installation of 8 ISDN2 channels is approximately the same
as the standard price of 12 ISDN30 channels.



Greed?

As a matter of interest, will they no longer deliver by Microwave?
