Re: An E1 line - how does it work?

The speed of an E1 link is 2Mb.
Yes, I know, and I still don't get your point.
It seems fairly obvious to me that not only do/did you (obviously) know, but that the OP did so before posting. So you answered the OP's question without giving him redundant information smile.

So I don't get the point of that other post either.

If out of limts for copper delivery (1,2 or 3 pairs) then either fibre, or 18ghz radio assuming their is line of sight, planning permission, costs etc.

Ok thanks for that.

Never worked for BT so can only describe what 'A N Other' operators did!

Yes I know this and am quite familiar with them, have assisted in commissioning a few. Over the kind of distance the OP mentioned though, with DSL circuits indicating a loop length of >4km, doesn't this seem a bit of a stretch for 2 pairs? Without a line extension / regeneration E1s max out around 3km.

E1s are often delivered via SHDSL and HDSL. The cable companies come to mind immediately as two who delivered this way, fibre to cabinet then SHDSL or HDSL if multiple pairs are needed.

The point of running with EFM is to supply resiliency and remove the need for a repeater. Even over that range they can rack some pairs up to deliver 2Mbps reliably using SHDSL.bis.
Okay I have a little more information. We've apparently been quoted around £4,000 (it's only me doesn't know the exact figure - IT have formal quote from the provider). So how much work can be done for £4,000 given this route:

It's the smaller of the two green objects. The larger one appears to be an electricity engineer laugh

Optician time for you melad!

The larger one is a milkman, and his float is on the opposite corner.

ROFL! Yeah - you can even see the bottles in his hand.

My excuse is that I've spent most of the week working and fighting with NetBackup smile

It would certainly explain why he's 'putting his best foot forward'. I did think it was a little odd that someone of that ilk would be going anywhere in such a rapid and determined manner laugh
