How is an exchange LLU'd?

Just curious on how an exchange 30 miles away from the nearest exchange using the same unbundled service is connected to the ISP's backhaul?

Surely they don't run 30-40 miles of fiber to connect it upto the backhaul?

I don't know, but they might just rent raw backhaul off BT.

some use their own network, others rent from BT, some do both depending on the site.

Or one of the other carriers with a national network, Thus, Fibrenet, C&W for example

In some cases yeah, but if we were like America we'd have it running along the electric poles to cut down on costs and speed things up. Though, in Britain everyones a little bit more light fingered

and in the US they often have outages when cars hit poles, or lightning hits the poles. Plus the huge amounts of cable on poles looks unsightly.

The expensive housing estates in the US have all the cabling underground!!

Yuk. I hate seeing overhead cables. I'd rather stick with xDSL than have BT start installing poles and stringing wires across the sky.

What usually happens is LLU companies rent a certain amount of Backhaul capacity from BT to carry the Data to the nearest POP (Point-Of-Presence). The POP is where the data gets transferred from the BT Backhaul onto the LLU ISP's network (If you are on an LLU Service).
