In germany I have payed for a Redunant E3 at UUnet around
10.000 Euro/month and then the traffic :-/ around 25.000 Euro/month.
Oh yes, In Germany You get the Acces realy cheap,
but you pay for the traffic !

Yes, but you can only use 4 Channels paralel of the 19.

The 54 MBit are only Theory !
Practical you can get around 40 MBit for each channel.
So if I install for example 4 Channels in Casablance I
have around 40% of all resources there !
But, if I calculate with 5-6 E3-Links and 42.000 Euro per Link,
I will necer earn money with it !

I have friend in Marocco for more then 23 years, and I have
done there very much, NOW the are thinkin, I can do ALL !!!
Generaly right, but I need enough time for learning
Curently I am preparing only a study about this project and
its possibility. I think realy it can be done...

It depends, because
1) If I have only a NetworkCenter (4 x OC-3) for my CyberCenter
project, I need only RadioBridges which supports E1, E2 and
E3 and OC-3
2) If I support paralel to 1) commercial Users (End and ISP), I
need a bigger Backbone like 2 x 1 GBit which mean, I need
GBit RadioBridges maybe up to 1,8 GBit too.
The price is realy heavy (around 27.000 US$ each ) and they
support not more the 20km and you need many Briges...
What I need is a study about installing wired !
Dont know the price for the special cable, the Repeaters, ...

I was thinking about minimum two independant and 100% redunant ISP's.
OK, I have already 26 Server prepared, but it is only for the
CyberCenter and can support up to 100.000 customers .
Bigger Backbone need bigger Servers...
So 100 MBit FullDuplex will not enough.

You mean via Satelit ?
I have read an Documentation that one Satelit Link can support
up to 50 MBit. Is this right ?
But there are already concurence: <http://www.directsky.net/>

I can use the Proxim Tsunami MP.11a which sopports with the
Outdoor Router Software upgrade Traffic Shaping from 64 kBit
to some MBit (do not know exactly)
