It is a Dual-NIC !!!

Athlon 1,2GHz ???

You do not like 3Com ?

If you like to offer DSL to your customers, what do you for performance ?
e.g.
Up-Stream Down-Stream
T-DSL 128 kBit 768 kBit
A-DSL 128-860 kBit 1,5-6 Mbit
S-SDL 1536 kBit 1536 kBit
Cabel-Modem 128kBit - 2MBit 2 -30 MBit
Wave-Lan 64/128/256/384/512 kBit and unlimited 11 MBit
How many Clients Du you need or like to have ???
If you are ISDN-Access-Provider you have around 100-150 Clienst per MBit
and Crazzy ISP's 250 Clienst per MBit.
Because the speed of my FunkLAN with 512 kBit for each client I calculate
a maximum of 50 clients (home users) per MBit and 20 clients per MBit for
proffessional users.
I like to get 10% of all housholds in Kehl.
And I must calculate with 870 home users and I need 17.4 Mbit
Now I must calculate around 100 proffessional users and I need 5 MBit.
Then I must have a reserve vor my own Servers (virtual-Web-Servers,
pop3, ...) and my Online-Store-Server.
So I need a minimum of 34 MBit and the base price is 4990 DM/month
The smaller solution ist 2 MBit but you pay 1890 DM/month
And then you must pay the Traffic which is around 56 DM/GByte
I think, multiple 2 MBit lines are too expensive
