Hi all

we are looking at the options for a backup circuit to our primary 2 meg e1 connection.

the options we are looking at are, 4 isdn lines, vpn over a business broadband circuit, or vpn over sdsl circuit.

can anyone suggest the best ot use here ?

cheers

If you go with the ISDN then it will be more preferable.

8x 64 Kbps ISDN?

VPNs over Internet?

Broadband bandwidth, up and down? Any SLA?

SDSL bandwidth? Any SLA?

I would suggest ISDN.

Hi,

Is that real time traffic? If yes, then go for "ISDN PRI" for backup circuit to your primary 2 meg e1 connection. It's enough to carry the payload of your traffic.

Thanks

hi,Carl

if isdn is choosed,

you only need to pay for isdn when the primary link down and isdn become up.
