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?

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
