ISND as backup to point to point lease line

[utawakevou]

Our telco company here in Fiji has launch their ISND services this week. We are interested in having ISDN dial backup for some of our critical sites.

Would appreciate if someone could show me some configuration example.

Thanks

ISDN dial backup can be very effective. Not only is the data rate higher than analog, but the call setup takes only a few seconds, minimizing down time.

In addition to the examples on www.cisco.com, there are a quite a few dial backup sample configurations taken from my book (High Availability Networking with Cisco) on my web site (www.networkingunlimited.com). Of course you'll need to buy the book to get the explanation of how they work :-), then again, you might find that the two dial backup whitepapers there are all you need.
