Best Backup Solution for WAN

[bbravo]

What is the best -according to you- failover WAN solution for hub-and-spoke design network, the central office and all the other sites (10 total) will be within 50 miles, has anyone been faced with same decision making issue? Primary circuits will be PPP T1's, what about the secondaries? Thanks much in advance!

If you can afford other dedicated T1s, of course use T1s. If you can't afford T1s, use dial on demand, for example ISDN(BRI/PRI). You really need to assess the amount of data that need to be sent over the backup link.
