Not very common to use two different providers with one as a backup provider. Although I'm a little surprised that they haven't looked at getting a wireless provider to provide a link as well (faster and I would imagine cheaper than ISDN, and telstra do offer wireless services as I have used them once before to get an office up and running prior to the installation of a cable). If wireless goes down, you have the cable, if the cable goes down you have the wireless....
Its a common misconception that by going with an alternate technology or provider you have a backup, most of the wireless terminates into the network at the same location as the DSL, and if you buy a second DSL of say Internode or any of the other carriers you could find your self on the same fibre link out of the exchange as your telstra service, if that gets cut you loose wireless and all the DSL as well as frame relay, ethernet and ISDN services. A good example of this was the loss of Optus backhaul links from Brisbane last year, many other ISPs were affected including wireless services from other carriers, as they used the same backhaul, the only difference was the media used for the last mile connection.
