More than likely they won't be able to do a hotswap. The best thing to do is cancel your currently DSL wait until your modem doesn't have Sync with the DSLAM anymore. Then call Cyberonic and order new service. I know it sucks to be with out DSL for that long but the price and value for product is well worth it.
You may want to give Cyberonic a call and ask them if they can do a hot-swap, it might be possible.--
