If the cellular connection fails in Cellular modem preferred (PRISM) mode
In Cellular modem preferred (PRISM) mode, link selection is handled by the PRISM client in the
EXPLORER 540 - it will always use the primary link (cellular) if it is available. If the primary link
goes down or if ping fails, it will switch to the secondary link (BGAN). As link switch-over does
not interrupt the data stream, it will switch back to the primary link as soon as it is available
again (Link failure or link monitoring failure will require a new authentication phase).
