The survivable core server performs a reset system 4 when it no longer controls a Media Gateway. The reset system 4 command is used to clear alarms, busyouts and allow any pending translations to be loaded.
Note:
It is possible to perform a file sync (translation download) from the main server to the survivable core server while the survivable core server is controlling one or more Media Gateway. The translations are received by the survivable core server but are not loaded as long as the survivable core server controls a Media Gateways. Once the survivable core server no longer controls a Media Gateway, the survivable core server resets and loads the new translations.
