server, the AT-VP504E FXS tries to initiate the software
download with the secondary software server.

software server, the AT-VP504E FXS idles for one (1)
minute.
4. After this one (1) minute, the AT-VP504E FXS retries to
initiate the software download.
5. If the software download fails again with the primary and
secondary software server, the AT-VP504E FXS idles for two
(2) minutes before trying to initiate the software download.
6. If the emergency software download still fails, the
AT-VP504E FXS retries to initiate the software download by
