Universal Network Terminal TAU-32M.IP 313
Flow chart
2.
Autoupdate and firmware version check operation algorithm
During TAU-32.IP startup, and upon the expiry of
'Firmware update interval'
timeout or when
'Firmware
update time'
is coming, the gateway checks for the version description file (tau.versions) at the specified path on
TFTP server. If a configuration file is present, then TAU-32.IP downloads it. This file contains information on versions
of firmware files located at TFTP server as well as their paths and names. If versions of firmware located on server
differ from the current ones (used by the gateway), the gateway checks for active call sessions. If there are no active
call sessions, TAU-32M.IP will download firmware files with versions defined in tau.versions file. When download
finishes, the gateway firmware will be updated; otherwise, 10 seconds timeout will be activated. When this timeout
expires, the gateway checks again for active call sessions.
