Automatic Download Actions
This section describes download actions that occur automatically.
System Reboot/Restart
DIG-LINE (Digital Line)
A global download action is started when periodic maintenance tests start after a system
reboot/restart regardless of whether the parameters have been downloaded previously.
Periodic Tests
Note: It
If the download flag is still set when periodic tests are run on a terminal, a download action
will occur. This operation is required in case a terminal could not be downloaded
previously either:
● Because it was off-hook at the time the system first booted
● Because the terminal was off-hook at the time translation associated with
downloadable parameters was changed
Note:
may take more than 1 hour for periodic tests to reach the terminal that needs to
be downloaded.
Terminal Administration
A downloadable terminal is automatically downloaded when translation changes
associated with downloadable parameters are made as part of system administration. As
shown in Table 85: Parameters Downloadable to Programmable Terminals, these
changes can be for a specified terminal or may be system-wide. If the change is for
system-level parameter, a background global update request is made to download all
programmable terminals.
This global update may take more than an hour for a system with several thousand
programmable terminals.
Port Insertion
Whenever maintenance software initiates a request to place a port into service, a terminal
download action is started on that terminal if that terminal is programmable. This port
insertion action occurs under the following circumstances:
● A digital line circuit pack or media module that is physically inserted into the system
has ports currently administered for programmable terminals.
If more than 20 port insertion requests are received within a few seconds, a global
download request is started up as a background task. This action updates all
programmable terminals instead of just those being inserted. This is done to avoid
system overload for situations where there is massive board insertion. This could
occur when connectivity to an PN is re-established after that PN was down.
● A station port is added to the system by add station or change station.
● A TTI port is activated.
