For the background actions described below, the terminal will be downloaded
automatically if a download retry flag for the terminal is set in software. This flag is
set at the time translation is loaded at boot time, when translation which affects
the parameters of a terminal is changed as part of system administration actions,
and when a port is inserted in software as a result of board insertion or translation
change.
Automatic Download Actions
1. System Reboot/Restart
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.
2. Periodic Tests
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 because it was off-hook at the time
the system first booted or because the terminal was off-hook at the time
translation associated with downloadable parameters was changed.
Note that it may take more than an hour for periodic tests to reach the
terminal that needs to be downloaded.
3. 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 10-128, 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.
4. 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. A digital line circuit pack 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.
