Automatic Download Actions
This section describes download actions that occur automatically.
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 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:
Note that it may take more than 1 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 8-218 on page 8-540 , 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. This could occur
when connectivity to an PN is re-established after that PN was
down.
b. A station port is added to the system by an add station or change
station command.
c. A TTI port is activated.
