Nonvolatile Memory
Nonvolatile memory stores downloadable parameters in programmable terminals. Once the
terminal is downloaded, it is not be necessary to download it again, even if power is removed
from the terminal. If nonvolatile memory fails with power still present, the terminal reverts to its
default factory settings except for its A-law/mu-law companding settings which are stored in
RAM. If power is removed after the nonvolatile memory fails, the terminal reverts to its factory
default settings.
Note:
Note: The mu-law companding mode is assigned as a default setting at the factory. For
the United States, a programmable terminal can place calls even though it has
not been downloaded from the system.
Download Actions
There are several different scenarios which causes a terminal to be downloaded. These can
occur as part of background maintenance activity or on demand from the SAT (System Access
Terminal) or from a station.
For the background actions described below, the terminal downloads 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 the translation that affects the parameters of a terminal is changed as
part of system administration actions, or 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 initiated when periodic maintenance tests begin 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
occurs. This action is required in case a terminal could not be downloaded previously,
because the terminal was off-hook when the:
● system first booted
or
● translations associated with downloadable parameters were changed.
Note:
Note: It may take more than an hour for periodic tests to reach the terminal that needs
to be downloaded.
