6 Avaya MultiVantage Software-Controlled Maintenance:

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: 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 that cause a terminal to be downloaded. These can occur as part
of background maintenance activity or on demand from the 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 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 the previous
Table 18, these changes can be for a specified terminal or may be system-wide. If the change is
