Downloadable Terminal Parameters
The following parameters are downloaded to programmable terminals:
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.
