Dan, Slim; I stand corrected!
There is a dos tool for back-up & restore only
for the TA 1232 and there is also a windows based programming tool for the TA 1232.
But only for the TA1232, nothing for the TA624.
Both are from Panasonic direct to their dealers.
My apologies, I really don't do much in the way of analog.
Gem.
