Question about AT&T Lands Phones
I'd like to upgrade the memory chip in my at&t 1725 answering machine to one
with a larger memory. it uses a non-volatile chip, but i have not opened the unit
to see which one. if someone has the schematics and can email them to me, or
just knows what chip it is, then i could try searching the web to see if i can find a replacement. or, if someone knows that info already, that would be even better. the current chip holds 24 minutes, and i'd like to up that as much as i can. newer answering machines hold about 40 minutes, but are so far either much
harder to use, or lose all settings and messages when the power goes out.
Typically no schematics are ever available for this kind of product as nobody - even the manufacturer - expects to repair them. They are strictly throw-away. But you could open it and try to get the part number from the chip, then search out a suitable larger-capacity replacement. Problem is that almost everything now is surface-mount devices which you probably wouldn't be able to remove and replace without appropriate rework tools. Sad to say, replacement might be the best option.
