time to build a telephone exchange at home....
I have one - it has two lines. It was a product we sold after bisync
and SNA emulator sales tanked. There's an 8048 MCU inside, along with
two "SLIC"s (Subscriber Line ICs). The 8048 listens to DTMF tones and
provides various simulated faults or a solid connection based on the
number you dialed. [...]
As for a simple simulation at home, a 6VDC to 24VDC loop might be
enough to pull it off, though some devices won't know to pick up
unless you simulate an AC ring.
