old phone phreakers: can anyone tell me exactly what a Watts extender (number) is?

unbelievably, web searches provide near zero results. even usenet has next to nothing.

i saw it referred to *many* times over the years in hacker/phreaker books and articles, but never came across a technical description of how one worked.

by context, its purpose is to extend one's local calling range to long distance without paying for it, but i've never seen an explanation of how it worked.

nostr:npub13levfmuj9uu5gy4mhh0tg5nkujqujkyky8220rd0dkwpm4p950eqss6saf any strong opinions on the Apple 410 plotter? in my year-long quest to find a plotter locally, one came up.

i'm noticing there seems to be a bit of a gauntlet to run in terms of pushing data to it via serial.
