That dates back to the days when it was illegal(?) to
directly connect
any non-Bell equipment to the phone lines. The DAA served to "protect"
the lines from defective or poorly designed third party hardware. (It
also served to fatten Ma Bell's purse!)
Yes, but did the DAA actually do anything in terms of signals? In other
words, what were the specs, and in hindsight, could people have reverse-
engineered the DAA?
