Ooooooo... the 'DAA' B^} (Sherman, set the Wayback machine...)
In the days before the 'Carterphone' decision, it was illegal to connect
any privately owned equipment to the telephone 'network' without the use
of a 'Data Access Arrangement' which could only be leased (at first,
purchaseable later for mucho $$$) from your 'friendly' local telco.
A nice black box to which you could connect 'approved' equipment, and the
DAA would (supposedly) protect the telephone network from any
indescretions that your equipment might cause.
Following the 'Carterphone' decision, the specifications for DAA like
devices had to be made available to manufacturers of telephony equipment
(witness the little grey box that came with the original Hayes S-100 modem
card), and the rest as they say, is history...
