It is a stored program control call handling system= designed to respond to calls with potential forwarding or disconnection me= ssages. Reading through the description of the operating system for AIS go= t me wondering: What with the growing experience in the CSRC regarding kernel technologies = and systems programming, was there ever any crossover regarding UNIX folks = applying their developments to other non-UNIX AT&T systems projects or vice= versa, perhaps folks who worked primarily on switching and support softwar= e bringing things over to the UNIX development camp? In other words, was t= here personnel cross-pollination between Bell System UNIX programmers and t= he folks working on stuff like AIS, ESS switching software, etc.? Or were = the aims and implementation of such projects so different that the resource= s were relatively siloed? I would imagine some of these projects were at least developed using UNIX g= iven the popularity and demands of PWB. That's just my hunch though, some = BSTJs also describe software development and maintenance taking place on S/= 360 and S/370 machines and various PDPs. Indeed the development process fo= r AIS mentioned above, as of late 1971, involved assembly via S/360 softwar= e and then system maintenance and debugging via an attached PDP-9. =20 - Matt G.
