A long time ago, in a galaxy far, far away - New Jersey, that is to say
- I worked for a company that at the time was called Singer Electronic
Systems. (It changed names two or three times while I worked there. I
don't know who it is now.) We did things similar to this. We regularly
lost people who took jobs at Bell Labs because the skills needed were
similar.
This process of net entry and synchronization is something like what we
do now to sync up both channels of our control. Would you know of any
published material that talks about techniques for net entry - which
isn't classified?
