It's not hard, it's complex. I spent a few years going through 834 and later at a different company, 811. For the first I embedded a javascript interpreter to do translations. For the second I put most of the logic in the code.

There is still a lot of it in service. Sometimes you'll see a tank of nitrogen chained to a pole. It is there to put pressure through the cable to keep water out of a cut/nick on the lead sheath. The lines are pressurized normally from the central office and if the monitoring shows a drop in pressure (a cut in the sheath), they roll out cable maintenance.
