We are using CS11's and had wires running all over this single
story building. On one multicore (across the flat roof) we lost
two tty lines.  Now the problem is.. how do you get the
distribution panel PCB's apart to service the line components?
It looks a fairly final (terminal?!) assembly to me.  Our
"after the lightning has bolted" solution was to install a low
cost RF carrier packet system using a cheap TV co-ax ring.
This places yet another (and more serviceable) box between Thor
and the Unibus.  Oh yes.. and we got the cables down off the
roof.
