I seem to remember when the wings were built the cables were simply buried wire cables and sometimes farmers would cut them. When I left Minot in 1972 CDB was something that was going to be the next upgrade after the Mod. We understood it would let the crews change targeting info from the LCC.
All the cable systems were not just buried wires. The actual wiring was encased in a tube that was kept pressurized with air from compressors at the LCFs. If a cable was cut or something intruded into the casing there would be a cable pressure alarm.
Also, the A systems used redundant cables that ran to the LFs so if one was cut or destroyed there were others to keep connectivity.
The B system used a single cable run from the controlling LCC to each LF and from LCC to LCC, and then a Medium Frequency Radio was used as the backup. The problem with the MF Radio was when thunderstorms rolled through the missile field the Deucers were kept up sweating LF Down, LFDN, printouts. When one capsule was down for maintenance there was a cable break within the squadron and then some of the LCCs could only see some LFs via radio. Thus, when the radio was interfered with by the weather capsules would see the LFDN print and have to respond to ensure the missile was seen by the others. A 328 printout (UHF Mode) was a career killer if it was determiined there was a way to stop it from happening.
The Deuce capsules were roomy but my old Titan II LCCs were the best: Bedrooms, showers and a full kitchen!
