[BC] unreliable old equipment query

Since I've never worked in television, I can only speak as a viewer.
Starting in the early 50s, I can recall a few times when there was a 
total off-air resulting in snow and white noise,  and a few projector 
jam-ups which usually got fixed in a matter of minutes.
But the worst was the infamous program loss and the slide which said 
CABLE TROUBLE.  Sometimes there would still be audio but no picture. 
These cable trouble incidents would usually last for quite some time, 
often the better part of an hour, while the techs at AT&T or whatever 
their carrier was, got network video restored.   Much rarer were the 
times when only the audio failed.
How often the cable trouble slide was used when there was actually some 
local  studio problem; I obviously can't say...........

P. S.: WCOS-TV was the first TV station to get on the air in SC, in 
1953. It only lasted ~three years; one of the main contributing factors 
to its demise was that it cost  $ 1500 every month in 1953/4/5/6 dollars 
to get the network from AT&T downtown to the station. (IIRC, $1500 would 
buy a medium priced car back then.)  Another form of cable trouble, you 
could say.
