Signal loss is present more in digital cable due to the distance,more the distance high the signal loss hence the repeaters are used to minimise the loss. Incase if one of the repeaters fail, then it is also a big headache for consumers as well as wire is cut.
But here if the repeater fails or needs replacement the cost is incurred by LCO, and the subscriber doesn't need to do anything. Normally the repeaters and amplifiers are changed before hand so that they don't malfunction. it depends on area to area.
In case of DTH LBN faults or dish change, alignment the cost is incurred by subscriber.
