I always understood that if the lights were hung on the same side of the mast (usually right) it was an interlocking signal and if the lights were on opposite sides (left on top) it was a block signal. Interlocking signals also performed block signal functions (to keep following trains apart). Interlocking signals (Canadian rule book, 1962) usually described speeds (restricted, slow, medium or limited) that were to be observed through the interlocking and then the speed to be used to the next signal.
And some RRs used signals to tell the crew which route they would follow through the interlocking.
