Erik, I'm not certain exactly, but I think it must be different types of communications wire for the fullerphone.
Some articles on Ladder wire and DIY wire ww1: Like many aspects of the First World War, cutting wire was an arms race. At the start of the war wire was strung on to wooden posts and knife rests. Under bombardment, shrapnel shells would smash up the wood and blow the wire out of the way.
Also Short ladders are put in place to climb the trenches.
