What’s the technical/scientific expalantion behind landline telephones getting crossed?

Question

Im talking about landlines here..I get that a crossed telephone line means a phone number calls someone else but how did that happen? Are there actual wires that used to get crossed?

Answer 1

First lets start with landlines need 2 wires to work. These wires are made of copper. The wires are each individual wrapped in plastic then twisted in pairs. These twisted pairs go into a cable. The cables have connections called splices. When a connection is wet or damaged it gives a chance for the wires to touch other wires in the cable. This gives a short or cross on the line.
