Know the Parts of the Diagram

Before you can begin to understand a landline phone wiring diagram, it's important to know the various parts of the diagram. A typical landline phone wiring diagram will include the following sections:

Reading the Diagram

Once you've identified all the parts of the diagram, it's time to start reading it. When reading a landline phone wiring diagram, it's important to look at the colors of the lines. Each color corresponds to a specific telephone line. For example, red may represent the local line, while blue may represent the long distance line.
