Laying out the system
• Cable
Use twisted pair cable 1.0-1.2mm dia., 18 - 16AWG for trunkage line. If it contains extra pairs,
those must be terminated with a 120 Q resistor at both ends. As to individual call wires, use the
same but separately jacketed twisted pair cable, in which unused pairs may remain unterminated
