Wire and Cable manufacturers have historically put a single insulated communication conductor (22 or 24 ga) in multipair instrument cables to allow installers at each end to talk to each other by telephone handset during installation. They used the communication conductor and a drain to complete the circuit. Is this still used or has wireless radio communication taken over? I would like feedback from installers on what is actually used and whether the communication wire still has value.
