Orderwire provides private system voice and data maintenance communications network that works on a Party-Line concept utilizing a portion of system spectrum not normally available for revenue traffic. By employing four-wire circuit devices, the orderwire allows multiple-party conferencing without the need for special conference devices. Orderwire networks can interface the Public Switch Telephone Network via off-net circuits to bring communications workers directly in contact with other maintenance personnel not on the orderwire system. The Orderwire looks like an ordinary telephone and can be connected to a normal communications channel or a special supervisory channel or port.

Orderwire networks can be formed into hubs and isolated sections utilizing multi-channel OrderWire and cut-through switches. OrderWire is a true party-line system. It requires no central switching. Any specific station may be called.
