An extension telephone is an additional telephone wired to the same telephone line as another. In middle 20th century telephone jargon, the first telephone on a line was a Main Station and subsequent ones Extensions . Such extension phones allow making or receiving calls in different rooms, for example in a home. Some telephones intended for use as extensions have built in intercom features. A telephone extension is an internal telephone line attached to a Private branch exchange PBX or Centrex system. The PBX operates much as a community switchboard does for a geographic telephone numbering plan and allows multiple lines inside the office to connect without each phone requiring a separate outside line. In these systems, a dialer usually has to dial a number typically 9 in North America, 0 in Europe to tell the PBX to connect with a landline also called DDCO, or em Direct Dial Central Office em to dial an external number. Within the PBX, the user merely dials the extension number of the person. Each phone line may be extended up to a fixed maximum. Reasons to use extensions Since not all users dial out at the same time, sharing trunking trunk lines is cheaper than giving each phone its own private landline. ref Newton, H Newton s telecom dictionary , page 901.
