Manual Telephone Central Office

Manual Telephone Central Office is a type of telephone exchange that is operated manually by human operators. It is a part of the supply class Telephone And Telegraph Equipment, which falls under the supply group Communication, Detection, And Coherent Radiation Equipment.

A Manual Telephone Central Office is responsible for connecting telephone calls between different subscribers within a local area. It consists of a physical location where telephone lines are terminated and connected to the appropriate destination. The operators at the central office manually establish and disconnect calls by plugging and unplugging cables.

These central offices were commonly used in the early days of telephone systems when automation was not yet available. However, with advancements in technology, manual central offices have been largely replaced by automated systems.
