The devices and associated wiring located at a subscriber’s location that connect to a telecommunications service provider’s network are often referred to by a specific term. This equipment can encompass a wide range of items, from simple telephones and routers to more complex systems like private branch exchanges (PBXs) or servers. An example of this would be a modem provided by an internet service provider or the telephone handsets used in an office. Its primary function is to enable the end-user to access and utilize the services provided by the telecommunications company.
The presence and proper functioning of such devices are critical for effective communication and data transfer. Historically, the telephone company owned and maintained much of this equipment, but deregulation and technological advancements have shifted ownership and responsibility towards the customer. This shift has led to increased customer choice and control over their telecommunications infrastructure, allowing them to select devices best suited to their specific needs and budgets.
