A telecommunications closet (TC) is a small room that encloses telecommunications network systems and devices. This closet is the central junction point for all wiring equipment and wiring for devices connected in the local area network. It often contains access to wiring conduits large enough for service personnel to access in order to service or install cabling networks within buildings.
A telecommunications closet is also known as a wiring closet.

The telecommunications closet plays a critical role in networking as it connects the IT infrastructure with the end users. It helps in keeping track of wires, storing hardware and helps in making hardware changes to the devices in the network easier and simplified. It also helps in identifying unnecessary connections and devices in network and thus avoids the clutter in the large network topology.
