Liityntäkohtaa

Liityntäkohtaa is a Finnish term referring to a junction or attachment point where different parts of a system meet and connect. The word is formed from liittää (to attach) and kohta (point) and is used in technical and industrial contexts to describe where interfaces, components, or networks come together.

A liityntäkohta is typically a physical or logical interface that enables connection, transfer, or interoperability between subsystems, networks, or devices. It can be a demarcation point in service provisioning between a customer and a service provider, an interface where a building’s installation connects to a utility network, or a junction within a transportation, energy, or data system.

Contexts where the term is common include telecommunications and information networks, where it may denote the point at which subscriber equipment connects to the provider’s network; energy and utilities, where it describes the connection to electricity or district heating networks; and civil engineering or transportation, where road, rail, or pipeline connections form important liityntäkohtia. In manufacturing and systems engineering, it can refer to the interface between modular components. In software and IT, the term can be used metaphorically to describe integration points between systems or APIs.

Design and management aspects often associated with a liityntäkohtaa include the specification of interfaces (mechanical, electrical, signaling), safety and reliability requirements, accessibility for maintenance, and proper documentation in drawings, contracts, or network diagrams. Standards and regulatory considerations may govern compatibility, testing, and verification of these connection points. See also liitäntä and rajapinta.
