What does OSI stand for?

All network architectures loosely start with the International Standards Organization (ISO) standard seven layer's Open Systems Interconnection (OSI) model.

Through IP, the migration of analog, digital and network security devices into the tipper layers of the open systems interconnection (OSI) model are creating new dynamics for the cabling infrastructure.

It operates at Layer 2 of the Open Systems Interconnection (OSI) protocol reference model in support of SONET and synchronous digital hierarchy (SDH) transmission standards.

Straight 10-, 100- or 1,000-Mbps media converters operate in the Layer 1 of the open systems interconnection (OSI) model.

ONE's Foundation Product Suite provides Open Systems Interconnection (OSI) protocol solutions, agent development tools, mediation tools, and professional services.

The reference design is a fully functioning Gigabit Ethernet network incorporating a central office optical line terminal (OLT), a customer premises optical networking unit (ONU), optical-fiber transceivers, and a complete networking and management solution for layers 2, 3 and 4 of the Open Systems Interconnection (OSI) model.

The physical layer is the first layer of the open systems interconnection model (OSI), defining the physical and electrical characteristics of the interface to the network, while providing a transparent transmission path for the information across a chosen medium.
