CTi Selling Solutions on Layers 1,2,3 & 7- What is the OSI model?
The Open Systems Interconnection Reference Model (OSI Reference Model or OSI Model) is an abstract description for layered communications and computer network protocol design. It was developed as part of the Open Systems Interconnection (OSI) initiative. In its most basic form, it divides network architecture into seven layers which, from top to bottom, are the Application, Presentation, Session, Transport, Network, Data-Link, and Physical Layers. It is therefore often referred to as the OSI Seven Layer Model.
A layer is a collection of conceptually similar functions that provide services to the layer above it and receives service from the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of the path.
The Physical Layer is the first level in the seven-layer OSI model of computer networking. It translates communications requests from the Data Link Layer into hardware-specific operations to effect transmission or reception of electronic signals.
The Physical Layer is a fundamental layer upon which all higher level functions in a network are based. However, due to the plethora of available hardware technologies with widely varying characteristics, this is perhaps the most complex layer in the OSI architecture.
The Physical Layer defines the means of transmitting raw bits rather than logical data packets over a physical link connecting network nodes. The bit stream may be grouped into code words or symbols and converted to a physical signal that is transmitted over a hardware transmission medium. The Physical Layer provides an electrical, mechanical, and procedural interface to the transmission medium. The shapes of the electrical connectors, which frequencies to broadcast on, which modulation scheme to use and similar low-level parameters are specified here.
CTi has many physical layer solutions. Additionally we offer products that test through layers 2 & 3 and that manage IP video in the Applications layer. This breadth of product makes CTi a critical partner in technology deployment.
