packetized data or control information.
layer
ITU-T
A conceptual region that embodies one or more functions between an upper and a lower logicalboundary within a hierarchy of functions
Layer 1 (L1)ITU-T
The layer 1 provides the mechanical, electrical, functional and procedural means to activate, maintain,
and de-activate physical-connections for bit transmission between the data-link-entities. A physicalconnection may involve intermediate open system, each relaying bit transmission within the Layer 1.

The Layer2 provides functional and procedural means for connectionless-mode among networkentities, and for connection-mode for the establishment, maintenance, and release data-linkconnections among network-entities and for the transfer of data-link-service-units. A data-linkconnection is built upon one or several physical-connections. It detects and possibly corrects errors
which may occur in the Layer 1. In addition, it enables the Layer 3 to control the interconnection ofdata-circuits within the Layer 1.
Layer 3 (L3)ITU-T
The Layer 3 provides the functional and procedural means for connectionless-mode or connectionmode transmission among transport-entities and therefore, provides to the transport-entities
independence of routing and relay considerations. It provides the means to establish, maintain, andterminate network-connections between open systems containing communicating application-entities
and the functional and procedural means to exchange network-service-data-units between transportentities over network-connections. It provides to the transport-entities independence from routing andrelay consideration associated with the establishment and operation of a given network-connection.
