olemus
OSI mudeli 1. kiht, toetab liidestust
füüsilise edastusmeediumiga, määrab näiteks
- lülikihi bittide paigutuse liidesepistmiku kontaktidel
- signaalide kodeerimise ja konverteerimise
- bitivoo reguleerimise
- kandja tuvastuse ja põrgete lahendamise
- veatõrje
- kommuteerimise ja multipleksimise
= Layer 1 of the OSI model, supports interfacing with a physical transmission medium

ISO/IEC 2382-26:
kiht, mis annab bittide edastusmeediumi kaudu teisalduseks
vajalike füüsiliste ühenduste loomise, käigushoiu ja lahutamise mehaanilised, elektrilised, funktsionaalsed
ja protseduurilised vahendid
= the layer that provides the mechanical, electrical, functional, and procedural means to establish, maintain and release physical connections for transfer of bits over a transmission medium
