(True) SONET Specifies framing and multicomplexing at the physical layer of the OSI model.
physical True.
A SONET is a type of network technology layer that is physical. It is used for transporting a lot of traffic over fiber optic cabling.
SONET use RING physical topology and TOKEN logical topology. As simple as that. Logical topology deals with the data transmission. Physical topology deals with how the network is connected physically , BUS, RING, STAR and the like.
The X.25 standard specifies protocols at the Physical, Data Link, and Network Layers of the OSI Model.Broadband Cable functions at both the Physical, and Data Link Layers.ISDN functions at the Physical, Data Link, and Transport Layers.DSL, SONET, and T-Carriers function at the Physical Layer.Frame Relay, and ATM function at the Data Link Layer.
A collapsed sonet ring refers to a ring architecture where the physical fibers used for working and protect both reside in the same physical bundle or buffer tube. The result of this is that typically in the event of a fiber cut, the entire ring will be taken down.
SONET (Synchronous Optical Network) is a physical layer network technology designed to carry large volumes of traffic over relatively long distances on fiber optic cabling.
Sonet Film was created in 1984.
Ishraq Sonet was born in 1987.
SDH = 3 times of SONET
Physical Layer, SONET is the other name used for it
SONET
SONET uses an inverse multiplexing technique called virtual concatenation. SONET, which is the standard used in the United States and most of Europe, stands for Synchronous Optical Network.
