Netcomm NCT240 Manuel D’Utilisation

 

IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3, 4, or 5 UTP cable. 

IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 UTP cable. 

IEEE 802.3u specification for 100 Mbps Fast Ethernet over two strands of 50/125, 62.5/125 or 

9/125 micron core fiber cable. 

IEEE 802.3ab specification for Gigabit Ethernet over 100-ohm Category 5 or 5e twisted-pair 

cable (using all four wire pairs). 

Signaling method allowing each node to select its optimum operational mode (e.g., 10 Mbps 

or 100 Mbps and half or full duplex) based on the capability of the node to which it is 

connected. 

The difference between the highest and lowest frequencies available for network signals. 

Also synonymous with wire speed, the actual speed of the data transmission along the cable. 

A condition in which packets transmitted over the cable interferes with each other. Their 

interference makes both signals unintelligible. 

Single CSMA/CD LAN segment. 

CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication method 

employed by Ethernet, Fast Ethernet, or Gigabit Ethernet. 

A workstation, server, or other device that does not forward traffic. 

A network communication system developed and standardized by DEC, Intel, and Xerox, 

using baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. The 

successor IEEE 802.3 standard provides for integration into the OSI model and extends the 

physical layer and media with repeaters and implementations that operate on fiber, thin 

coax and twisted-pair cable. 

A 100 Mbps network communication system based on Ethernet and the CSMA/CD access 

method.
