G.8264
An ITU-T standard specifying the Synchronization Status Message (SSM) format for Synchronous Etherent.
Gateway
Gateways are points of entrance and exit from a communications network. Viewed as a physical entity, a gateway is that node that translates between two otherwise incompatible networks or network segments. Gateways perform code and protocol conversion to facilitate traffic between data highways of differing architecture.
Gigabit Ethernet
Gigabit Ethernet, also known as GbE, refers to a transmission rate of 1 Gigabit per second (1,000 Megabit per second) using Ethernet technology. Various Gigabit Etherent standards address GbE transmission over different fiber and copper media. Initially deployed in the LAN, Gigabit Ethernet is now a standard interface for WAN access to Metro Ethernet networks.
Gigabit Ethernet Converters
Gigabit Ethernet converters typically link copper cabling (UTP) with fiber optics or multimode fiber with single-mode fiber cables, to enable transport of Gigabit Ethernet traffic over diverse media.
GUI
Graphical User Interface
Pronounced “gooey,” this software interface is based on pictorial representations and menus of operations and files. Opposite of command line interface.
