VG-AnyLAN (IEEE 802.12)
The IEEE 802.12 LAN standard defines a different media access control mechanism
as well as a set of cabling specifications for transmitting Ethernet frames
at 100-Mbps over links connected to VG-AnyLAN hubs.
The "VG" stands for "Voice Grade" which means that this system transmits
100-Mbps signals over four-pair (eight wire) copper cables using standard
telephone grade (Category 3) cables. "AnyLAN" means that this system was
designed to transmit data using either IEEE 802.5 token-ring frames or
IEEE 802.3 Ethernet frames.
