IEEE 802.9

The 802.9 Working Group of the IEEE 802 networking committee developed standards for integrated voice and data access over existing Category 3 twisted-pair network cable installations. Its major standard was usually known as isoEthernet. The 802.9 Working Group of the IEEE 802 networking committee developed standards for integrated voice and data access over existing Category 3 twisted-pair network cable installations. Its major standard was usually known as isoEthernet. IsoEthernet combines 10 megabits per second Ethernet and 96 64-kilobits per second ISDN 'B' channels. It was originally developed to provide data and voice/video over the same wire without degradation by fixing the amount of bandwidth assigned to the Ethernet and B-channel sides.
