1.5 STANDARDS
The physical and electrical characteristics of the Token Ring module
conform to the IEEE 802.5 standard. The protocol for the MAC layer is
specified by the IEEE 802.5 standard while that for the Logical Link
Layer is specified by the IEEE 802.2.

1.6 CONNECTORS
The Token Ring modules are available in versions for either UTP or STP
lobe cabling. The STP version of the four port Token Ring module has
four DB9 connectors; the UTP version has four RJ45 connectors. Power
for the module is provided by the ATX backplane.
