T-Connector
Connections from the cable to network nodes are typically made using
T-connectors, which provide taps for additional runs of coaxial cable to
workstations or network devices. T-connectors, as shown in Figure 4-13, below,
provide three BNC connections, two of which attach to Male BNC connectors on
the cable itself and one of which is used for connection to the Female BNC
connection of a transceiver or Desktop Network Interface Card (DNI or NIC) on a
workstation.

NOTE
T-connectors should be attached directly to the BNC
connectors of Network Interface Cards or other Ethernet
devices. The single solid strand connector of a T-connector
should not be attached to a coaxial jumper cable of any length.
