a. The "+" and "-" signs represent the polarity of the wires that make up each wire pair.
1000BASE-T
All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use
Assignments straight-through cables for all network connections to PCs, servers, or switches.
The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports
require that all four pairs of wires be connected. Note that for 1000BASE-T
operation, all four pairs of wires are used for both transmit and receive.
