Notes:
• 0.8 mm 2 fire-rated screened twisted pair cable must not have more than 190nF/km
capacitance or 21
Ω/km resistance.
• 0.2 mm 2
unshielded twisted-pair telephone cable must not have more than 72nF/km
capacitance or 84
Ω/km resistance.
• Between any two connected network nodes, L+ of one node connects to R+ of the
other, and L- connects to R-.
