B1_DD+/-
Gigabit Ethernet Controller 0 activity indicator, active low.
Gigabit Ethernet Controller 0 link indicator, active low.
Gigabit Ethernet Controller 0 100Mbit/sec link indicator, active low.
Gigabit Ethernet Controller 0 1000Mbit/sec link indicator, active low.
Reference voltage for Carrier Board Ethernet channel 1 and 2 magnetics
center tap. The reference voltage is determined by the requirements of the
Module PHY and may be as low as 0V and as high as 3.3V. The reference
voltage output shall be current limited on the Module. In the case in which
the reference is shorted to ground, the current shall be 250 mA or less.
