Per the 802.3cg spec the 10base T1L can operate at 2 different differential voltages 1v p2p and 2.4v p2p. The abiility of the PHY to drive that output is dependent on the PHY's on board power supply. This common feature is applicable to all 10base T1L PHYs so this binding property belongs in a top level ethernet document.
