Communication Ports
4.2 EoVDSL Ports
Universal and Long-Reach EoVDSL ports (master or slave) must be connected to
EoVDSL ports (slave or master) of the same type. Connection between Universal
EoVDSL ports and Long-Reach EoVDSL ports is not supported. While master/slave
mode can be modified on Universal EoVDSL ports, the operating mode of all Long-
Reach EoVDSL ports is predetermined by hardware. As a result, master/slave mode
cannot be modified on Long-Reach EoVDSL ports.
LEDs
Each EoVDSL port has a Link/Act LED and a Master LED. On devices with Universal
EoVDSL ports, the Master LED can be toggled on or off depending on whether the
port is set to be a Master or Slave. On devices with Long-Reach EoVDSL ports, the
Master LED will be on all the time if the device is set to be the Master, or off if the
device is set to be the Slave.
