PRODUCTION DATA
When operating in 10BASE-Te or 100Base-T mode, signals can be looped back at the RJ-45 connector by wiring the transmit pins to the receive pins. Due to the nature of the signaling in 1000Base-T mode, this type of external loopback is not supported. Analog loopback provides a way to loop data back in the analog circuitry when operating in 1000Base-T mode.
