Assuming here that you are talking about a copper interface: during idle
periods there is no activity (other than link pulses as defined in the
standard).  During data periods on the copper, the data signalling is
Manchester encoded for 10MB and MLT-3 encoded for 100MB.

Kevin

Hi all,

Can anyone tell me,
what is waveform structure for 10 and 100 Mbps Ethernet TX+ and TX-
lines (following 802.3) when node is idle state (not transmitting) and
when it is transmitting. 

Thanks in advance.

Karthik D.
