This in turn allows the Type-2 PD to discriminate the two-event classification so that it can draw power beyond 13 watts following power-up. In short, the two-event classification serves as a full Type-2 power “grant” from the PSE to the PD. January 21, 2014 Sifos Technologies Page... -

The DC MPS scheme allows for PD’s to drop below 10 mA on a periodic or intermittent basis to save power. A PD that behaves this way may operate below 10mA for up to 250msec out of every 325msec and remain powered by the DC MPS method PSE (see Figure 1.8). January 21, 2014 Sifos Technologies Page... -

Once the trace has been stopped, the binary file will be translated into ASCII text, in a Comma Separated Value (CSV) format. The binary to text translation causes an expansion of approximately 11.8:1. For example, a 10 minute trace accumulated at 6000 bytes/minute would expand to a CSV file approximately 708 kbytes long.
