DP83TC811S-Q1: Questions about cable diagnosis

Hi Team,

As for cable diagnosis, may need to confirm again with you about the following questions:

(1) Can DP83TC811 distinguish the short circuit between the cables TRX+ to TRX-, between TRX+  to GND or between TRX- to GND？

My understand is 811 can't distinguish these three situations. And all these three situation are report as short. Right?

(2) Can DP83TC811 diagnose TRX short circuit to 12V? Whether it could distinguish TRX+ to 12V or TRX- to 12V?

Or actually (2) and (1) are the same, only reported as short, can't be distinguished short to GND/12V?

(3) Whether DP83TC811 can diagnose the open circuit distance of the cable;

Only could be distinguished as open can't tell the distances, right?

(4) Whether DP83TC811 can diagnose the status of LINK-DOWN and LINK-UP;
