From any TSFX's own perspective: Upper phi boundary send 7 bits 1/SL wire-3 to higher phi TSF receive 21 bist 3/SL wire-0,1,2 from higher phi TSF Lower phi boundary send 21 bits 3/SL wire-3,5,6 to lower phi TSF receive 7 bist 1/SL wire-7 from lower phi TSF Upper phi Lower phi 6 |2 |6 2 4| | 4 5 |1 |5 1 7 3| 0 7| 3 0 ---> phi SL3 cell 24 case: Cell 24 is upper phi edge of TSFX2 The failure looks like X2 is missing wire-1 data solidly while wire 0,2 data are getting through sometimes at least. Or, this can be interpreted as problem of X3 sending wire-5 data. X3 cell 25 wire-5 should be local wire-0 of DCH layer 10. According to the DCH->DCT GLINK map, this bit should be word 11 bit 3.
