oh this sounds so familiar to me.
got a Siemens hicom 300e here and had the same problem.
I had a DB15 connector and when I got mad that it wasn't working like it was 
specified I cracked the connector open and found a weird non standard wiring 
from rj45 to db15. I twisted the wires like they were supposed to but then 
this blinking problem of yours occured to me and it vanished when I told 
Hicom to be the master of the line and * the slave.
As from that point I got some minor errors in d-channel protocol which seem 
not to interfere with operational service although the d-channel went done 
for once for no obvious reason.
