   What did you change on the DSLAM? That could be why you   
   are having trouble now, since the trouble seemed to happen immediately   
   afterwards.   
      
   What country are you in?   
   Zyxel has support in quite a few countries. Why don't you try   
   contacting them (in your native language.)
