done : changed to
span=1,1,0,ccs,ami
span=2,0,0,ccs,ami

(if my memory is ok, port 1 is set to NT mode, port 2 is to TE.
I'm still wondering how to teach to port 2 to use timing from port 1 (I
think span=2,0 means that but 'm not certain) and above all, how to teach
port 1 use a timing source elsewhere and use it)

b410 manual says pins are affected this way :

3   Tx+ (TE)   Rx+ (NT)
4   Rx+(TE)    Tx+ (NT)
5   Rx-(TE)    Tx- (NT)
6   Tx- (TE)   Rx- (NT)

I don't know if this means a straight cable is ok or not.
If someone could shed some light ...
