Hi Ristre,
I just found this rule to be checked :
T_GSL_Ack (BSC) > T200 (GSL) * (1 + N200 (GSL))
N200_GSL (BSC) : Maximum number of re-transmissions on a GSL link.
T_GSL_ACK (MFS) : Supervision of MFS acknowledgements on BSCGP.
T200_GSL : Supervision of acknowledgements on the GSL link.
Regards,
Pix
