Reply To: High SDCCH Fail on VSAT cells


thanks for the calculations 🙂 i put these settings on a VSAT cell, but it didn’t change anything. It looks like 1.5s is still too short for the reply. But wait a second… the value for S cannot be as big as 217, can it ??

And anyway, you’re right. The problem lies on the RACH repetition on the air interface. The channel request will then be transmitted on the abis interface. So your proposition is 100% valid !

But conclusion is still the same : for VSAT cells in Alcatel systems, a SAFR radio = 50% is N.O.R.M.A.L.

It’s not my conclusion, tests have been done by TAC. it’s worldwidely accepted.
