Reply To: SDCCH dimensioning for HR environment



In Alcatel BSS, the SDCCH failure rate threshold is 20%.

Below 20% : it is good.

Subscribers will not “feel” anything wrong with your network, it is a perfectly normal network.

Trust me.

Now, you have to check the SDCCH Preparation Failure due to Congestion. If that is higher than 2% or 3% (at busy hour), then you have SDCCH congestion problems.
