adchreservation will let you with less available DL CHE for R99 traffic (this creates a mismach between HW installed and licences). As the DL pool is always the less loaded in general this is not an issue but if you have DL HW congestion you could try either to increase the amount of CHE or reduce the reservation (there is a couter that tells you how many adch are you really using). But you will still have the alarm: DownlinkBaseBandPool_DlHwLessThanDlCapacity Subrack=1,DownlinkBaseBandPool=1. But anyway this doesn’t imply a malfunction is just en indication
