Can any one help to understand why MAX_PDCH causing TCH Congestion.? Below are values that were tuned. Old MAX_PDCH=37, New MAX_PDCH=10 old min_pdch=3, new min_pdch=1 1st August 2012 at 10:52 #68493 Andre CarlosGuest Vendour is ALU with B-11 Release 1st August 2012 at 13:26 #68494 pixGuest the most important paramethater is MAX PDCH HIGH LOAD ! The parameters that can cause TCH Congestion are: MAX PDCH HIGH LOAD MIN PDCH The Max PDCH can be set to a high value, that should not generate TCH Congestion. Indeed, all PDCH located within MAX PDCH HIGH LOAD and MAX PDCH can be quickly preempted by TCH. Are you talking about TCH NA Congestion, or TCH HO Congestion ? TCH HO Congestion might be increased when MAX PDCH is high, but i don’t think so. I’m not sure.
