So….
How many idle TS should be set properly? Idle TS Needed =
Next …
Why 3? Because we need to utilize for 1 PDCH to get 64 k Why don't we set 4? Because 1 PDCH or TS in TRX (radio) is 16 kbps Then, by multiplying with 3, 1 Abis Ts 64 kbps wi Remember 1 Idle TS is 16 kbps in Abis
Next..
If only 81 Idle TS, can we add additional idle TS? Yes, the maximum is as calculated by Nexwave's RSL Timeslot is calculated from max TRX (12)/2 = So the maximum is only 139, as depicted on the f
Notice : query of this counter is per E1, but 1 E1 only has Well, this probably due to Occupancy sharing implement Perhaps, there should be a counter which shows occupa
So.. Can we say that Abis Utilization for PS is : If 1 E1 ==> (Occupancy TS/128) * 100 If 2 E1 ==> (Occupancy TS/256) *100 Well, I'm not sure about this formula, but E1 is for throug

Question 1
270
What happen if I put Max PDCH rate =30%?
271
What happen if I put Max PDCH rate =40%?
272
What happen if I put Max PDCH rate =30%?
Meaning of MAX PDCH Rate = Number of available PDCHs/(Number of available TCHFs + Number of available static PDCHs). This parameter is used to restrict the PDCH ratio
team (1 site) = Sum PDCH + TCH Nexwave where ROUNDUP(0.3*K15,0), is only applied where max PDCH Rate of all sectors ar all sectors is 30%, then ==> sec-1 (30%*26) + sec-3 (30%*26) + sec-3(30%*29) = 24.3 (round u max PDCH rate which is as set as the existing (30/40/30) each sector, I'll get sec-1 (30%*26) +
e set properly? 27 * 3 =

or 1 PDCH to get 64 kbps in Abis TS.
RX (radio) is 16 kbps (actually 13, but pluse header, etc) 1 Abis Ts 64 kbps will be assigned properly. bps in Abis
d additional idle TS? culated by Nexwave's formula which only depend on Nb of E1, Nb of PDCH + TCH, and Nb of rom max TRX (12)/2 = 6 , as depicted on the figure below
per E1, but 1 E1 only has 128 Idle TS? How Come in 2nd E1, the number is exceeded above 128??? ancy sharing implemented by Huawei equipment itself. As point of view, this can make a confusion (let say i er which shows occupancy of Abis, not only per E1.
ion for PS is : Before Add E1 (Red Line), max Utilization of Abis is (128/128)*100 = 100% After Add E1 (use Blue Line), max Utilization of Abis is (139/256)*100 = 54%
ula, but E1 is for throughput purpose.

Answer 1
Question 2
If 30%, then ==> 30% * 26 = 7.8 (Round up to 8), which mean 10 PDCHs we've set is not utilized optimally, we can say, that sector 1 can oly utilized 8 PDCHs at the same time
Next, so what's the relation with value 38.46%?
If 40%, then ==> 40% * 26 = 10.4 (Round up to 11), which mean 8 PDCHs we've set will be have extended 3 PDCHs from TCH full rate at the same time of occupation
Next, so what's the relation with value 30.77%?
If 30%, then ==> 30% * 29 = 8.7 (Round up to 9), which mean 4 PDCHs we've set will be have extended 5 PDCHs from TCH full rate at the same time of occupation
Next, so what's the relation with value 13.79%?
e of all sectors are the same, if not, then you have to calculate per sector 9) = 24.3 (round up). This Value is as same as by that of Nexwave's formula (See L15) t sec-1 (30%*26) + sec-2 (40%*26) + sec-3 (30%*26) = 7.8 + 10.4 + 8.7 = 26.9 (round up 27)
TCH, and Nb of RSL Timeslot

Answer 2
This means that if I want to utilize as many as 10 PDCHs as I set on the TRX channel, I have to set SET GCELLPSCHM Max PDCH Rate=38.46
This means that if I want to utilize as many as 8 PDCHs as I set on the TRX channel, I have to set SET GCELLPSCHM Max PDCH Rate=30.77 This means that if I want to utilize as many as 4 PDCHs as I set on the TRX channel, I have to set SET GCELLPSCHM Max PDCH Rate=13.79
