Basically ,FMCS we set to 63but if

we want avoid go to F1 we can set

to 64,bcause we need let HS

DSCH Percentage more then 90%

Check CPICH is

normal or not

IIn AXC2.7 version, only 1x AAL2UP VCC is planned. (shared VCC among RT, NRT and HSDPA).

Those sites with VCI=33, set to 25046cps (6xE1) were implemented before April08.

n AXC3.0 version ,dedicated VCC for RT, NRT and HSDPA was proposed.

There are dedicated VC for each taffic:-

VCI=33 is for RT, set to 5000cps ;

VCI=43 is for NRT, set to PCR=25046, MDCR=5000cps

VCI=53 is for HSDPA, set to PCR=25046, MDCR=10095cps

DRA Parameter CheckMaxDLpowerCapability relatedMaxDLpowerCapability 150 (15 dBm) should be for AIR (i think there is only 1 site in thenetwork)

MaxDLpowerCapability 240 (24 dBm) should be for PICOMaxDLpowerCapability 392 (39.2 dBm) should be for Metro8W

MaxDLpowerCapability 421 (42.1 dBm) should be for Metro50W with 2 carrier define in the BTScommissioning file

MaxDLpowerCapability 430 (43 dBm) should be straight forward to be 20W.

MaxDLpowerCapability 457 (45.7 dBm) and 461 (46.1 dBm) should be for Metro50W singlecarrier. I don't know why 2 different value for this.

MaxDLpowerCapability 460 (46 dBm) should be straight forward to be 40W

Another observation, if there is 2 carrier cells define in RNW (carrier 1 is on air and carrier 2blocked), there are 2 type of observation that can be seen:

Carrier 1 cells has MaxDLpowerCapability 460 and carrier 2 cells hasMaxDLpowerCapability 65535, it means that WBTS is only commission with 1 carrier.

Carrier 1 cells has MaxDLpowerCapability 430 and carrier 2 cells hasMaxDLpowerCapability 430, it means that WBTS is already commission with 2 carrier.

What is important is how many carrier are define in the BTS (here i am not talking about theRNW database). If you have 2 carrier, usually the WPA power will be split to 2. So let say if youput a 20 W (WPAB) for a 2 carrier sector, you will see MaxDLpowecapability is 10W. This issomething i observed as well.
