hi mohit,
o/p power in nolkia bts is 20 watts and 43 db,power in db=10 log(p in watts).now note that for every 3db change power in watts will be twice i.e power in dbm=10 log(1000*p in watts),trx power is always equal to all bts emit power i.e 20 watts in ultra site bts and 40 watts in metro site bts,kindly mail me if any more queries
mohit kindly consider those in dbm, it ws miswritten, 20 w=43 dbm
except nokia what about output power and dbm for other bts like nortel etc.,
hi siva, u shld see the manual for this of nortel or other equipments, wt power o/p they claim to customer,so itis vendor dependent,bt normally it is 43dbm
hello hasan ji

Hi I am working in Nokia System support team Pune.
I have one querry regarding DAC value. First of all the meanin g of the same its desired values to be set.
The drift inthis value is given by the alarm “difference between PCM and base station frequency reference”
Now if 3/4 of the sites in 1 BSC are having this alarm should there be any common reason?
Hello:
Jayesh: It could be a transmission problem have you check if there is a common path?
Madhav: the alarm configuration for ultrasite is made from the BSC using the EFX command, I thik is the same with the metrosite.
Best regards
Hi siva

ramajayam_ch@yahoo.comHello Price of Finland,]
pls help me to clear alarm history in Flexi Hopper IDU. also tell me about the script tool, give some examples.
can we see the farend Rx level in FH IDU at near end if we use RRI in far end..GEO. Kerala – 2 Oct 2006
You can see FAR END but you must have this good version of software.(to see alarm, rssi, change tx power ,…)
check this: maintenance – software – view.
program ID, CHECK Active version.
The more indice is high, the more is better.
ODU =>
P55040.01 G1
P55046.01 C1IDU
P55230.01 A8
P55234.01 C1RRIC
P55295.01 A2
P55298.01 C2
P55285.01 B2if the versions are lower than my example. You should make an upgrade.
Warning: certain versions are not compatible between them
Jayesh Satghare: The dac value is how you are able to adjust your 13Mhz clock on your BOIA card on an Ultra site or a BCFA on a TalkFamily. Inorder to get this set correctly you must use a freq counter. This dac value will be different on everysite so don’t try and set all BTS’s to the same dac value. Once you have your freq counter dialed into exactly 13Mhz make sure you click on set as current and then save current permanently. This value will however drift a little to reallign itself with the frequency on your T-1. If it is drifting dramatiaclly check your bits clock in your BSC.
can any body explain me in RBS 2206 written -48v to -60vdc and 4*32A current.
give me reply as soon as possible.In Nokia Metrosite BTS the DAC value was initially set as 2000 with +- 200 tolerance. Unfortunately, the DAC value keeps drifting down.
Does anybody have an idea why? Maybe the initial value is not right?
