Dear All,

Can anyone guide me that commercial supply not available and when site load shifted automatically on genset then it is sure that site will not experience outage. but i face this trouble in Huawei gsm that site load not shifted on batteries.let me know what is wrong with this and what is faulty.

I’m a BSS Engineer in a GSM company. There was congestin on TCH and a high value of SDCDR(SDCCH Drop Rate) on one of our site configured 1/1/1. I then added one TRX on the first sector making the configuration 2/1/1. I noticed the congestion on TCH is resolved but the value of SDCDR remained as high as before.

What could be the cause of that problem? Will the add of an SDCCH channel to the second added TRX solve the issue?

Thanks,

Dear All

i want to know the cards (RRI,FIU,E1/T1) used in BTS in detail and also the difference in between them

Hi Jerrys,
In easy way, if you have TCH congestion, than add TRX. Than you will have much more capacity. If you have SDCCH congestion, than add SDCCH channels (change channel configuration from Comb to NonCom) or add more than one NonComb timeslots. One Comb is 4 SDCCH channels and one NonComb is 8 SDCCH channels. But if you have SDCCH drop than you have probably problem with interference. Check Idle Band. And try to find better BCCH frequency.

Hi,

FXC E1/T1 Card: Transmission Unit when there is no MW solution.It can Provide 4xE1(4x2M). Usually used when we have BTS near the BSC or when we want to use HDSL modem. (E1=Europe Standard for 2M,T1=US and some other countries standard)

FXC RRI Card: Transmission Unit when MW solution is available. It to Flexbus. Each FlexBus can connect to seperate ODU(OutDoorUnit like FlexiHopper or MetroHopper). It can provide totaly 16xE1 and ability to work as a Single or HotStandBy(HSB).

FIU 19: Transmission unit when you want to diMultiplex your signal from MW to E1(PCM). It has diffrent configuration
2IDU+2ODU= High Protection
1IDU+2ODU= HSB Protection
Single = witout Protection

Dear Nishant,

I think there is some probem with the CGI u have given in the Hexa decimal.
U have given CGI : 404F700001E39F.

MCC – 404 -> 404
MNC – F -> 15
LAC – 700001 -> 7340033(in question)
Cell ID – E39F -> 58271.

Range of the LAC & Cell ID in GSM is 0 – 65535.

Regards

Hi all, would u plz tell me abt ERRICSSON bts installation

[Shadiq]

Does anyone know if it is possible to add radios to a nokia ultrasite bts without configuring the HW manager accordingly?

Shadiq – 6 Jun 2007

Which card?

alarm: “difference between BTS ans BSC …” appears if you have a mistake on HW.

So you must use HW configurator.

Thank You! Patrick
