I faced a particular problem with RBS 2202.The IDB does not get saved in OMT.Initially the PSU units were not getting highlighted in the cabinet info.
They get highlighted on -48 v and 230v AC with internal battery but not on +24v.The site is not coming up.please guide.7th August 2006 at 23:59 #39030MichaelGuest
I have quite an experience with ericsson RBS series especially 2202 and 2206.Timeslot sync problem can be linked to a malfuntioning of the DXU.
6+6+6 Configuration can be achieved in both RBS 2202 and 2206 using CDU-C+( HYBRID couplers will be required to combine the TX paths.CDU-D is a filter combiner.CDU-G and CDU-F are used in RBS 2206.15th August 2006 at 22:15 #39031celtGuest

Hi Jasmine & others,
BTS(Base transceiver System)is a set of equipment, called RBS in Ericsson, to handle a cell in GSM. RBS consists of transmitters, receivers, CDUs,power supplies and antenna system. Each GSM site may be configured in one, two or three sectors and each sector is provided with one TRU to six TRUs.For GSM, RBS200 series and RBS2000 series were used.At present RBS2206 is extensively used. For WCDMA, a 3G technology, RBS3000 series is introduced by Ericsson.In both series, indoor and outdoor models are available.All are pre assembled and require one hour for testing & commissioning.It can be interfaced to transmission through a T1(1.5Mb/s) or E1(2.048Mb/s).Tx power is +44 dBm with combiner and +47 dBm without combiner(CDU).Rx sensitivity is around -125 dBm.It is provided with AC or +ve grounded DC supplies.21st August 2006 at 13:45 #39036emreGuest
