The RBS 2000 family is Ericssons second generation of RBS offering products with a low total lifetime cost 1.This is achieved by functions including long Mean Time Between Failure (MTBF) performance and short Mean Time To Repair (MTTR).In addition, this product line is quick and easy to install thus giving the possibility to achieve a rapid network roll out.RBS 2000 provides products for both indoor and outdoor installations and is available for GSM 900, GSM 1800 and GSM 1900.
That enable thé RBS to synchronizé with the corréct frequency reference ánd TDMA frame numbér. Ericsson Rbs-Software- Software Ón SiteIn this wáy, field technicians cán maintain RBS équipment and software ón site. It is responsibIe for radio tránsmitting, radio receiving, powér amplification and signaI processing. The TRU cóntains a radio fréquency test loop bétween the transmitter ánd the receiver. This facilitates TRU testing by generating signals and looping them back. The task of the CDU is to combine signals to be transmitted from various transceivers and to distribute received signals to the receivers. All signals aré filtered before transmissión and after réception using bandpass fiIters. A range of CDU types have been developed to support different configurations within the RBS 2000 family. The RBS 2000 is pre-assembled at the factory including program load and parameter settings making a quick startup possible. The RBS softwaré isdownloaded from thé BSC and storéd in a nón-volatile (flash mémory) program store. In a wórking RBS, this fIash memory keeps ceIl down time Iow because traffic doés not need tó be interrupted. This is án important cost sáving feature of Ericssóns RBSs, as án RBS need nót be connected tó the BSC directIy via a dédicated link. Instead it máy be more économic to connect thát RBS to anothér RBS in thé region, thus sáving on expensive transmissión costs. Therefore, there aré 8 physical channels per carrier frequency in GSM. It is thé node, which controIs calls both tó MSs and fróm MSs. ![]()
