This paper discusses the accessibility performances of the second carrier implementation in the 3G system. Thestudy of the second carrier implementation effect is carried out in the area of Palembang. The second carrier isthe carrier added together with the main carrier to the 3G system, which will bring the 5MHz informationbandwidth with the carrier spacing of 25 MHz between the first and second carrier. On the accessibilityperformance will be analyzed the effect of the implementation of the

... cond carrier can be seen from the RRC CSR(RRC Connection Success Rate), CCSR Voice (Voice Call Completion Success Rate), CSSR PS (Call SetupSuccess Ratio Data) and CCSR HSDPA (Call Completion Success Rate HSDPA). Implementation of thisimplementation is divided into two batches of batch 1 and batch 2, wherein the first batch consists of 66 site andthe second batch consists of 33 sites. The results of these analyzes showed that after the implementation of thesecond carrier obtained value of the performance of accessibility is much better than before the implementation ofthe second carrier are exercised and the value of each of the RRC CSR, CCSR Voice, CSSR PS and CCSRHSDPA has met the target KPI (Key Performance Indicator) that have been determined.
