The relations between PCU and BSC types as well as the connectivity limits of BTSs, TRXs, TSLs, Abis and Gb TSLs are shown in the Table below:The limits of S11.5's upgrade is come from the still using the old PCU instead of the BSS. Maybe we only have the PCU-s or PCU,right? But who will collect and confirm this information? Need to change some new PCU type? 2I 版本可带 8+1 个 BCSU ，一个 BCSU 可带 2 个 PCU3I 版本可带 6+1 个 BCSU ，
