下图为配置2个RF模块1个小区时的接法，2个RF模块最大可做到12+12+12的配置 天馈系统的连接，下图为配置1个RF模块3个小区时的接法，可做到最大6+6+6的配置 Network on the background, boxes appear by animations EAC connector pin assignments The EAC connector on the RF module is an RJ45 connector with 4 input lines. It is typ- ically used for monitoring local alarms when the RF Module is located far away from the System Module. The EAC connector can also be used for monitoring FPMA or FPDA alarms when these modules are used for supplying power to the remote RFModule. The EAC alarm lines are configured with the 2G Flexi BTS Site Manager during commission- ing. They cannot be configured with the BSC. The cable connected to the EAC connec- tor is not auto-detected. Alarms are monitored by the RF Module and reported to the System Module via the optical cable. Alarm lines must be grounded to test the alarms (if configured as “Closed when active”).
