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”).
