The APOI (Active Point of Interface) has a patented Smart ALC control loop that enables auto calibration per each APOI port. The Smart ALC algorithm will cause the APOI to provide constant pilot signals in all traffic scenarios while maintaining the output power levels required. The APOI also enables manual calibration per port when required by the operators. Up to 5 APOI shelves can be cascaded together via the IP switch and display card. The LCD will display the APOI shelf number.

Remote management can be done via wireless modem or Ethernet. The modem types available are GSM, WCDMA or CDMA 1x. The system can be monitored and controlled via the Axell Wireless’ network management software – AEM.
