SYSTEM SETUP ROI-S05749 For example, at the station A, when the NLite E equipment detects the OC3 input Loss Of Signal (LOS) and/or Loss Of Frame (LOF), the information is transmitted to the station B by using RFCOH. When the station B detects the information, NLite E equipment stops the OC-3 output signal. Similarly, it is the same even if a receiving input level down or loss of radio frame (LOF) appear in station B.
SYSTEM SETUP ROI-S05749 3.5.7 Cross Polarization Interference Canceller (XPIC) Reset Control For the Cross Polarization Interference Canceller (XPIC) to function properly, signals for both Main Master and Sub Master sides must be received normally. For this reason, when either signal is in abnormal condition, the XPIC RESET function provides a way for turning off the XPIC operation. Local/Remote XPIC reset can be controlled separately to the Main Master and Sub Master.
SYSTEM SETUP ROI-S05749 3.5.8 Network Management (Optional) The Network Management System (NMS) configuration is shown in Fig. 3-7.
