PROTECTION SWITCHINGProtection switching in Pasolink (1+1 ) system has several switching priorities. Priority 1: Manual switching Control Manual switching is carried out by selecting from the front panel OPR SEL SW [No.1 AUTONo.2] When switched from here both TX and RX sides switches at the same time. Priority 2: Remote switching Control Switching is initiated from external equipment (LCT/PNMT) Priority 3: Automatic switching control When the OPR SEL SW is set to Auto position, for any alarm in the online equipment, traffic will be switched to the standby equipment automatically. TX and RX switchover are performed independently.TX switching In the (1+1)HS system transmit switching is carried out by setting the standby ODU out put to off by Muting it. The data signal is transmitted in parallel to both CH1 and CH2. TX PWR ALM TX LO APC ALM ODU IF INPUT ALM MOD ALM TX DPU ALM CPU ALM RX switching When the Online RX CH fails, the ALM CONT circuit in the SW Board initiate a RX SW Control signal to switch to the standby CH provided it is in normal operating condition.

Maintenance

** Types of Maintenance1- Preventive Maintenance ( periodical ) 2- Corrective Maintenance

** Precautions Before beginning maintenance, notify the opposite station that maintenance is about to begin. After equipment starts-up, allow the equipment to warm up for at least 30 minutes. During maintenance, set the IDU to maintenance mode using a PNMT according to the user manual. After completing the maintenance operation, restore all connections to normal.Pasolink V4 94
