Pasolink V4 45

Protection switching in Pasolink (1+1 ) system has several switching priorities.

Priority 1: Manual switching Control

Priority 2: Remote switching Control

TX switching

Switching is initiated from external equipment (LCT/PNMT)

When switched from here both TX and RX sides switches at the same time.Manual switching is carried out by selecting from the front panel OPR SEL SW [No.1 –AUTO—No.2]

Priority 3: Automatic switching controlWhen 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.

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.

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.

PROTECTION SWITCHING

When Hitless switch is used make sure that the difference between the two IF cable lengths are less than 50 meters

Automatic Transmit power control (ATPC)

ATPC setting parameters:-

1- TX max. = Nominal – (0 ~ 30dB)

2- TX min. = Nominal – (0 ~ 30dB)

3- ATPC RX threshold (Reference ) = -30 ~-80dB

- ATPC will start with the TX min. power

- When the RX level of the opposite site is decreased to be below the reference RX

- The ATPC Will start increasing the TX power up to TX max. in one dB steps until increasing the RX level of the opposite site to be over the reference level

- The ATPC will maintain the RX level within 5 dB over the reference level

Maintenance

Pasolink V4 94

** 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.
