Protection switching is provided in (1+1) Twin Path and Hot Standby systems. The receive side protection switching is performed by a Hitless Switch in the 150 M INTFC / OPT INTFC or 10/100BASE-T INTFC module.

Priority 1: Manual switching Control

TX switching

Manual switching is initiated from external equipment (LCT/PNMT)Priority 2: Automatic switching control

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

This apply to both HS and Twin Path configurations. When the Online RX CH fails or LOW BER Alarm is detected 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.

TX Switching, either initiated manually or automatically may cause a short interruption of the data.

SWITCHING PRIORITY ( Provisioning)

1.Non-Priority The switching condition used is non priority (non-homing). After switching the channel selected remains selected even if the alarmed channel is normalized

2. Priority No.1 When both channels are normal always selects CH1 as online. When CH1 is faulty automatically change to CH2 provided it is normal. When CH1 recovers return to CH1 automatically.

AUTOMATIC LASER SHUTDOWN

AUTOMATIC LASER SHUT DOWN FUNCTION

When the optical signal input to the main interface is lost, the ALS function automatically shuts the main interface output laser

ALS DELAY TIME

The ALS delay time can be set to 60 or 180 or 300 sec.

Automatic Transmit power control (ATPC)

ATPC setting parameters:-

1- TX max. = Nominal – (0 ~ 20dB)

2- TX min. = Nominal – (0 ~ 20dB)

3- ATPC RX threshold (Reference ) = -30 ~-70dB

- 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
