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 AUTONo.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 SWControl signal to switch to the

standby CH provided it is in

normal operating condition.

PROTECTION SWITCHINGPROTECTION SWITCHING

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

Wayside 1x2 Mbit/s (option in 16x2 Mbit/s ) (75 or 120 ohms selectable)

In the case of Nx2 Mbit/s systems, each I/O port is independent ,therefore the 2

Mbit/s signal can be used for different applications- such as relaying 2Mbit/s trunk

line or video conferencing.

BER ALARM THRESHOLD

When excessive BER is detected, the IDU insert

AIS into the data streams sent to the MUX

equipment. Threshold value for AIS insertion can

be selected as 1 x 10-3, 1 x 10-4, 1 x 10-5 or 1 x10-6 .

FRAME IDThis item defines the Frame ID of the transmit/receive signal.

The Frame ID is used at the receive station to identify the

correct receive signal.

As a signal with a different Frame ID cannot be received, the

Frame ID of the opposite station should be set to the same ID

number.

In the (1+1) Hot standby system, both No.1 and No.2channels should have the same Frame ID. The number of
