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 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.

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

PROTECTION SWITCHING

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

OW COMMUNICATION

CALL

Buzz

Following Order-Wire communications are possible:

Communication between Local IDU and Local ODU

Communication between Local IDU and Remote IDU

Communication between Local ODU and Remote IDU

Communication between Local ODU and Remote ODU

When back-to-back connection for order wire is provided,

OW communication between different hops are possible.

Back-to-back

When the “Call” button on the IDU is pressed the buzzer sounds on the remote IDU and all the other IDUs

connected through back-to back connections.

OW/RX LEV MONITOR

•Meter – Indicates the Receive

•OW Indicator – Lights when the

OW-ON/OFF switch is set to ON

Under this condition if the indicator is not lit replace the battery.

•OW ON/OFF SW – when set to ON

enables OW communication

between the IDU and the ODU.

•VOL control – Adjust the level of

the OW RX signal.

•Head set Jack – connects the

headset for OW communication

•RX LEV/OW IN connector –

connect the OW/RX Lev monitor to the ODU using the provided coaxial cable

•Battery – use 6F22(UB) / 9V battery

INTERFACES

NEC PASOLINK SYSTEM HAS THE FOLLOWING ITU-T STANDARD INTERFACES

DIGITAL SIGNAL INTERFACES

• Signal Rate Fix Rate : 4x2 Mbps and 2x10/100BaseT(X)

Rate Free : 2/4/8/16 x 2 Mbit/s and 2x10/100BaseT(X)

• Impedance 75 Ohms / 120 Ohms (selectable)

2x10/100Base-T(X) : RJ45

• 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.
