Application of Network Application of Network Management Management

We are managing a Network of Indian We are managing a Network of Indian Railways ( Microwave Repeater Railways ( Microwave Repeater Station ) which is a main source of Station ) which is a main source of Communication media for Indian Communication media for Indian Railways.Railways.

What We have a Number of Divisions What We have a Number of Divisions in the Regional Railways e.g.. Western in the Regional Railways e.g.. Western Railways, and these Divisions are Railways, and these Divisions are having divisional HQ. having divisional HQ.

These divisional Head These divisional Head Quarters are looking after the Quarters are looking after the

administration of Railways administration of Railways Traffic in the division. All Traffic in the division. All

divisions are almost having divisions are almost having Railway Track of almost 200 Railway Track of almost 200

to 250 kms. Consisting 5 to 7 to 250 kms. Consisting 5 to 7 Repeaters of Microwave Repeaters of Microwave Network in the division.Network in the division.The mainpurpose of These The mainpurpose of These

repeater is to boost the signal and repeater is to boost the signal and continue the communication link continue the communication link

for smooth working in the division.for smooth working in the division.

Every Repeater Station is isolated by almost 55 Every Repeater Station is isolated by almost 55 to 60 kms. Distance ,this depends upon the to 60 kms. Distance ,this depends upon the terrain of the region.terrain of the region.

There are many equipment housed at these There are many equipment housed at these stations in order to make communication stations in order to make communication workable, like Transmitters (2 nos.) , workable, like Transmitters (2 nos.) , Receivers( 02), +24 V Power Supply , stand by Receivers( 02), +24 V Power Supply , stand by supply (secondary) using Battery Bank, Stand supply (secondary) using Battery Bank, Stand by Battery Bank, D/ Generator set, Battery by Battery Bank, D/ Generator set, Battery Charger, Float, SPV Supply , Air conditioner Set Charger, Float, SPV Supply , Air conditioner Set etc.etc.

These Transmitters and Receivers are having many important Analog and Digital These Transmitters and Receivers are having many important Analog and Digital signals. These Signals are presently monitored Manually , i.e.. 24 hrs . Man Power is signals. These Signals are presently monitored Manually , i.e.. 24 hrs . Man Power is provided at all these locations. But efficiency and duty attendance is poor. In order to provided at all these locations. But efficiency and duty attendance is poor. In order to get better efficiency ;we have devised a system called NMS for MW . get better efficiency ;we have devised a system called NMS for MW .

Almost 100 + Analog and 56 + Digital Important Signals are required to be monitored Almost 100 + Analog and 56 + Digital Important Signals are required to be monitored and some to the extent of 16 Digital Out Signals for controlling devices like and some to the extent of 16 Digital Out Signals for controlling devices like

Switching of Transmitter, Switching of Transmitter, Switching of Receivers,Switching of Receivers, Switching of Battery Bank from Load to Charger and Charger to Switching of Battery Bank from Load to Charger and Charger to
