Lightning and Ground Loop Damage to Multiplexers

Overview RS-232 line drivers and receivers are made for voltages ranging from +15 volts to -15 volts. Voltages exceeding the 23 volt device limit can be induced and damage the RS-232 drivers and receivers. Excessive voltages can be caused by power surges, power dropouts, ground loop currents and lightning. Lightning does not have to strike a building directly to cause damage to data comm equipment. The expanding magnetic field from a nearby lightning strike or even a cloud-to-cloud discharge can easily induce voltage in data lines.

IT must be called to account over emissions

Because of a lack of awareness of the damage IT may be causing, it is often overlooked in companies' green strategies. Some 14 per cent have hit a power limit and are unable to get more electricity into the building.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change.
