An understanding of basic electronics is necessary to comprehend how some facilities (telecommunications paths) are engineered.
We have to learn how to use our anti-static straps because we know that electricity from our fingers, our bodies, can short- circuit a circuit pack and when we're talking about circuit packs, we're talking about thousands of dollars worth of equipment there -- so you're talking understanding static electricity.
You've got to have certain voltages, five volts from a 24 volt supply to DC. You have to understand that it's what voltage is there required to make it work. If the voltage is not there to work -- to make it work, then you're not going to get anyplace-- You have to consider length of cable in the back plane, also, from cable to cable, from one location to the other within the same piece of equipment, also. Resistance again.
Your circuit packs, your transistors, what makes them work? You go back into your schematics again and you read them, you follow a flow of that schematic drawing. It goes through a certain integrated circuit. It goes through a path. It follows this and if it comes out to be another path, you may have to go to another pack that's causing the problem instead of this one particular one. So you have to know basic electronics. Yes, say I'll follow the current flow or a path. So that's where it comes in handy.
