hi, the lettering orientation on wall jacks is that some industry standard or some type of building code. I’ve noticed that you might see something at a wall jack that will say b-22, c-4, d-122, etc. On the patch panel it will say the same thing. that helps you trace where the wires go from the jack. I’ve seen this sort of thing a lot, but I don’t understand what it is or how it’s done. Are these letters/numbers something that already comes on the patch panel and therefore they make labels for the wall jacks. I don’t really understand this because I’ve never seen the jacks, and everything installed from the ground up. Everywhere I’ve been the existing setup has been put together already. I can’t figure out how they are coming up with these particular numbering/letter things on these jacks. Where is this coming from? what’s the significance or meaning behind this stuff?
