meaning behind wall jack letters and how they come up with them.
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?
