When you think of Telephone you automatically think cellular phones.
Well here is a brief history of landline phones for my pals who want to wrap their heads around this media of telecommunications.
Very brief, the telegraph sent electric pulses from one place to another. And those lines were later converted to 2 pair lines. It takes one pair for conventional telephone to work. It started with operators pluging in a mono head Phone like jumper into a plug when you wanted to talk to some one. That plug had a tip and a ring. Therefore you had tip and ring connections.
So that orientation used to mater it was simple. that was until you had something that they added that according to my Trainor was called a polarity guard it basically made it to where tip and ring did not matter. Now professionally it matters since you want to look like you know what your doing haha.
Ok now there are different ways to drop Telephone in to your home and business. We call those drop cables and just plain cable pairs for a large business. While homes have 1 to 6 pairs at a house we call those drop cables. Business can have 1 to 100 pair cables. The inside wire would what we call house cable. That can differ too. You can have a bunch of 100 pair cables that are separated in bundles called binder groups. And we will get to that after I finish with the drops and cables.
The homes usually have 2pair these days as needing 6 phones or even more than one is rare due to dsl being able to travel over a single line these days. The drops are identified as tip top, right ridge red. Some drops do not have colors so you look for a ridge you can feel with your finger that is red ring. Those are self supporting drops made of steel and copper, ment for aerial placement. The 2 pairs have 2 colors and the six pair have 6 different colors. In business it can be 100 different colors or more. Underground cables are usually 2 pairs 2 colors maybe 6 for a home and for business well more.
That brings us to color groups.
Blue,orange,green,brown,slate.
Usually if it is modern wires it will be paired with
White,red,black,yellow,,violet
They go in repetitive groups of 5
Like so
Blue/white,orange/white, green/white, brown/white, slate/White
Then the colors move down only the ring side stays the same
Blue/red, orange/red....and so on.
