hi guys, i m just starting my Voip and there is a confusion so plz help me out, a guy told me that the lines that come to our home to which my analog phones attach are infact individual channels of E-1 line that is multiplexed at some point from the CO switch. another guy rejected this concept and said that these are old pots lines. i want to ask that
1) who is right ???
2) if its a pots line than is it simply called a pots line or got some other technical name ??
plz tell me thanks in advance
most likely, the lines you have at home, are never part of an E1. These go straight (more or less) to a room in the C.O. called "permutation", where they can make any type of contact an pairing. From there it goes to the line card of the CO switch that can host like 100 or 200 lines per card, and spans multiple shelf. So no E1.
But at the same time, when you must carry the lines across a long distance, or when you are giving service to larger business or communities, then the multiplexing and conversion ti digital occurs, and you have E1, T1, and other type of circuits.
For the name, I would not use pots when talking to non technical people. Regular telephone line is probably the most widely used name.
