Since I am new in this field, I am trying to find ways I Could learn more about communications.
What is the difference between T1, T2, and T3.
I met a friend who who has a T3 line. He is looking for a small system that will do the following
1) Does he really need a T3?
2) Will handle 4 incoming lines,
3) To handle 8 phones (extensions, ststions)
4) Voice MAil system to handle 8 mail boxes.
Can someone help me figure out what will be the best system for him?
Thank you for the help.
