Why is a T1 used for voice communications?

T1 FAQ - Frequently asked Questions about T1 Voice and Data ...
Answer - The main advantage of T-1 is cost savings over equivalent service on regular analog lines. In general the cost of most 24 channel T1s is about the same as 12 standard telephone lines. This enables a business requiring 24 phone lines to do so for the cost of 12. Another advantage is that T-1 is a digital transmission and therefore less prone than regular phone lines to loss and interference.

Voice T1s can be terminated in a number of fashions but additional equipment is almost always required. If a PBX (Private Branch Exchange) phone system is being used, a T1 line card can be purchased to integrate it into the phone system. If a system is not being used, a T1 channel bank will split out the 24 channels so that they can be used like traditional phone lines. Voice T1 lines are normally delivered via a jack provided by the local phone company; this jack is normally a RJ-45.
