Abstract: . Exchanges can carry more subscriber lines by using digital signals, rather than analog signals, on existing copper lines. Digital transmission techniques are already well known for their noise immunity, signal , throughput without requiring new lines. The interface between a local exchange and the subscriber is called , subscriber loops use analog line cards. Remote terminals and exchanges use digital line cards to interface , received from each subscriber to a digital signal. These digital signals are combined and sent to other -
