ABSTRACT:
A signal repeater for regenerating digitally encoded signals transmitted in bursts over a single pair telephone line to enable simultaneous communication between a telephone central office and any one of up to four subscriber transmitter/receivers. The repeater decouples signals from the line for regeneration thereof and recouples the regenerated signals onto the line. Clock frequency and phase information characteristic of the decoupled signals is derived in order to facilitate accurate regeneration of the signals. The decoupled signals are decoded and then regenerated to replicate the signals originally produced by the telephone central office and subscriber transmitter/receivers respectively. The regenerated signals are then re-encoded and recoupled onto the telephone line.
