ABSTRACT:
Improved modem terminals spaced along a high-frequency triaxial data line a long length. Each modem employs signal delay and differential detection circuitry to detect signals on the line which may have been degraded in transmission. Conversion circuitry and input-output circuitry interface the data line with terminal devices and other data transmission lines.
