ABSTRACT:
A remote level measurement system for use in a multi-terminal communications system wherein a plurality of remote terminals are connected to a master terminal by a distribution network for bi-directional transmission of signals. The remote terminals are adapted to receive and transmit signals on the network. work. The master terminal is adapted to transmit an interrogation signal to a selected remote terminal and wait for a period of time sufficient for the interrogation signal to be transmitted to, and detected by, a selected remote terminal and a reply signal to be sent back to the master terminal by the remote terminal. At the expiration of that time the master terminal samples and measures the analog level of the reply signal.
