Abstract

Procedure for the remote verification of telecommunication repeaters located in unattended repeater stations of a bilateral transmission system composed of an attended station and one or more unattended stations, or without personnel, located between said station and a remote geographical point ; with a transmission line to conduct signal waves in both directions, through the system by two different frequency bands, a repeater in each of the unattended repeater stations to repeat in one direction the signal waves of one of said bands of transmission and another repeater in each of the unattended stations to repeat in the opposite direction the signal waves of the other transmission band; whose method is characterized by transmitting from the station served, by said transmission line, several pairs of waves, first and second, of verification, of different frequencies included in the first used transmission and whose differential frequency is included in the second band of transmission; selecting in each of the unattended repeater stations a predetermined pair of said first and second verification waves; translating, in each of the unattended posts, this preset pair of said first and second verification waves, to a third wave of frequency equivalent to the difference between the two verification waves mentioned; return this third wave to the station attended and use it in it to identify the respective unattended repeater station and its transmission status.
