ABSTRACT:
By coincidentally injecting a predetermined level of direct current with the transmission of data on a transmission line, multiple signal transmissions on the line can be detected by the presence of a DC level greater than a predetermined level on the line. Once detected, tactics for avoiding multiple signal collision problems can be implemented.
