ABSTRACT:
An adaptive hybrid arrangement for interfacing a bidirectional communications channel with two unidirectional channels, especially for connecting a two-wire telephone line to a four-wire telephone trunk or repeater, comprises a hybrid having four ports. One port is for the two-wire or bidirectional channel, the second and third are for the unidirectional channels. A multi-element balancing network is connected to the fourth port, i.e. opposite to the port connected to the bidirectional channel. Correlation detection means detects correlation between a signal in one of the unidirectional channels and an error signal in the other. If correlation exists, adjusting means adjusts the balancing network so as to reduce such correlation.
