Abstract

Method and apparatus for transporting tone signalling information through a TFO link, proving for detection (6a), in a data stream to the local entrance to the TFO link, of a tone signal to be transported, coding of the detected tone signal into bits of a TFO frame for sending through the TFO link, including setting bits to mark the TFO frame as a containing tone signalling information and setting bits to identify the detected tone signal, whereby the tone signalling information is transported in-band through the TFO link as a marked TFO frame, detection, at the remote exit from the TFO link, of the marked TFO frame and regeneration (7b) of the tone signal, in dependence upon the bits of the marked frame. <IMAGE>
