Bildschirmtext (BTX)
BTX (Bildschirmtext, translated as Screentext) has been a german service, allowing to transfer data via telephone line. In the 8bit era, the Deutsche Bundespost (german postal service) still owned the monopoly for telecommunications in germany, so the only (legal) way to transmit electronic data via telephone line has been to use their BTX service.

Note: Schneider also made a BTX module for Schneider Television Sets, although that device had nothing to do with the CPC, its housing was later re-used for the CPC's Schneider RS232 Interface.
