摘要: A method of reliably transmitting signalling tones employs a radio communication unit suitable for encoding (303) data packets. The has processor (101) processing first signal, which is incompatible use with tones. further includes an input device (110) providing signals when asserted. In preferred embodiment, the enabled to process and user does not assert (110), transmits processed signal. On other hand, enabled, asserts (304) repeated packets, duration assertion, identify particular tone.
