Abstract
A selective call-waiting system for telephony use samples transmission on a busy line if the line subscribes to the selective call-waiting service, and avoids interrupting the transmission with a call-waiting signal if the transmission is data-type. If the transmission on the busy line subscribing to the selective call-waiting service is voice-type, the system sends a call-waiting signal. Signal analyzers are disclosed, as well as methods for practicing the invention.
