Abstract:
A method of alternately sending voice and data within a digital telecommunications system which includes a first node containing both a data source and a speech encoder connected to a network and which selectively sends a signal containing either data or speech parameters to said network, said method comprising:providing a second node containing a data receiver and a speech decoder connected to said network for both data and voice communication with said first node through said network;selectively bypassing a speech encoder and decoder within said network to allow discrete blocks of digital information, in the size and data rate of standard speech parameters, to pass transparently through said network from said first node to said second node;sending a first inband signaling bit pattern within one of said discrete blocks of digital information from said first node to said second node indicating that the digital information contained within the remainder of that block and successive blocks of digital information represent speech parameters;sending a second inband signaling bit pattern within a successive one of said discrete blocks of digital information sent from said first node to said second node indicating that the digital information contained within the remainder of that block and successive blocks of digital information represent data;interpreting the digital information received at said second node in accordance with the last received of said first or said second inband signaling bit pattern to enable the alternate sending of both speech and data from said first node to said second node over a single communication channel.
