Abstract
Alternate speech and data communication over a single circuit is implemented within a communication network which include first nodes which include both a data source and a speech source. Digital information, comprising either speech parameters or data, is sent in discrete blocks between the first node and a second node connected to the network. An inband signaling bit pattern is included within selected blocks sent by a TX-alternator in the sending node to indicate whether all following digital information is to be interpreted by the receiving node as speech or data and a RX-alternator in the receiving node interprets the digital information in accordance with the last received inband signaling pattern. One exemplary implementation is in a GSM cellular radio network in tandem free operation.
