Abstract
SELF-SYNCHRONIZING SERIAL TRANSMISSION
OF SIGNALING BITS IN A DIGITAL SWITCH
Abstract of the Disclosure Signaling bits (ABCD) from a plurality of channels are coded in a predetermined manner, multiplexed into a serial bit stream and transmitted on a data path. A receiver for the data includes a multiple level state machine adapted to decode and synchronize to the received coded signaling bits. Each level of the state machine is associated with a respective type of signaling bit and the levels of the state machine are cascaded output to input. The existence of an output signal from the last stage of the state machine indicates the receiver is synchronized to the serial bit stream and thus that the receiver is properly decoding and identifying the signaling bits.
