Abstract

Digital Communications systems introduce undesirable audio delay at various points along the transmission path. The Integrated Digital Enhanced Network (iDEN) is no exception. The iDEN system incorporates an HDLC-encoding scheme for mes- sages exchanged between the Base Radio Controller (BRC) and the Transcoder (XCDR). This publica- tion explains how the XCDR can minimize its inbound audio delay by tracking the number of zero-insertions detected in the message received from the BRC.
