Abstract: A frame code word (FCW) is inserted in a time division multiplexed slot in a modem data stream preferably using an embedded secondary channel. A receiving modem demultiplexes the FCW and compares it against the known transmitted FCW. Based upon the number of incorrect FCW's received, a reinitialization command is generated causing the modems to begin a retraining sequence-in view of the detected error condition.
