Abstract
A system and method are provided for transporting FTFL messages in a G.709 network-connected simplex device. The method comprises: receiving messages from a first source in a digital wrapper frame format with overhead bytes in every frame; recovering FTFL information from the received message overhead bytes; and, selectively supplying modified FTFL information for transmit message overhead bytes to the first source. Recovering FTFL information from the received message overhead bytes includes recovering a 256 byte FTFL message, including a 128-byte forward message and a 128-byte backward message. Selectively supplying modified FTFL information for transmit message overhead bytes to the first source includes the substeps of: examining the received messages to determine errors; generating a backward message to report the determined errors; overwriting the received backward message with the generated backward message to create the modified FTFL information; and, in response to overwriting the received backward message with the generated backward message, sending a FTFL_status_out signal. Then, the method further comprises: transmitting messages to the first source with the modified FTFL information in response to the FTFL_status_out signal.
