ABSTRACT:
A multi-node time division multiplexing (TDM) system is disclosed. The improved method and apparatus utilizes an asynchronous synchronization packet (ASP) to synchronize the timing in all the nodes of the system. In some embodiments, the ASP also maps the time slots in a data frame to particular nodes. The ASP is sent at the start of each data frame to all the nodes in the system and each node synchronizes itself to the time of receipt of the ASP, thus establishing frame-based timing for all the nodes. Additionally, the ASP can contain a table that maps the data frame time slots to the nodes in the system.
