TDM to TDM (Cross-Connect) Flow
Each payload-type machine receives the data of bundle-specific TDM timeslots and maps the data into Ethernet
packets. To store a packet, the payload-type machine needs an SDRAM buffer which it gets by extracting a buffer
pointer from the free buffer pool. It then fills the buffer as it processes the TDM timeslots. When a packet is
completed in a buffer, the machine places the buffer pointer in the cross-connect queue. The RX arbiter polls the
cross-connect queue, extracts the pointer, transfers the buffer data to the appropriate payload-type machine, and
then returns the pointer to the free buffer pool. The payload-type machine then extracts the TDM data and inserts it
into the jitter buffer in the SDRAM. From there, the data is transmitted serially out the TDM port.
