System Loopback
There is a system loopback available in the ATM/HDLC Mapper. The loopback can be performed on a per port
basis. When a port is placed in system loopback, the data coming in from the System Interface is looped back from
the Transmit FIFO to the Receive FIFO, a FIFO empty indication is passed on to the Transmit Cell/Packet
Processor, and all data coming from the Receive Cell/Packet Processor is discarded. The maximum throughput of
a single port is limited to half of the Receive System Interface bandwidth in 32-bit mode. A loss of data may occur if
the Receive System Interface clock (RSCLK) has a frequency that is greater than one and one-half times the
Transmit System Interface clock (TSCLK).
