seconds. If the network loop code detection is programmed for automatic loop code, the LIU is configured to
detect a Loop-Up code. If a Loop-Up code is detected for more than 5 seconds, the XRT83L314 will
automatically program the channel into a remote loopback mode. The LIU will remain in remote loopback even
if the Loop-Up code disappears. The channel will continue in remote loop back until a Loop-Down code is
detected for more than 5 seconds (or, if the automatic loop code is disabled) and then automatically return to
normal operation with no loop back. The process of the automatic loop code detection is shown in Figure 15.
