4. LOOP-UP STATE

In the loop-up state, the active FT1 loopback will provide a continuous loop for the FT1 bandwidth. The data flow is continuously monitored for the loop deactivation commands to deactivate the loopbacks. Also, a loopback timeout is checked. If the loopback timeout is enabled, any loopback that is in the loop-up state in excess of the loopback timeout will be deactivated.
