Solid off Standalone 3
The Maintenance/Test detects no packet bus faults.
Solid on Standalone This condition cannot normally occur. The LED is always
either off or blinking in standalone mode.
Flashing (1 Hz) Standalone The Maintenance/Test packet bus port detects a packet
bus fault.
1. It takes 5 to 10 seconds for the yellow LED to respond to a change in the state of the packet bus.
2. Because the yellow LED on the Maintenance/Test circuit pack can also be on steady when the digital and
analog test ports on the circuit pack are in use, exact interpretation of the yellow LED may require that the
technician busy out the analog and digital test ports or examine the error and alarm logs for PKT-BUS
errors and alarms.
3. “Standalone” refers to the TN771D’s capability to operate autonomously as a troubleshooting aid.
