Procedures using HTTP interface for Package C ONTs
Procedure 5-19 To check the status of LEDs
1 From the Web-Management System window, click on the States Management tab, as shown in Figure5-15.
Figure 5-15 Main options in Web-Management system window
The ONT status window opens with the ONT states and their current status, as shown in Figure5-10.
2 Click on the LED tab. The ONT LEDs window appears with the LEDS, their color, current LED state, and persistent LED state shown.

where
LED is the mnemonic for an LED on the ONT. Each LED represents a condition or activity on the ONT, such as the condition of the battery or the activity of a data link; see Table5-7 for an explanation of each LED.
COLOR is the color of the LED. The color of the LED represents the status of a condition or activity on the ONT, such as red for failing battery or green for activity on the data link; see the ONT-specific unit data sheet for the meaning of a color for a specific LED and ONT type.
CURSTATE represents the current LED state, where OFF means the LED is not lit, ON means that the LED is lit and the color is solid.
PERSTATE represents the persistent state of the LED, where OFF means that the LED was not lit, and ON means that the LED was lit and the color was solid.
3 Use the scroll bar in the ONT LEDs window to scroll up and down the list of LEDs.
4 Click on the Refresh button to refresh the contents of the window.
5 STOP. This procedure is complete.
Procedures using CLI interface
The following procedure provides the steps to check the status of the ONT LEDs using the CLI interface.
Procedure 5-20 To check the status of LEDs
1 Choose option 8, More options, from the Main menu. The Secondary menu appears.
2 Choose option 6, Retrieve ONT LED status, from the secondary menu.
The ONT LEDs appear with their color, current LED state, and previous LED state shown. For example:

Not applicable.5.10 Checking ranging state of an ONT
The ranging state indicates the operational mode of the ONT as per ITU 984.3.
Table5-8 describes the possible ranging states for an ONT.
Table 5-8 Ranging states of an ONT
This section shows you how to retrieve the ranging state of an ONT.
Prerequisites
The prerequisites are:
• The user access level of the ONT is read only or read-write.
• The steps to access the interface are completed.
• See Procedure5-1 for HTTP interface using the first Ethernet port.
• See Procedure5-4 for CLI interface using the first Ethernet port.
Ranging state Description
Initial state The ONT is on, but is not connected to the GPON.
Standby state The ONT is waiting for network parameters, such as a preassigned equalization delay, or the number of preamble bytes to use in the upstream direction.
Serial number state The ONT is waiting for a serial number request. When the request is received, the ONT registers.
Ranging state The ONT is waiting for a ranging request. Based on the round-trip delay (RTD) time, the P-OLT calculates the ONT’s equalization delay.
Operation state The ONT is ranged. In the operation state, the upstream frames will be synchronized together between the ONTs on the PON.
Also, the upstream transmissions will arrive separately, each one in its correct location within the frame. In this state, the ONT can be halted by the P-OLT, to implement serial number or ranging processes with other ONTs.
Popup state The ONT enters the popup state from the operation state after detecting an alarm, such as loss of signal (LOS) or loss of frame (LOF). In the pop-up state, the ONT stops transmitting in the upstream direction.
Emergency stop state The ONT is in an emergency stop state, and does not receive and transmit data until the P-OLT enables it.
