5.10 Checking ranging state of an ONT
The ranging state indicates the operational mode of the ONT as per ITU 984.3.

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.

5 — ONT management using an ONT interface
Description
The ONT is on, but is not connected to the GPON.
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.
The ONT is waiting for a serial number request. When the request
is received, the ONT registers.
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.
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.
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.
The ONT is in an emergency stop state, and does not receive and
transmit data until the P-OLT enables it.
