Embodiment 1

[0049] In this example, see figure 1 , a method for updating the status of a PON system, the PON system includes an OLT and a network management terminal, the OLT includes a user-side device and a sub-card system, the sub-card system includes several PON ports, each PON port Corresponding to connecting several ONUs, the state update method includes:

[0050] Step 100 , for each PON port, the daughter card system judges whether the frequency is higher than a first threshold, if yes, execute step 103 , if not, execute step 101 .

[0051] Step 101 , the daughter card system judges whether the frequency is less than a second threshold, if yes, execute step 102 , if not, execute step 100 again.

[0052] Step 102, the sub-card system delays the states of all ONUs corresponding to the PON port for a first time interval, then transmits them to the user-side device, and then executes step 104.

[0053] The above step 102 can ensure that although a small number of ONU states change in...

Embodiment 2

[0065] In this example, see image 3, a method for updating the state of a PON system, the PON system includes an OLT and a network management terminal, the OLT includes a user-side device and a sub-card system, the sub-card system includes several PON ports, a metering A counter and a timer of the state change times of all ONUs corresponding to the PON mouth, each PON mouth is correspondingly connected to some ONUs, and the state update method includes:

[0066] Step 1000, for each PON port, enable the counter and the timer at the same time, the daughter card system judges whether the count of the counter reaches a third threshold, if so, execute step 1001, otherwise, execute step 1002.

[0067] Step 1001 , determine whether the count of the timer is less than a first preset duration, if yes, reset the count of the counter and reset the count of the timer to zero and then perform step 1004 , otherwise end the process.

[0068] Step 1002 , determine whether the counting time ...

Abstract

The invention discloses a PON system and a state updating method thereof. The PON system comprises an OLT. The OLT comprises a piece of user-side equipment and a sub card system. The sub card system comprises a plurality of PON ports of which each is correspondingly connected with a plurality of ONUs. The state updating method comprises the following steps: S1, for each PON port, the sub card system judges whether a frequency is higher than a first threshold, executes the step S2 if the frequency is higher than the first threshold, and executes the step S1 again if the frequency is not higher than the first threshold, wherein the frequency is the frequency of state change of all the ONUs corresponding to the PON port acquired by the sub card system; and S2, the sub card system transmits the states of all the ONUs corresponding to the PON port to the user-side equipment. The internal communication pressure of the OLT of the PON system is small, the performance of the PON system is more stable and reliable, and the user-side equipment can acquire the states of the ONUs more reasonably and accurately.

Description

technical field [0001] The invention relates to a PON system and a state updating method thereof. Background technique [0002] PON (Passive Optical Network: Passive Optical Network), the PON system is mainly composed of the OLT (Optical Line Terminal: Optical Line Terminal) of the central control station, the ODN (Optical Distribution Network: Optical Distribution Network) including passive optical devices, and the user end. ONU (Optical Network Unit: Optical Network Unit) composition. [0003] The status information of the ONU is reported to the sub-card system in the OLT through the MPCP (Multi-Point Control Protocol: Multi-Point Control Protocol) message. After receiving the reported information from the ONU, the OLT sub-card system transmits the status information of the ONU to the OLT. The user-side device (OLT main control panel) The OLT user-side device updates the local display status according to the obtained status information. The disadvantage of this method is...
