Management

The EMS copies any configuration on the Primary PON to the Secondary PON ONTs automatically so they do not need to be managed separately. All changes must be made on the Primary PON ONTs.

Another thing to note is that the Secondary PON should have a signal level 5 dB lower than the primary. This is often accomplished using an SC style single mode fiber optic attenuator inserted into the optical path prior to the splitter. This ensures that the Primary PON always wins at startup and is selected as the Primary PON.

After all the ONTs have been added to the PON, the PON needs to be forced to switch by pulling out the primary fiber. This allows the Secondary PON to learn all the ONTs and minimizes switch time. This should be done each time ONTs are added onto the PON. It should also be noted that the OLT suppresses alarms on the Standby PON such that generally speaking all alarms only occur on the Active PON.

Panorama PON supports redundant network uplinks and network equipment protection via redundant ESU cards. PON protection allows providers to add protection to one or more ONTs, the PON equipment, and the fiber network connecting the PON ports to the ONTs via a Type B/Layer 1 enhancement. Refer to the Application Note, OLAN-PON-Protection, ENG-010459 that provides an explanation of PON Protection and its attributes.

4. In the Parameter section, select the field adjacent to Protection Type and view Type B Splitter (default).
5. In the Primary section, designate the primary PON by selecting PON A or PON B.
6. In the Primary section, under PON A, click the down-arrow adjacent to OLT TID, and select the PON A end of the protection group. The ports on the PON A end that have ONTs configured display under the PON A heading.
7. In the Secondary section, under PON B, click the down-arrow adjacent to PON AID, and select the PON B end of the protection group. The ports on the PON B end that have ONTs configured display under the PON B heading.
8. Once the information has been entered, click the Apply button.

   Note: The operation of creating a protection group takes a few minutes.

9. After creation of the protection group is complete, click the Close button.

Verify Protection Group Status

To check the Protection Group status, do the following:

In the Create Protection Group dialog, click the Status tab.

1. On the Status tab, the Protection Group State (PON A active) and the Operational State (Up/Dn) are displayed. This screen is view only.
   
   
2. Use the Up/Down arrows to sort the ONTs in PON A and PON B in ascending or descending order.
3. Click the OK button to close the dialog.

View Show ONTs

To view the protected ONTs in the Protection Group Management screen, do the following:

1. In the Protection Group Management screen, select a row representing the protected PON for Primary and Secondary.
   
   
2. Right-click on the row to display the drop-down list and select Show ONTs. The ONTs under PON A and PON B are listed.
   
   
3. Use the Up/Down arrows to sort the ONTs in PON A and PON B in ascending or descending order.
4. Click the OK button to close the dialog.

Modify Protection Group

The Edit Protection Group gives the user the ability to edit a specific ONT, or selected ONTs from a protection group.

Use the following procedure to modify a PON Protection Group:

1. In the Protection Group Management configuration screen, select the Edit icon () directly from the Tool Bar. The Edit Protection Group dialog displays.
2. In the Edit Protection Group dialog, click and hover over the ONT to display properties of the selected ONT.
   
   
3. To add ONTs from the primary side of the protection group, right-click the PON A or PON B displayed in both the Primary and Secondary sides, and click Add All.
   
   
4. To erase ONTs from the Secondary side, right-click on PON B and select Erase All to remove all ONTs.
5. When the desired ONT(s) have been modified, click the Apply.button.

Delete Protection Group

Use the following procedure to delete a PON Protection Group:

1. In the Protection Group Management configuration screen, select the protection group that will be deleted. Right-click the selected group and select Delete from the drop-down menu, or click the Trash can icon () on the heading Tool Bar.
   
   
2. When the Warning displays, click the Yes button. The selected group is deleted from the Protection Group Management display.
