If the service signal detection function is required after IPA pairs are created, configure detect auxiliary boards.
Context
When you configure the auxiliary detection boards for IPA protection groups, observe the following rules:
- To fulfill the IPA function and judge the fiber break more correctly, detection board and auxiliary detection board must be configured at the same time. IPA must be configured at every site section by section. When there is a fiber break, only the amplifiers located before and after the fiber break point are shut down.
- The detect auxiliary board can be the NS2, ND2, NQ2, NS3, 52TOG, OSC or the OTU.
- An IPA protection group can be configured with a maximum of four detect boards and the different optical interfaces on the same board (such as the SC2) cannot be used at the same time.
- To ensure the reliability of the detection, avoid using only one detect auxiliary board.
- When several detect auxiliary boards are configured, a fiber cut is determined only when all detect boards and detect auxiliary boards detect abnormal signals (such as LOS-MUT, LOS, LOF, LOC or RAI alarms). When any one of the detect auxiliary boards or detect boards detects that the signals are normal, the system determines a normal fiber state.
- An IPA pair can be modified and delete only when the IPA pair is in the ended state.
Procedure
- In the NE Explorer, click an NE and choose from the Function Tree.
- Click Query to query the created IPA information.
- Select the created IPA group from the IPA protection list and click Configure Detect Auxiliary Board. The Configure Detect Auxiliary Board dialogue box is displayed.
- From the Available Ports pane, select proper boards. Click
to add them to the Selected Ports pane.
- Click OK.
- A prompt appears telling you that the operation was successful. Click Close.
- Start the NE Explorer of the opposite NE. Refer to Steps 1 through 6 to configure detect auxiliary boards on the opposite NE.
