How to monitor Huawei DSLAM backup in U2000?

How to monitor Huawei DALSM MA5616 or MA5600T Backup in U2000?

You can check the backups from this path:

You can also modify the backup policy and select the file type you want for the NE you choose:

For the backup result, you can check them only in U2000. For the backups failure, you can check the alarms if your U2000 version is R16C60 or higher.

Unfortunately, there is no function implemented yet to allow us to receive the failed backups alarms via email.

How to Verify CES Service Configuration?

After configuring a CES service on Huawei SDH equipment OSN 3500, you need to verify whether the service configuration is correct.

Prerequisites

• You are an NM user with Administrators rights or higher.
• CES services must be configured as required. For details, see Configuring CES Services in the Configuration Guide.

Tools, Equipment, and Materials

BER tester or SDH analyzer, the U2000

Test Connection Diagram

Figure 1 shows the connection diagram for testing connectivity of CES service. You can replace the SDH analyzer with a BER tester.

Procedure

1. As shown in Figure 1, connect the CES service interface on NE1 to the BER tester.
2. Perform an inloop for the UNI that receives CES services on NE2 on the U2000.
   1. In the Main Topology of the U2000, right-click the required NE and then choose NE Explorer from the shortcut menu. The NE Explorer window is displayed.
   2. Select the board that provides CES services.
   3. In the Function Tree, select the type of the interface that receives the CES services.
      If an E1 interface receives the CES services, choose Configuration > Packet Configuration > Interface Management > PDH Interface from the Function Tree.
      If an SDH interface receives the CES services, choose Configuration > Packet Configuration > Interface Management > SDH Interface on Huawei PQ1 from the Function Tree.
   4. Click the Advanced Attributes tab and then select the interface to perform a loopback.
   5. Right-click the Loopback Mode field, and then choose Inloop from the shortcut menu.
   6. Click Apply.
3. Perform a 24-hour bit error test.
    NOTE:

   Set the coding to HDB3 and pseudo-random binary sequence (PRBS) to 2 ¹⁵-1 for the signals transmitted by the BER tester.

   Set the BER tester according to the encapsulation method that the CES services adopt and the frame format that the E1 interface adopts. Set the timeslots on the BER tester consistently with the CES service timeslots.

   • If the CES services adopt the SATop method, you need to enable the BER tester to transmit unframed signals, double-frame signals, or CRC-4 multiframe signals.
   • If the CES services adopt the CESoPSN method and the interface adopts the double-frame format, you need to enable the BER tester to transmit double-frame signals.
   • If the CES services adopt the CESoPSN method and the interface adopts the CRC-4 multiframe format, you need to enable the BER tester to transmit CRC-4 multiframe signals.
4. Test the performance of the CES services. That is, check whether bit errors occur in the CES services in the 24-hour period.
5. Check for the alarms associated with the CES services. If there is any, see the Alarms and Performance Events Reference and Troubleshooting to clear the alarms.
6. Repeat 3 to 4 to perform the 24-hour bit error test again.
7. Release the inloop that is set on the interface on NE2. For details, see 2.
8. Reconnect the cable to the CES service interface on NE1.
9. Repeat 1 to 8 to test the CES services on all the other 2 Mbit/s interfaces on NE1 and NE2.
10. Repeat 1 to 9 to test connectivity of the CES services on the other NEs.
