The New OSN6800 Equipment Is Not Effective

Problem description

1. The network is as follows :A(gateway network element) osn680-b (new start OSN6800 equipment) is linked down and protected by OLP(OTS). There are 5 waves between A and B.

2. B network element cannot find B network element in the upstream A(gateway network element)ECC routing after the completion of single station measurement and optical channel tuning, and the network pipe cannot create B network element.

The process

1. Check the upstream A(gateway network element) receiving B network element direction of the optical amplifier (TN12OBU103) receiving light -11.9 DBM is normal.

2. Check upstream A(gateway network element) of the direction of the receiving B network element of the direction of SC2 light -32.5 DBM normal.

3. The main optical cable used for ODF testing at the site of B network element received light -10.8 DBM is normal.

4. Test the RO port of B network element OLP single board without light output.

5. The on-site ODF test B mesh spare optical cable has no optical reception, and the OLP single board is only equipped with the main and standby optical cable, while the main optical cable has a normal optical reception of -10.8dbm. Suspected B net element OLP single board problem.

6. Connect the main optical cable of B network element to the RI2 and TO2 protection channels of OLP single board to test the normal output of -11.8dbm after OLP single board R0.

7. Network management queries the ECC routing of upstream network A to see network B, and then creates and uploads network B normally.

8 OLP protection configuration of network elements, check B: empty, configuration OLP protection group found that the logic of OLP veneer veneer not to add, add the OLP veneer and then configure protection logic group, master, the optical cable network elements will B back to normal, and then test the OLP veneer output - 11.9 DBM to normal after R0, again, through normal login network monitoring network elements B, problem solving.

returning

1, the logic of OLP added, not single board did not run normally when the default XuanShou standby channel, single B yuan net station test personnel forget to add the logic of OLP veneer, not configured OLP protection group, at the same time result in monitoring the spare cable interrupt.

The solution

1. Solve the problem of configuring protection group after adding OLP logic board to B network element.

Suggestions and summaries

1. The schematic diagram of OLP single board is as follows:

Receiving direction: the optical power detection module detects the detection signal extracted from the main and standby signal and reports the result to the control and communication module. The control and communication module compares the optical power of the two signals, and controls the optical switch action according to the advantages and disadvantages of the optical power, so as to select and receive the main back-up channel optical signal.

Need in OLP veneer logic software after the normal load (i.e. the veneer normally starts running), to test the normal rearrangement of, such as veneer not on electricity or not normal default is XuanShou standby channel starts runtime. This is true of all OLP and DCP veneers so far.

2, new start single station test personnel must pay attention to in the OLP protection scenario, needs to be done in single stand adjustable measuring OLP protection configuration, to prevent after the single stand adjustable measuring device configuration data loss, as a result of power lost in 30 minutes, after completion of the match data manually perform a "backup data to the master control board".
