Creating and Deleting Intra-Board 1+1 Protection

The intra-OTU optical channel protection group is the basis of creating the intra-OTU optical channel protection. To realize the intra-board optical channel protection, each node on the network that is configured with the intra-board optical channel protection should have its intra-OTU protection group created.

Prerequisites

The dual fed and selective receiving OTU must be configured. Or the OLP/DCP board must be configured.

Background Information

The intra-board 1+1 protection is of two types in terms of its implementation way:
  • Protection achieved by the dual fed OTU.
  • Protection achieved with the combination of the DCP or OLP because the OTU board has no dual fed ability.
The dual-fed OTU is 2.5G OTU, that is LQMD. The OTUs that need the combination of the DCP or OLP to achieve the intra-board 1+1 protection are mainly 5G, 10G or 40G OTUs, such as the L4G.

In the case of the intra-board 1+1 protection, you need to create a protection group at both the source and sink NEs to achieve bidirectional protection.

NOTICE:
  • In the case of theOptiX OSN 3800A/6800A intra-board 1+1 protection configured by using the OLP or DCP board, when the channel information detection is configured, the revertive mode can be set to only the non-revertive mode.
  • In the case of the OptiX OSN 1800(NA) intra-board 1+1 protection configured by using the dual fed and selective receiving OTU board, any of the optical interfaces on the WDM side can be used as the working channel. When the protection is deleted, however, the services are forcibly switched to optical interface 1(IN1/OUT1) or 3(IN3/OUT3).
  • In the case of the OptiX OSN 1800(NA), when Channel Use Status of optical interface 2(IN2/OUT2) or 4(IN4/OUT4) is Used, intra-board 1+1 protection can be configured.
  • The attribute settings of client-side services in the main path and those in the standby path must be the same. Otherwise, the services are not available.

Procedure

  1. Click the NE in the NE Explorer, and choose Configuration > Port Protection from the Function tree.
  2. Click New in the Port Protection interface.
  3. Click OK on the Confirm dialog box displayed.
  4. In the Create Protection Group dialog box displayed, select Intra-Board 1+1 Protection from Protection Type.
    • As for the intra-board 1+1 protection that adopts the dual-fed and selectively receiving OTU, select the NE where the OTU resides as the NE with Working Channel, and select the two WDM-side optical ports of the OTU as Working Channel and Protection Channel respectively.

    • As for the intra-board 1+1 protection that achieved with the combination of the DCP or OLP and the OTU board, select the two WDM-side optical ports of the DCP or OLP as Working Channel and Protection Channel respectively.

      NOTE:
      • When you use an OLP to configure intra-board 1+1 protection, in the Working Channel, choose interface 1(IN1/OUT1) of the OLP; in the Protection Channel, choose interface 2(IN2/OUT21) of the OLP. Otherwise, the protection units cannot work normally.
      • When you configure the extended mode of intra-board 1+1 protection realized by an OLP or DCP board working with the OTU boards without the dual fed and selective receiving function, the OTU acts as the monitoring unit, thus NE with Control Channel/Monitoring Channel, Board with Control Channel/Monitoring Channel and Control Channel/Monitoring Channel should be set.
  5. Click OK. The Operation Result dialog box prompts that the operation is successful. Click Close. The created protection group is displayed in the interface.
  6. Start the NE Explorer of the opposite NE. Then, refer to Steps 1 through 5 to create the intra-board 1+1 protection on the opposite NE, to create the reverse protection.
  7. Optional: Select one protection group and select State > OOS at the bottom of the interface.
  8. Optional: Click Delete. Click OK on the Confirm dialog box displayed. The Operation Result dialog box prompts that the operation is successful. Click Close. The protection group can be deleted.
