Huawei OTN OSN 8800 Transmission DWDM System
Short Description:
| OTN Overhead | |
| Specifies whether to enable MSI overheads automatically. If Huawei OTN NEs access OTUk services from third-party NEs, timeslots need to be manually allocated for MSI overheads. In this situation, set MSI Auto Enable to Disabled. Only when AIS Insertion Enabling of PLM or AIS Insertion Enabling of MSIM is set to ENABLE, an ODU-PLM or ODU-MSIM alarm can trigger the Client 1+1, ODUk SNCP, tributary SNCP protection switchovers. | Configuring MSI to Enable Connections Between Huawei and Third-Party Equipment and Parameters: MSI Overhead. Configuring the AIS Insertion Enabling of PLM and AIS Insertion Enabling of MSIM for Protection Switching andParameters: PM Overhead. |
| Optical Line Protection | |
| The TN12HSC1 board is added and it supports OLP bidirectional switching. | Availability |
| Client 1+1 Protection | |
| The TN15LSC/ THA board starts to support the feature. The TN53TSXL/ TN15LSXL/ TN13LQM/ TN12LDX/ TN11LOA/ TN53TDX board starts to support the switching detection time parameter. The ODU-PLM and ODU-MSIM alarms are added as conditions for triggering client 1+1 protection switching. | Availability Dependency and Limitation Trigger Conditions |
| Intra-Board 1+1 Protection | |
| The TN57NS4/ TN15LSC board is added and it supports intra-board 1+1 protection. The TN52NS3/ TN54NS3/ TN53ND2/ TN15LSXL/ TN13LQM/ TN12LDX/ TN53NS2/ TN11LOA board starts to support the switching detection time parameter. The function of setting trigger conditions is newly supported. | Trigger Conditions Dependencies and Limitations Setting Trigger Conditions |
