In this user interface, you can enable or disable the multiframe structure identifier (MSI) overhead feature and set the timeslots occupied by the MSI overheads to be received and sent and other parameters.
MSIs directly reflect the types of services carried by tributary timeslots and the tributary ports occupied by services. Based on MSIs, lower order signals can be decapsulated from higher order signals.
In the NE Explorer, select a board and choose from the navigation tree.
