Configuring the Working Mode of the 52TOM Board

Before using the 52TOM board, you need to configure the board working mode and port working mode for the 52TOM board.

Prerequisites

The 52TOM board must be created.

No cross-connection exists on the board when the board-level mode switching occurs on the board.

No logical fiber exists on the optical interface when the board-level mode switching occurs on the board.

Context

You can set the Cascading or Non-Cascading mode for the 11TOM and 52TOM boards.

When the Cascading mode is selected, a maximum of eight channels of Any services of multiple rates (<2.5 Gbit/s) are accessed through the SFP module from the client side of the board. Then, the multiple channels of client-side signals are multiplexed to different timeslots of the one-channel or two-channel ODU0 or the one-channel ODU1.
When the Non-Cascading mode is selected, a maximum of eight channels of Any services of multiple rates (<2.5 Gbit/s) are accessed through the SFP module from the client side of the board. Then, the multiple channels of client-side signals are multiplexed to different timeslots of the one-channel (a maximum of eight channels) ODU0 or the one-channel (a maximum of four channels) ODU1.

NOTE:

In the case of a 52TOM board, you need to set the cascading or non-cascading mode for the board, and the application mode, such as the ODU0 mapping, ODU1 mapping, tributary mode, and tributary-line mode, for each port. In this way, different signal flows can be realized. There are 14 types of working modes for the 52TOM boards.

Procedure

In the NE Explorer, select a 52TOM board, and choose Configuration > Working Mode from the Function Tree.
In the Board Working Mode pane, set Working Mode to Cascading or Non-Cascading.
In the Port Working Mode pane, select the desired optical interface. Double-click the Port Working Mode field and select the corresponding mode from the drop-down list.
Click Apply.
