To add or drop services between a processing board and a line board, realizing service transmission in an SDH network, you need to create SDH cross-connections from the processing board to the line board.
Context
When you query the services of the current NE, the status of cross-connections becomes inactive if the cross-connections exist on the Web LCT but do not exist on the NE.
NOTICE: - You are advised not to configure inactive cross-connections on an ASON network. Otherwise, these cross-connections are prone to conflict with ASON cross-connections.
- After you query cross-connections on an ASON network, the cross-connections on the U2000 are consistent with those on the NE and the inactive cross-connections on the Web LCT are cleared.
Procedure
- In the NE Explorer, select an NE and choose from the Function Tree.
- Click Query to query SDH services from the NE.
- In the Confirm dialog box, click OK. In the Operation Result dialog box, click Close.
- Click Create and set the required parameters in the Create SDH/PDH Service dialog box that is displayed.

NOTE: - If you activate the service immediately, the service configuration data is applied to NEs.
- If you do not activate the service, the service configuration data is only saved on the Web LCT.
- Click OK, the SDH service is created.
