Hi.
I had a similar situation on the Cisco ONS 15454 MSTP.
I hope you did save the database from NE.
You can try connect to ONS Control Cards vi console RS-232 port and see any message about error.
The RS-232 port is used to connect to the Transaction Language 1 (TL1) management interface. In TL1
mode, the RS-232 port runs at 9.6 Kbps without any flow control. Unlikely to help.
Or install this control card (TCC2,TCC2P, TCC3..) from your node into another node how standby card. Active card do procedure format standby card.You get working standby control card. Then do similar procedure for 2-nd card and
Restore the Database for both card (if you want).
