The CRIT, MAJ, MIN, and REM alarm LEDs on the TCC-I faceplate indicate

whether a critical, major, minor, or remote alarm is present on the ONS 15454

SDH or on a remote node in the network.

In-Service Software Upgrade

The node name, configuration database, IP address, and system software (CTC)

are stored in the TCC-I card non-volatile memory, which allows quick recovery if

power or card failures occur. You can upgrade system software without affecting

traffic on the ONS 15454 SDH if dual TCC-I cards are used. The upgrade takes

place first on the standby TCC-I card. The system verifies that the upgrade is

successful and switches from the active TCC-I card running the older release to

the upgraded standby TCC-I card running the newer release. After the switch, the

second TCC-I card undergoes the upgrade. The TCC-I then loads new software to

each of the installed line (traffic) cards.

Database Revert

The increased memory of the TCC-I allows it to store and revert to the previous

conﬁguration database. After a software upgrade, the TCC-I copies the current

working database and saves it in a reserved location in the TCC-I Flash memory. If

you later need to revert to the original working software load, the saved database will

activateautomatically when you initiate the revertprocess. There isno need to restore

the database manually.
