Huawei TNK2SCC System Control and Communication Board with Part Number 03020PSF1 . Description:The SCC board is used for DCC communication, subrack cascading, power supply backup and clock.Table 1 shows the detailed functions and features of the TN11SCC/TN51SCC/TN52SCC/TNK2SCC board.Table 2 shows the detailed functions and features of the TN16SCC.Table 3 shows the detailed functions and features of the TN22SCC/TN23SCC board.Table 1 Functions and features of the TN11SCC/TN51SCC/TN52SCC/TNK2SCC boardFunction and FeatureDescriptionBasic functionAccomplishes the service grooming, configuration management and alarm output of a subrack.Supports the backup of the NE data. When the NE data changes, the real-time database backup function immediately saves the changed configuration data into the storage medium to ensure that no configuration data is lost after the NE is reset (cold) or powered off. This improves the reliability of the NE.Supports the function of the CF card to back up the database. The NE data (except NE IP, NE ID, Gateway ID, and Node ID) and the board software are backed up to the CF card. Backing up data to the CF means that you do not need to reconfigure the NE after replacing the SCC.DCN communicationSupports interconnection and communication between NEs through IP over DCC, OSI over DCC, or HWECC.Active/Standby backupSupports active/standby backup: There are two SCCs in the system that can provide 1+1 hot backup. If the active board fails, the standby board automatically becomes active.Clock functionProvides clock source for the system communications.Subrack cascadingSupports subrack cascading. The SCC accomplishes different functions based on the mode (master or slave) of the subrack in which it is installed. The SCC in a slave subrack processes the overhead bytes, handles alarms and manages the configuration inside the subrack. The SCC in a master subrack performs the same functions as the SCC in the slave subrack, and also processes overhead bytes and handles the alarms of all its slave subracks. The SCC in the master subrack connects to the network management system (NM). The configuration commands are issued to the SCC of a slave subrack through the SCC in the master subrack.Optical-layer ASONSupportedElectrical-layer ASONSupportedTable 2 Functions and features of the TN16SCC boardFunction and FeatureDescriptionBasic functionAccomplishes the service grooming, configuration management and alarm output of a subrack.Supports the backup of the NE data.

This improves the reliability of the NE.Supports the function of the CF card to back up database. The NE date (except NE IP, NE ID, Gateway ID and Node ID) and the board software are backed up to the CF card, so that the NE needs not to be re-configured after the replacement of the SCC.DCN communicationSupports interconnection and communication between NEs through IP over DCC, OSI over DCC, or HWECCwhen used with the TN16AUX.Active/Standby backupSupports active/standby backup: There are two SCCs in the system that can provide 1+1 hot backup. If the active board fails, the standby board automatically becomes active.Clock functionBasic function:Locks the reference clock source.Provides the system with ITU-T clock signals that comply with G.813- and ITU-T G.823 and frame signals.Synchronizes the time of an NE with the time of the upstream system.Clock source selection function:Traces the external clock source, service clock source, or local clock source, to provide the synchronization clock source for itself and the system.Time synchronization function:Synchronizes the time of an NE with the time of the upstream NE.Subrack cascadingSupports subrack cascading.The SCC accomplishes different functions based on the mode (master or slave) of the subrack in which it is installed.
