TNU5CTU, System Control and Communication Board With Clock Processing Function
Applied to Huawei to OSN 9800 U32 and U64
TNU2CTU, TNU4CTU, and TNU5CTU boards cannot be used together in the same subrack
Supports Groom services, manages configurations, and reports alarms in a subrack
Backs up NE Data. When the data of an NE changes, the system control and communication unit immediately saves changed data to a storage medium to ensure that the NE data still exists after the NE undergoes a cold reset or power failure. This feature improves NE reliability
Supports communication between NEs through IP over DCC
Supports Electrical-layer ASON, Master-Slave subrack, DCC, Physical clock, IEEE 1588v2, ITU-T G.8275.1, ITU-T G.8273.2 and High-precision clock synchronization.
TNU5CTU is a system control and communication board with the clock processing function. On an NE, the CTU board interoperates with the NMS to manage other boards and implements communication with another NE.
