Huawei OptiX OSN 9800 System Control and Communication Boards TNU2CTU01 Overview

TNU2CTU01: System Control and Communication Board With Clock Processing Function

The CTU board 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.

The CTU board consists of an overhead processing module, clock module, monitoring module, communication module, CPU and control module, and power supply module.

The CTU board has a BIOS DIP switch.

Functions and Features of the TNU2CTU01 Board (System Control and Communication Unit)

Function and Feature	Description
Basic function	Grooms 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. Implements communication between NEs through IP over DCC.
OTN cluster	Back-to-back cluster: When the board works with a TNU3UCXCS board in a U64/U32 Enhanced subrack, the back-to-back cluster is supported. 2+N cluster: not supported
Electrical-layer ASON	Supported
Master-Slave subrack	Supports subrack cascading.
DCC	NEs can be interconnected through the DCC.
Backup mode	Supports 1+1 hot backup. When the active board is faulty, services are automatically switched to the standby board. NOTE: After active/standby switching is completed, NE data must be manually uploaded.

Functions and Features of the TNU2CTU01 Board (Clock Unit)

Function and Feature	Description
Basic function	The board provides system clock signals and frame header signals for each service board.
Physical clock	Supported
IEEE 1588v2	Supported
ITU-T G.8275.1	Supported
ITU-T G.8273.2	When the board is used as the system control board in a back-to-back cluster, ITU-T G.8273.2 is supported. Non-cluster: supported
High-precision clock synchronization	When the board is used as the system control board in a back-to-back cluster, the master subrack of the cluster supports high-precision clocks, but slave subracks do not support high-precision clocks. Non-cluster: supported NOTE: The high-precision clock synchronization function can be implemented only after the corresponding license is obtained.
External clock port	Supported
External time port	Supported
Backup mode	Supports 1+1 hot backup.
