Huawei OptiX OSN 9800 M24 System auxiliary Communication Board TMF2AUX

Basic function

• Performs service grooming and configuration management inside the subrack and reports associated alarms to the NMS.
• The AUX board collects overheads of other boards and sends the overheads to the SCC board. Then, the SCC board processes the overheads and sends the processed overheads to the AUX board. Subsequently, the AUX board sends the processed overheads back to the other boards.
• Supports inter-NE communication through IP over DCC or HWECC.

OTN cluster

Not Supported

Electrical-layer ASON

Not Supported

Master-Slave subrack

Supports subrack cascading.

DCC

Supports interconnection and communication between NEs through IP over DCC, or HWECC.

Backup mode

Supports 1+1 hot backup. When the active board is faulty, services are automatically switched to the standby board.

Basic function

• The board provides system clock signals and frame header signals for each service board.
• Clock synchronization: synchronizes the time of an NE to the upstream system time to complete the clock and time synchronization of the entire NE.
• Clock source selection: The board can trace the external clock source, service clock source, or local clock source to provide the synchronization clock source for the board and the system.

NOTE:

Only the F2AUX01 board supports clock unit.

Physical clock

Supported

NOTE:

Only the F2AUX01 board supports clock unit.

IEEE 1588v2

Supported

NOTE:

Only the F2AUX01 board supports clock unit.

ITU-T G.8275.1

Supported

NOTE:

Only the F2AUX01 board supports clock unit.

ITU-T G.8273.2

Supported

NOTE:

Only the F2AUX01 board supports clock unit.

High-precision clock synchronization

Supported

NOTE:

• The high-precision clock synchronization function can be implemented only after the corresponding license is obtained.
• The board must work with the subrack and system control board that supports high-precision clock to support the high-precision clock synchronization function.For details, see Clock Synchronization Feature Guide.
• Only the F2AUX01 board supports the high-precision clock synchronization function.

Backup mode

Supports 1+1 hot backup.
