TMF3AUX overview

The TMF3AUX board is a system auxiliary communication board.

TMF3AUX01 board implements clock and time synchronization for the entire NE, and can provide system clock signals and frame header signals for each service board.

The TMF3AUX has no hardware DIP switch.

The subrack ID can be configured on the NMS.
The board supports the RST button to clear all the data in the flash memory except the board manufacturing information. The data includes the system data, system parameter areas, and extended BIOS files. The upper layer part of BIOS is not started. The procedure is as follows:
- Press and hold the RST button for 5 to 10 seconds. Release the button after 55 is displayed on the LED.
- Press and hold down the RST button for 30 to 35 seconds within 30 seconds. Release the button after 0F is displayed on the LED.
- Wait until the STAT and PROG indicators on the board are steady green and red, respectively. Then, remove or insert the board.

Functions and Features of the TMF3AUX Board (System Control and Communication Unit)

Item	TMF3AUX
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.
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.

Functions and Features of the TMF3AUX Board (Clock Unit)

Item	TMF3AUX
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. Supports G.8271. NOTE: Only the F3AUX01 board supports clock unit.
Physical clock	Supported NOTE: Only the F3AUX01 board supports clock unit.
IEEE 1588v2	Supported NOTE: Only the F3AUX01 board supports clock unit.
ITU-T G.8275.1	Supported NOTE: Only the F3AUX01 board supports clock unit.
ITU-T G.8273.2	Supported NOTE: Only the F3AUX01 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 F3AUX01 board supports the high-precision clock synchronization function.
Backup mode	Supports 1+1 hot backup.
