1. IEEE 1588v2 Function Licenses �?Basics
(1) License name: IEEE 1588v2 function fee
(2) License function: determines whether a subrack supports IEEE 1588v2 and time signal transmission. The sales unit is subrack.
(3) License applicable object: subrack
(4) License applicable object unit: Each subrack needs one corresponding license.
(5) License calculation method:
The number of licenses is deducted by 1 every time IEEE 1588v2 is enabled for a subrack.
(6) License BOM code: ( OSN 9800 is used as an example):
82600638 OptiX OTN Platform-IEEE1588v2 (U2000)
2. IEEE 1588v2 Function Licenses �?Usage
(1) Basic control principles:
After loading and activating IEEE 1588v2 function licenses on the NMS, you can query the corresponding license information on the NMS. Then you can enable or disable IEEE 1588v2 for a specific subrack and the NMS will deduct the license quantity or claim the license accordingly.
NE software enables or disables IEEE 1588v2 for a subrack after receiving a command for enabling or disabling the function from the NMS.
Example: If you purchase 10 IEEE 1588v2 function licenses, you can enable IEEE 1588v2 for 10 subracks at most on the NMS.

IEEE 1588v2
IEEE 1588v2 is a precision clock synchronization protocol for measurement and control systems. It defines the Precision Time Protocol (PTP), which enables accurate clock synchronization between distributed and standalone devices in measurement and control systems. With IEEE 1588v2, time synchronization precision can reach the nanosecond level. Synchronization of clock devices includes frequency synchronization and phase synchronization. The IEEE 1588v2 protocol can be used for both clock synchronization and phase synchronization with the focus on the latter.

Whether IEEE 1588v2 requires a license
Yes, an IEEE 1588v2 function license is required to implement this function.

Conditions for enabling IEEE 1588v2
To use the IEEE 1588v2 function on a BITS V3 device, PNSU or TODU boards must be configured in the master subrack. If the master subrack is fully configured with boards, you need to migrate the clock output service to the extended subrack first. Pay attention to the following configuration requirements: 1. You need to configure the PNSU boards to support output of IEEE 1588v2 clocks, but cannot configure 1:1 or 1+1 protection on the boards. 2. You must configure the PNSU boards in the master subrack. 3. You must configure a fan tray assembly in the master subrack. 4. You must configure a cabinet with a depth of 600 mm, for example, N63E-22. 5. The minimum version requirements for related software are as follows: PNSU/TODU: 102 or later MITU: 180 or later SRCU: 138 or later SYNLOCK centralized maintenance terminal: 3.30 (V300R002C20SPC030) or later Remarks: Clock boards support time source query since the previous versions.

OSN 8800 boards that support IEEE 1588v2
If external phase source access is used, the following boards support IEEE 1588v2: 1PPS+TOD time access: TN16XCH, TN16UXCM, TN52STG, TNK2STG, TN16ATE, TN52STI Service time access: TOG, TN55TQX, TN53TDX, THA, TOA, TOX, THX If internal phase transmission is used, the following boards support IEEE 1588v2: OSC mode: TN11ST2 ESC mode: TOG, TN55TQX, TN53TDX, THA, TOA, TOX, THX, LEM24, LEX4, NPO2, TN54NQ2, TN54NS3, NPO2E, TN53NQ2, TN53ND2, TN53NS2, TN57NQ2, TN57ND2, TN52ND2

Whether the THA board support IEEE 1588v2
When the THA board carries GE services and the encapsulation mode is GFP-T which corresponds to GE(GFP-T) on the NMS, the following modes are supported for clock signal transmission: TC, TC+OC, BC, and OC. Note that the TX8/RX8 and TX16/RX16 optical ports do not support IEEE 1588v2.
