3.Core functional characteristics

Functional Module Technical Description System Value

IEEE 1588v2 supports high-precision time synchronization protocols, providing nanosecond level time synchronization accuracy, and supporting boundary clock (BC) and transparent clock (TC) modes to provide critical support for time sensitive services such as 5G mobile backhaul, meeting 3GPP's stringent requirements for air interface synchronization

The system clock source is equipped with a high stability crystal oscillator, which can serve as the main clock source of the system, providing a reference clock for the entire sub frame to ensure that all business cards work on the same clock reference and guarantee business quality

The BIT interface supports receiving external clock signals (2MHz/2Mbit/2KHz) from BIT devices, seamlessly integrating with existing synchronization networks in accordance with ITU-T G. 703 standards, and can obtain synchronization from external high stability clock sources

Clock quality level monitoring: Real time monitoring of the quality level (QL) of the selected clock source, following the ITU-T G.781 standard to automatically select the optimal clock source in complex synchronous networks, avoiding timing loops

SSM processing supports the extraction, processing, and forwarding of synchronous status messages (SSM) to achieve automatic configuration and fault protection of synchronous networks

Automatic switching of clock source supports selecting system clock from multiple sources such as BITS1, BITS2, 1588v2, internal oscillator, etc., and automatically switches to ensure uninterrupted system clock, improving network survivability

Enhanced hold mode enters hold mode when all external clock sources are lost, using internal high stability crystals and intelligent algorithms to maintain clock accuracy and maintain business clock stability for a long time, which is superior to traditional hold mode

1+1 hot backup supports two STG boards to form a primary backup relationship.In the event of a primary board failure, the backup board can take over the business in milliseconds without interruption, improving system availability

9.Application scenarios

Core Value of Application Scenario Deployment Method

The 5G mobile carrier network is deployed at the aggregation layer and core layer nodes, serving as a 1588v2 boundary clock or transparent clock to provide nanosecond level time synchronization for 5G base stations, meeting the strict requirements of 3GPP for air interface synchronization

Traditional SDH/OTN network synchronization nodes are deployed at sites that require BIT clock synchronization, providing devices with highly stable system clocks compatible with existing network synchronization architectures and ensuring traditional business clock requirements

The core clock source node is connected to a BIT device or GPS/Beidou receiver, serving as the clock source for the entire synchronization network and providing high-precision and highly reliable time and frequency references for the entire network

Multi level clock synchronization network is deployed at all levels of nodes to achieve the step-by-step transmission of clock and time signals, building a reliable clock synchronization network and ensuring business quality

Smart grid/financial dedicated lines are deployed in dedicated line networks that require high-precision time synchronization to meet the strict requirements of time synchronization for wide area measurement and high-frequency transactions in the power grid

10.Maintenance and ordering information

Project Information

Component code TN13STG

Ordering instructions: When placing an order, it is necessary to confirm whether a matching clock cable (such as SMB to BNC) and 1588v2 optical module (if using an optical port) are required

On site operation supports hot plugging, but the synchronization status of the two boards must be ensured during the main and backup switching

After testing and verifying the installation, clock synchronization function testing, 1588v2 time synchronization testing, BITS interface connectivity testing, and primary/backup switching testing are required

Spare parts management suggests configuring spare parts at critical nodes in the network to quickly restore faults

Software dependency requires support from the host software version (V100R006C00 and above)

Core Summary:

TN13STG is an enhanced system timing generator board in the OSN 9800/8800/6800 platform.As an upgraded version of TN12STG, it adds IEEE 1588v2 high-precision time synchronization support (nanosecond precision, BC/TC mode) while maintaining the traditional BIT clock synchronization capability, and is equipped with 1PPS+TOD interface and dedicated 1588v2 interface.This enables it to simultaneously meet the frequency synchronization requirements of traditional SDH/OTN networks and the time synchronization requirements of new services such as 5G bearer, making it a core component in building a unified synchronization network for the future.

Core values and positioning:

Time synchronization ready: Added IEEE 1588v2 support, providing nanosecond level time synchronization for 5G carriers.

Dual mode synchronization capability: Supports both traditional BIT frequency synchronization and 1588v2 time synchronization for smooth evolution.

Enhanced retention performance: The 7-day retention mode has better accuracy than traditional solutions, improving network survivability.

Collaboration with TN12STG: TN12STG is used for pure frequency synchronization scenarios, while TN13STG is used for new networks or upgraded nodes that require time synchronization.

Application suggestion:

This board is the preferred component for synchronous networks in the 5G era on the OSN 9800/8800/6800 platform, especially suitable for scenarios that require simultaneous support for frequency synchronization and time synchronization, such as 5G carrier network aggregation/core layer, smart grid, financial dedicated line, etc. For new networks, it is recommended to directly use TN13STG to obtain complete time and frequency synchronization capabilities; For existing TN12STG networks, they can be gradually upgraded to TN13STG at nodes that require time synchronization.
