Engineering Contradiction Analysis
1Reliability
If hardware for precise synchronization control is installed indiscriminately in telecommunication devices, then precise synchronization capability is improved, but hardware cost and hardware design complexity increase excessively
Solution Approach 1:
The PTP module is designed as a separate, independent component that can be selectively inserted into the circuit board via a socket. This segmentation allows the precise synchronization hardware to be divided from the main circuit board, enabling the board to support both PTP and non-PTP applications without requiring all devices to have integrated PTP hardware, thus reducing overall hardware design complexity while maintaining precise synchronization capability where needed.
Solution Approach 2:
The circuit board is designed with a socket that can accept the PTP module, making the board universal enough to support both PTP and non-PTP applications. The selection unit allows the board to function in different modes (PTP or non-PTP) based on whether the module is inserted, eliminating the need for separate hardware designs for different protocol requirements and reducing hardware design complexity.
2Reliability
If hardware for precise synchronization control is installed indiscriminately in telecommunication devices, then precise synchronization capability is improved, but hardware cost increases excessively
Solution Approach 1:
By segmenting the PTP hardware into a separate removable module, the system allows precise synchronization capability to be added only to devices that require it. Devices that do not need PTP can omit the module entirely, reducing their hardware cost. The segmentation enables cost-effective manufacturing by allowing optional configuration based on application requirements.
Solution Approach 2:
The PTP module is designed as a separate, replaceable component that can be omitted in non-PTP applications. This approach allows the system to use expensive precise synchronization hardware only where necessary, while using simpler, cheaper circuit boards for applications that do not require PTP, thereby reducing overall hardware cost.
3Reliability
If separate circuit board designs are created for PTP and non-PTP applications, then protocol-specific performance is improved, but hardware design time and cost increase
Solution Approach 1:
A single universal circuit board design incorporates a socket that can accept the PTP module. This universal board can support both PTP and non-PTP applications, eliminating the need to design separate circuit boards for each protocol type. The board maintains protocol-specific performance through the selection unit, which routes signals appropriately based on whether the PTP module is present, thereby reducing hardware design time while preserving performance.
Solution Approach 2:
The circuit board design incorporates dynamic adaptability through the selection unit, which can switch between different operational modes (PTP or non-PTP) based on the presence of the PTP module. This dynamic capability allows a single static circuit board design to fulfill multiple protocol-specific requirements, reducing the need for multiple specialized board designs and thereby reducing hardware design time.
4Reliability
If separate circuit board designs are created for PTP and non-PTP applications, then protocol-specific performance is improved, but hardware design cost increases
Solution Approach 1:
The circuit board is designed as a universal platform that can support both PTP and non-PTP applications through the inclusion of a socket for the PTP module. This universal design eliminates the need to create and maintain separate hardware designs for different protocols, reducing hardware design complexity while preserving protocol-specific performance through the selection unit's ability to route signals appropriately based on the operational mode.

AI summary
A network switch can include a precision time protocol (PTP) module and a circuit board. The PTP module can provide a first clock signal and include a predetermined interface. The circuit board can include a socket, an oscillator and a selection unit. The socket can be inserted by the predetermined interface to receive the first clock signal. The oscillator can provide a second clock signal. The selection unit can include a first terminal, a second terminal, an output terminal and a selection terminal. The first terminal can receive the first clock signal when the predetermined interface is inserted into the socket. The second terminal can receive the second clock signal. The output terminal can output one of the first clock signal and the second clock signal. The selection terminal can receive a selection signal to control the output terminal to output the first clock signal or the second clock signal.
