Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different network element product variations are prepared with different physical Ethernet data transmission ports and different ratios of physical E1/T1 data transmission ports, then the adaptability to various operation environments is improved, but the production expenses increase and production maintenance becomes more difficult
Solution Approach 1:
The patent applies universality by designing a single physical data transmission port that can function as either an Ethernet port or an E1/T1 port through software configuration. The port includes an electric connector with multiple connecting poles and signal paths that can be allocated to different logic data transmission ports depending on the required protocol, eliminating the need for multiple specialized port types while maintaining adaptability to various operation environments
Solution Approach 2:
The patent implements dynamics through the use of a changeover switch that can dynamically reconfigure the signal paths between the electric connector and interface units based on the detected data transmission protocol. This allows the physical port to adapt its functionality in real-time according to the connected device type, whether Ethernet or E1/T1, without requiring physical reconfiguration or multiple fixed port types
2Adaptability or versatility
If a network element is provided with as many physical E1/T1 data transmission ports and physical Ethernet data transmission ports as are needed in different operation environments, then the adaptability to various operation environments is improved, but the manufacturing expenses increase and physical space requirements increase
Solution Approach 1:
The patent applies universality by designing a single physical data transmission port that can function as either an Ethernet port or an E1/T1 port through software configuration. The port includes an electric connector with multiple connecting poles and signal paths that can be allocated to different logic data transmission ports depending on the required protocol, eliminating the need for multiple specialized port types while maintaining adaptability to various operation environments
Solution Approach 2:
The patent merges the functionality of separate Ethernet and E1/T1 ports into a single physical port structure. By combining the electric connector, signal paths, and interface units into a shared resource that can be dynamically allocated, the patent reduces the total number of physical ports needed on the network element's outer surface while maintaining the capability to support both protocol types simultaneously across multiple ports
3Adaptability or versatility
If a network element is provided with as many physical E1/T1 data transmission ports and physical Ethernet data transmission ports as are needed in different operation environments, then the adaptability to various operation environments is improved, but the manufacturing expenses increase
Solution Approach 1:
The patent applies universality by designing a single physical data transmission port that can function as either an Ethernet port or an E1/T1 port through software configuration. The port includes an electric connector with multiple connecting poles and signal paths that can be allocated to different logic data transmission ports depending on the required protocol, eliminating the need for multiple specialized port types while maintaining adaptability to various operation environments
Solution Approach 2:
The patent changes the operational parameters of the physical port through software configuration rather than physical reconfiguration. By detecting the data transmission protocol type and dynamically adjusting the signal path allocation and interface unit configuration, the patent allows a single port design to operate under different protocol parameters, reducing manufacturing complexity and expenses while maintaining adaptability

AI summary
The invention relates to a physical data transmission port in a network element of a data network, suited for realizing for instance both an electric packet switched Ethernet connection and an electric time slot switched E1/T1 connection. In the present invention, it has surprisingly been found out that the electric connector (101) and connected circuits provided in the network element can be arranged to support more than one wiring standard. For example the generally used RJ connector can be arranged to support both the RJ45 wiring standard and the RJ48c wiring standard, in which case, by means of said electric connector (101), there can be realized a physical data transmission port that is suited for realizing both an 10/100 Ethernet connection and an E1/T1 connection.
