Configurable Network Interface Device for Multi-Service Telecommunication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of a consistent interface between telecommunication service providers' networks and customers' premises wiring leads to logistical issues and limited flexibility in upgrading or modifying networks, as well as customer frustration, due to varying hardware and software configurations required for different services like xDSL, ADSL, and telephone wiring schemes.
Innovation Solution
A network interface device and system that can receive and distribute multiple sets of telecommunication information, including voice, data, and video signals, and is programmable to configure its behavior based on configuration information, allowing for isolation between internal and external transport media, enabling efficient service provision and upgrade without disrupting existing services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If proprietary hardware and custom configurations are used for different telecommunication services, then service functionality is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The network interface device is designed as a universal platform that can provide multiple telecommunication services (xDSL, ADSL, VDSL, telephone, data, video) through software configuration rather than requiring different proprietary hardware for each service type. The device includes multiple interfaces and can be programmed to handle various service requirements, eliminating the need for service-specific hardware configurations.
Solution Approach 2:
The invention uses programmable parameters and software-based configuration to adapt the network interface device for different services. Instead of changing physical hardware parameters for each service, the system modifies operational parameters through software, allowing the same hardware to support multiple services with different configurations.
2Ease of operation
If service personnel must enter customer premises for installation and maintenance, then service configuration can be performed, but logistical issues and customer frustration increase
Solution Approach 1:
The network interface device incorporates self-configuration capabilities through automated discovery protocols and plug-and-play functionality. The device can automatically detect connected equipment, negotiate service parameters, and configure itself without requiring service personnel to physically visit the customer premises, enabling remote service deployment and reduction of service call frequency.
Solution Approach 2:
The system implements feedback mechanisms where the network interface device continuously monitors service status, detects configuration needs, and automatically adjusts settings or requests remote configuration updates. This feedback loop enables the system to maintain optimal configuration without requiring periodic on-site service visits.
3Adaptability or versatility
If discrete programmable interfaces are implemented between provider network and customer premises, then flexibility for upgrades and modifications is improved, but device complexity increases
Solution Approach 1:
The network interface device implements dynamic reconfigurability where service parameters, bandwidth allocation, and operational modes can be changed in real-time through software updates. The device architecture allows dynamic adaptation to new services and technologies without requiring hardware changes, enabling flexible upgrades while maintaining a standardized physical interface.
