PBX Configuration Validation and Error Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing administration tools for enterprise telephone switches, particularly those integrating traditional PBX with IP telephony features, are difficult to use and lack efficient validation and error resolution mechanisms, often requiring specific user training and failing to ensure accuracy of configuration changes.
Innovation Solution
A comprehensive administration tool that validates configuration data by detecting errors against syntactic and conflict rules, provides user interfaces for error correction, and automatically updates affected data objects, with features like error trees and auto-fix capabilities to streamline the administration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration data is entered without validation, then the administration tool is simpler to use, but the accuracy and reliability of configuration changes deteriorates
Solution Approach 1:
The patent applies preliminary action by validating configuration data before it is applied to the switch. The administration tool checks configuration parameters against defined rules (syntax rules, conflict rules, inheritance rules) prior to implementation, ensuring accuracy is maintained without requiring complex real-time validation mechanisms during operation.
Solution Approach 2:
The patent implements feedback by providing users with detailed error messages and guidance when configuration validation fails. The tool identifies specific errors, their locations, and suggested corrections, allowing users to fix issues efficiently. This feedback mechanism maintains high reliability while keeping the user interface straightforward.
2Reliability
If configuration changes are allowed without error checking, then the administration process is faster, but the reliability of the system deteriorates
Solution Approach 1:
The validation process is performed preliminarily before configuration changes are applied. The administration tool checks all configuration parameters against multiple rule sets (syntax, conflict, inheritance) in advance, so that when users apply changes, the system already knows if they are valid. This prevents time-consuming runtime errors and ensures reliability without significant time loss.
Solution Approach 2:
The system provides self-service validation where the administration tool automatically checks configuration data against defined rules and provides guided error resolution. Users receive automated feedback about their errors and can correct them directly in the interface, reducing the need for manual system checks and maintaining both speed and reliability.
3Reliability
If validation rules are added to ensure accuracy, then the reliability improves, but the ease of operation deteriorates
Solution Approach 1:
The patent implements comprehensive feedback by providing detailed, location-specific error messages when validation fails. The tool identifies exactly which parameter is incorrect, why it violates the rule, and often suggests the correct value or format. This targeted feedback maintains high reliability while keeping the user experience simple, as users only need to correct the indicated errors without navigating complex validation logic.
Solution Approach 2:
The system changes the state of configuration parameters through validation and correction. The administration tool tracks parameter values against defined rules and provides guidance for correcting invalid values. This parameter-based approach ensures accuracy while maintaining ease of operation, as users interact with familiar configuration interfaces rather than complex validation mechanisms.
4Manufacturing precision
If comprehensive validation rules are implemented, then the manufacturing precision of configuration data improves, but the device complexity increases
Solution Approach 1:
The validation system is segmented into distinct rule sets: syntax rules for parameter format validation, conflict rules for detecting parameter conflicts, and inheritance rules for template-based validation. Each rule type operates independently and can be maintained separately, making the overall system manageable despite the comprehensive validation coverage. This segmentation achieves high precision without excessive complexity.
Solution Approach 2:
The administration tool provides universal validation functionality that works across all configuration parameters and switch types. A single validation framework handles multiple validation types (syntax, conflict, inheritance) and applies to various configuration objects (voice ports, data ports, users, groups), reducing overall system complexity through reusability while maintaining high precision through comprehensive rule coverage.
Data Source
AI summary
Methods and apparatus are provided for validating configuration data in a switch. An error is detected if the configuration data fails to comply with one or more rules; and a user is presented with an interface that allows the user to correct the error. The rules may include one or more syntactic rules or conflict rules (or both). In the case of a simple error, the user is presented with an error indication with a smart error link. In the case of a conflict error, the user is presented with an error indication that identifies the conflicting endpoints and optionally allows the user to correct at least one conflicting endpoint. The configuration data is revalidated after a change is made by a user. Changes are propagated to affected data objects. A number of error types may be automatically updated. When an objects inherit properties through application of a template to the data object, a list is maintained of the data objects associated with each template, so that the associated data objects can be updated if the template is updated. Errors information can be presented to the user in a hierarchical error tree. The user can select errors from the tree to be corrected. The error tree can optionally be redisplayed following a change by validating only affected elements.
