A protocol tester in telecom networks is a professional who tests and verifies the functionality and performance of various network protocols, such as 4G, 5G, LTE, VoIP, and IMS. A protocol tester is responsible for ensuring the quality and reliability of the network communication and services, by detecting and resolving any issues or problems in the network protocols.
Some of the roles, functions, and responsibilities of a protocol tester in telecom networks are:
- Designing, developing, and executing test cases and scenarios for various network protocols, using different test tools and methods, such as QXDM, QCAT, QDART, QPST, QMIC, and others.
- Analyzing and interpreting the network signaling messages and data, using various analysis tools and techniques, such as QCAT, QXDM Professional, QXDM Analyzer, and others.
- Identifying and reporting any defects, errors, or failures in the network protocols, using various defect management tools and systems, such as Jira, Bugzilla, TestLink, and others.
- Collaborating and communicating with other network engineers, system engineers, and protocol developers, to resolve any issues or problems in the network protocols, and to provide feedback and suggestions for improvement.
- Updating and maintaining the test documentation and reports, such as test plans, test results, test logs, and test metrics, using various documentation tools and formats, such as Word, Excel, PowerPoint, and others.
