T-REXFTTH GPON Test Lab Automation Solution

Automation Testing Saves time and Money. Tests have to be repeated often during CPE/ONU conformance and IoT cycles to ensure quality. Every time a modified FW is loaded in the CPE/ONU tests need to be repeated. Manually repetition is costly and time consuming while automated tests can be run over and over again at no additional cost and much faster. Automation can reduce the time to run repetitive tests from days to hours.

Description

FTTH Test lab automation: towards the path of excellence

Current certification process has a high portion of “Waste” (there are too many manual intervention and a lot of lab resources underused)
Manual execution of a Test Plan takes a long time (usually several weeks) where 70% of committed time is devoted to tasks with less value added (i.e. resources set up and test plan execution). Due to time pressure, there is a high risk of lack of dedication to tasks of greater added value that lead to a growth in the likelihood of “diagnostic error”

Current testing drawbacks

Inacuracy: Results not repeatable
Subjective: Unstable Test Efficiency
Days/TCs: Problems to meet deadlines
No TCs for stress: Poor Test Coverage

An automated testing tool is able to playback pre-recorded and pre-defined actions compare the results to the expected behavior and report the success or failure to a testing engineer. Automated tests can be easily be repeated and extended to perform tasks impossible with manual testing.

FTTH Test Lab Automation: Moving from WASTE TO VALUE.

The automation of all tasks related to resources set up, T-REX es FTTH GPON Test Lab Automationtest plan execution and test report generation has a drastic impact on Test plan completion time. What it took weeks, now are hours (less than one day). These savings in time will lead to a continuous pursuit of perfection (better Test Plans) and staff recognised professional roles (Test Plan designers and Test results analysts)

GPONDoctor Test Automation solution, T-REX is a powerful and affordable automated software-testing tool that is supported on all GPONDoctor products. It addresses the full range of CPE/ONU testing challenges that FTTH operators (QA engineers) have to deal with.

Drastic reduction in the Test plans execution times (hours instead of weeks)

Test execution capacity boost, by accurate faults identification leading to faster resolution times.

Repetitive tasks reduction like setup and execution enabling better Test Plans a Results analysis.

Improved process quality (reliable testing, robust against changes)

Lab resources integration (centralized control of all active network elements traffic generators, switches, power controllers, etc.)

Solutions

One Customer – One solution

GPONDOCTOR has been working with all the players involved in the FTTH GPON world since 2009. Our engineers have worked hand in hand with our customers’ technical engineers and learning from them what are their main concerns. They all share the same wish “have Testing done in an automatic way” but they all differ in the kind of Tests it should address.

Therefore, GPONDOCTOR has developed a family of products designed to meet all the needs of the FTTH GPON industry regarding Test Automation, GPONDoctor T-REX.

Broadband Connectivity Services (Access Network Providers)

Service Providers (IPTV, VoIP and HSI)

WholeSale Providers

They are the combination of a Network Service Provider (NSP) and an Application Service Provider (ASP) and thus providing Triple play services as well as connectivity pipes. GPONDoctor T-REX will provide them a combination Test lab for conformity, interoperability, and performance as well as functional for Service support.
For those with needs to launch new devices, services and network features as well as to improve the Quality of Service and Quality of Experience. GPONDoctor T-REX. can “help” to define Test Plans, requirements, device acceptance process, policies and procedures as well as Test environments.

GPON ONUs' Manufacturers

GPON OLTs' Manufacturers

GPONDoctor T-REX will help them to troubleshoot in Multi vendor environments, in order to verify other parties ONUs interoperability with manufacturer OLT products and Firmware releases.

No matter whether you are system vendors, Customer devices manufacturers or Application/ Network Services providers, your Test Plans will be automated by one of our T-REX solution. Just focus on tasks that provide value to your company, T-REX will take care of the rest.

How it works?

GPONDoctor T-REX is a Test automation platform that orchestrates a lab infrastructure topology where pre-defined Test plans are executed. Results are collected from all the testing elements involved and compared against validation criteria to determine a PASS/FAIL. Different level reports are also generated automatically.
how_it_works
GPONDoctor T-REX has two kind of users:

Automation Producers: From a pre-defined set of testing resources stored in the block repository, they are in charge in the implementation of the Test Cases that are part of each Test Plan to be executed by T-REX.
Automation Consumers: In charge to load Test plans into the system, schedule their execution and collecting the results and reports.

Physical Topology Orchestration

GPONDoctor T-REX will provide all the APIs needed to control all the devices involved in the Test Plan, including OLTs, Optical Matrix, Switches, Traffic Generators/Analysers, GPON Analysers, Variable Optical Attenuators, IP Power units, ONUs/ONTs, Home Gateway Units, CPEs, ACS and many others. All of them are controlled from a central server and will be provided with the proper configuration according to the specifics of each test case.

Test Execution Orchestration

Once the Test Plan is loaded in the system, GPONDoctor T-REX will get from the Configuration Repository the devices involved in each Test Case as well as the Validation Criteria. It communicates with the Topology orchestration module in order to setup all the devices involved accordingly while the Test Case is been executed. All the data generated during this process is analysed and compared with the expected results and finally a report is generated and stored in the “Results Repository” together with the analysed data. Once a Test Case is completed the next will be executed until all associated to the Test Plan loaded are finalised.
