[Communications] - Assuring QoS/QoE with the Deployment of an Optical Network Monitoring System in Movitel (Mozambique)
In early 2015, Movitel had possessed the largest mobile infrastructure in Mozambique, of which, the optical backbone played a critical role. The network expansion over the 2nd largest country in Africa raised big challenges to Movitel in maintaining the quality and connectivity of its optical network, and through that, to assure the QoS/QoE of its service delivery. COMIT’s engineers spent a few months in Mozambique and deployed successfully an Optical Network Monitoring System based on Viavi’s solution. The system has helped Movitel shorten the troubleshooting time, forecast the quality decline of optical links and initiate preventive solutions. It has also helped Movitel manage its resource more efficiently upon useful statistics and data generated.
[Communications] - Perfect After-Sales Service
In March, 2017, Movitel – the largest service provider in Mozambique had troubles monitoring 3 nodes OUT from a server of ONMSi system, and some of the other nodes were also unstable. Each node was responsible for tracking 24 cable lines which provide the transmission to the customers. As a reason for the incident, the quality of Movitel telecom network could be declined, and took time as well as many resources to overcome.
At that time, Movitel and COMIT did not remain any service level agreement. However, facing up with the emergency of customer, COMIT, with the spirit of “Devotion to customer”, immediately formed a support team to help Movitel solve the problem. With extensive experience in telecommunication testing and measurement, very soon, COMIT’s technical experts found the solution that examined, then re-enumerated the monitoring status of each node, and defined which error could be occurred. The Team worked hardly and continuously in three weeks notwithstanding time zone difference, poor connection, no days off, staying up late, waking up early…The problem of Movitel was solved quickly, all the nodes worked smoothly to track and ensure the transmission of the network.
Moreover, that was not even where the “Devotion to customer” spirit stopped. After helping the customer troubleshoot the emergency incident, COMIT provided free advanced training courses for Movitel engineers on issues when using the products and solutions.
"Devotion to customer" is one of the core values of COMIT since establishment, and despite any difficulties, customers can trust that COMIT will always be together to find solutions.

[Manufacturing] - Connectivity solutions of HMS Networks for an Australian F&B company – Dairyworks
Dairyworks source high quality, bulk cheese and butter from local South Island suppliers and package it into consumer products for supermarkets, convenience stores and other retail outlets throughout New Zealand and Australia.
Dairyworks acquire the weight data for reports in real time from a numbers of checkweighers in throughout the factory. Some applications required local PLCs to know product weights for process indication and control. Dairyworks use the Modicon M340 PLC for automation and data control.
This unit is, a powerful and versatile PLC however did not have native support for the ASCII protocol over Ethernet TCP/IP.
Dairyworks solution was to use an eWON 500 to get weight data from all of the checkweighers over the Ethernet TCP/IP connection. We used the eWon script to control/report status of data connections, receive and reformat weight data, tag and store in eWON memory.
The PLC, using Modbus TCP, reads and writes to the eWON memory to get the data it needs and control and test data connections.
The solution is simple, rather inexpensive and has proved reliable. It allows data to be shared on PLCs and HMIs allowing the operators live access to meaningful graphically presented production data.
[Manufacturing] - Quality Assurance for TOYOTA - ATS Inspect solutions
The Toyota Quality Division involves vehicle inspection cells, including drum test, wheel alignment, shower and Customer Satisfaction. Toyota’s objectives were to record and report every single defect, in real time, and alert Quality Managers when serious issues arise by email and SMS.
The ATS Inspect system works as follows. When a vehicle enters the inspection cell, the operator scans the barcode VIN (Vehicle Identifier Number). This vehicle then appears on the system. The Quality operator inspects the vehicle and records any defects found in ATS Inspect using a touch screen.
Any vehicle with defects that cannot be repaired in the Inspection Station is moved to the Hanedashi area (repair area). When the vehicle enters the repair cell, an operator scans the barcode VIN again. ATS Inspect then displays a list of all defects recorded for that vehicle. When rectified, the operator uses ATS Inspect to record that the defects have been repaired.
Real Time Reporting:
A key benefit of ATS Inspect is its ability to feedback information to operators and management alike in real time. The ATS Inspect database structure allows for reporting in any form required. This means that management can review the defect trends and prioritize resources accordingly while the operators can drill-down into the information to see exactly where problems are occurring.
Using ATS Inspect, Toyota has achieved the following:
- A continuing reduction in the number of average defects per month from ± 20.000 to ± 5.000, and dropping
- Removed all paper in the Quality Control Division
- Reduced the number of resources involved with quality data gathering and reporting (retrained and moved in organisation)
- Real time feedback on issues
