Ingress Repair Management

Optimization of the ingress control program

Project Start:
In progress

This project, which started in June 2005, has to date been renewed annually. It enabled Vidéotron to obtain permission from Industry Canada to use aeronautic channels and reduce the number of service calls and cases of ingress to be repaired. It also allowed to maintain the network as required by the RPR-8 standard.


In order to obtain permission to use the channels reserved for the aeronautical radio-navigation band, Vidéotron had to maintain the CLI (cumulative leakage index) index) below 64. To meet this requirement, the company set up an ambitious detection and repair program for the signal ingress points in its networks. After having chosen Effigis to carry out the audit patrols of its networks, it chose to install DRV1 ingress detectors in its vehicles and those of its subcontractors. Since the amount of leakage to be repaired was considerable, Effigis was hired to set up a strategy and a leakage control program, and to oversee the work on a daily basis.


Few people believed that Effigis would be able to deliver on this large order. Therefore, we had to have the necessary resources to obtain as quickly as possible the use of the channels. Moreover, cost follow-up and a quality control program were to be set up. The client had to be informed ahead of time of work progress both dynamically and in real time.


With its solid experience in cable communications, Effigis formed a team of more than 25 technicians specialized in detection, location and repair of leaks. To do so, Effigis partnered with SC-360. SC-360 had in-depth experience in cable distribution. As for Effigis, creator of the CPAT technology, it was able to set up an effective distribution and daily follow-up system for work. The client could consult in real time the results of actions carried out via the CPAT Web site in the form of maps or spreadsheets for monitoring purposes.


Since the approval by Industry Canada had a major impact on the services that Vidéotron offers to its clients, it was urgent to correct the situation. Thus, in under one year, Vidéotron reached its goal. The project clearly showed Effigis’ ability to effectively carry out a large-scale project. The technician team dropped from 30 to 8, and annual costs fell by 40% from those allocated at the height of the program. The CLI is maintained below the allowable limits for each Vidéotron network.

Key takeaways

  • Ability to carry out large-scale projects using flexible innovative solutions
  • Working with a partner to optimize the program deployed
  • Reaching objectives after one year and maintaining the network to be compliant with the RPR-8 standard
  • 40% reduction in annual costs and fewer staff on site
  • Real-time consultation of results by client using the online CPAT tool
