Hello all,
an update on this issue,
today the network engineer came and the first thing he did was to make frequency measurements on the main connector. He immediately identified that there was an issue with the signal and he would need to open a ticket for the contractor to fix the cable and/or outer installation. (this sounds familiar, right? 😒)
if only this would've been reported the last time the technician came, it would have save us a lot of time and we might have some progress here...
Nevertheless, he performed additional measurements from the street cabinet to the main connector that would help him understand the issue better and add this information to his report.
Luckily, this time this information was reported accurately and we already received a confirmation from BAM Telecom BV that they will arrange an appointment to fix the damaged cable.
