- Test integrity of RJ45 panels to RJ11 connectors on the Jontek server in the small comms room (passed)
- Test integrity of RJ45 panel in small comms room to main DP in PBX room (passed)
- Test integrity of copper pair from PBX room to BT Exchange (passed)
- Tone from BT Exchange to RJ11 patch lead in small comms room (failed)
- Push down DP connectors in the small comms room had been reversed by previous engineer between lines 1 & 4
- This was reversed, upon which Line 4 came back and Line 1 went down
- Line 1 - retested and repatched in PBX room to new copper pair back to the exchange
- Line 4 - new connecting copper pair in exchange connected to Line 4 on the dialling number
- RJ45-RJ11 patch reconnected on Jontek server
Relabelled CCTV / Helpline Patch Panel
One of the patch panels in the small CCTV / Helpline comms room was badly mislabelled - the ports on the incoming panel do not match the ports on the connecting panel to the Jontek server.
We've repatched the jumper leads so that they do now match. The grey connecting cables between the patch panel and the Jontek server have also been labelled correctly.
Warning / Point to note for future
The whole system is built on old, undocumented, extremely complex main incoming copper, plus copper extensions (for which Openreach is not responsible), connected to plug types that are not used for voice connectivity (RJ45 network sockets). Given the age and fragility of the copper wiring, moving to an alternative system is now very urgent.
