Bonded DSL connection and extended phone wiring
Bonded DSL connection and extended phone wiring
The ISP should have connected the wires directly at the jack. It's strange you believe this is okay. You're using a crossed pair, placing them within the interference zone and running them side by side until they fail. The noise from the line will be excessive. They must connect the wires to the jack and twist the pairs. The jacks need rewiring so the modem can be moved. Adding another cable isn't the answer.
It took some time to understand your solution, but I believe I now grasp it. The phone jack rewiring you needed involved merging those two phone lines into a single internal connection inside the jack, rather than using that unusual spliced cable. This allowed me to run a standard, long phone line from the jack directly to the modem without problems, while still maintaining the DSL speeds. Your ISP only has one technician nearby, and he’s known for being unreliable—he didn’t understand my ping times or what I was discussing. Perhaps this whole situation stems from his lack of proper rewiring skills and reliance on the subpar cable.
Although technically feasible, the ISP won't connect the jack directly from installation. They'll rely on cabling supplied by the modem maker instead of creating their own or altering their engineers' work (which isn't too complicated). I was present during early testing of bonded DSL for business clients in the UK, and most manufacturers who participated asked for the provided cables. ISPs don’t bother making end users’ cabling look tidy—they really don’t care. In our tests, only one Netgear model had a combined RJ11 port on the modem side with two copper pairs built in. Most older gear featured two RJ11 connections at the back, expecting customers to have two NTE sockets and run two separate cables. The bonding and routing were handled entirely through software on the modem.
Correct wire connections improve signal quality by adding more twisted pairs and allow flexibility for moving modems when needed. All our bonded devices are connected directly at the jack. This approach is standard now, unlike older setups with separate pairs. Previously, issues arose from troubleshooting, but since then there have been no problems. ISPs prioritize this setup because it meets their requirements. Most modern modems support VDSL and show bonding indicators in the port, making it easier to splice connections if needed.
