Last year I built my house and I have lots of conduit and wiring throughout. Everything works great except for one nagging issue.
My DSL router's connection seems to degrade over time. It gets to the point (after several months) where it can't even keep a connection to the PPP server. At that point if I cut off the phone cable ends and put new ones on it works fine again for another few months.
I have CAT 5 wire running to the phone box on the side of my house. I use two of the CAT 5 wires which run through the whole length of my house to the model. I have a RJ-11 coming off those two wires which plug into my router/modem.
We don't have phone service, just DSL so there are no filters.
Should I rerun the line from the phone box to my modem with higher gauge wire?
Any other ideas?
124 awg should suffice, it is the same gauge that carries the signal in the CO. You might rather look at getting higher grade copper instead, or better RJ-11 plugs. Another thing to look at would be your crimping method, do you crimp it with the a portion of the casing in the plug, or do you leave some exposed wire? Do you crimp twice to ensure a strong crimp? Do you secure the cable in any way after crimping and if so, with what method? Have you measured the DB loss on the cable? What pair on the cat5e cable are you using? How many termination points from the phone box to the modem/router? – MaQleod – 2011-10-03T21:31:50.757
I have a really nice ideal crimping tool and I don't expose the wire. It is a very strong crimp since it ratchets down. I just redid the connection today and I have pretty good numbers on the cable, but I'll check that if/when it starts going bad again. – Bryant – 2011-10-03T22:21:23.530
Phone lines should not run on CAT5 - Twisted pairs cause interference that causes performance issues on ADSL/DSL frequencies.(even though builder say its ok) twisted pair for voice is ok but on ADLS it causes electro magnetic resonance and if you go flat>twisted>flat.. you going to have performance issues.I have seend wires rusted and drenched in water, in an absolute state- and they work fine. something else is wrong in your installation. – Piotr Kula – 2011-10-04T12:58:32.467
It doesn't go Flat>twisted>Flat, just Flat>twisted. I tested the noise at both the box and at my router location inside the house and the noise level is the same. So I think the CAT5 seems to be just fine. – Bryant – 2011-10-04T16:00:46.380
Go to an auto parts place and get some "high voltage" clear silicone grease. This is intended for distributor caps. Put a tiny dab on the end of the cut cable before you crimp on the ends, and then put a tiny dab on the connector contacts before plugging in. (And, no, the grease DOES NOT prevent the connectors from making good contact -- quite the opposite.) – Daniel R Hicks – 2013-12-25T02:57:02.353
@ppumkin - Twisted pairs do not cause interference. The wire inside multi-wire telephone cables is twisted, precisely to prevent interference. – Daniel R Hicks – 2013-12-26T13:27:18.597
@DanielRHicks Yea- Sorry I re read my comment. What I meant was the phone signal, when active, call or ringing, might cause interference with the LAN side. If just using for phone then yea sure- that should be fine. But mixing is not recommended. – Piotr Kula – 2013-12-26T18:15:13.047
