The cables in the wall are probably insulated too.
Sure. So is your phone line cord.
Not as well as cat 3. I suspect that is what make the cable in the |
wall.

Yes, they have a news server.
There news server coverage is better than at the university campus

Oh well. There goes the pr0n. But as a friend says, it gets boring |
very quickly. I'm just interested mostly in technical groups. |

Not a 5100x, but a Westell Wirespeed. How many LEDs does it have? As a one-
time hardware tech, repairing assemblies in HP's mini-computers, then
desktop workstations, I see four LEDs. Looking it it as somebody who doesn't
know any better, only three of them are lit. (No big download going on at
this time; the Ethernet link activity LED is mostly quiescent.) I suspect
the average user is thinking of lit LEDs, not all LEDs.

| Quote: | Despite what everyone else has said, the cable from your phone jack to the
modem is ***NOT*** ordinary phone cable. Ordinary phone cable will work but
is susceptible to interference and perhaps speed reduction. As you noted,
it looks different. It is round instead of flat (am I correct?). It does
have the same RJ-11 plugs on the end so that it is physically
interchangeable with phone wire, but it is CAT-3 TWISTED PAIR wire which is
what you should be using for your extension.
|
Um, I damaged the modular plug on the round wire which came with my Westell
Wirespeed. I replaced that with a shorter run of flat satin phone cord with
no trouble. I am getting the same speed on tests as before reworking the
wiring here. The biggest change was to add a POTS splitter, one of the
Siecor exterior versions, in place of the microfilters. And I replaced the
original, 40-year-old phone run from the NID to the computer corner; 16
gauge two-pair, with no apparent twist was replaced with a like length of 26
gauge CAT 3 two-pair. Earlier this summer, as a result of voice problems,
the phone guy replaced the NID, a two-line model with test jacks, in place
of the 40-year-old carbon block one-line model. And he also replaced the 40-
year-old one-pair, parallel, 19 gauge drop with a new three-pair, twisted,
26 gauge drop. I can't say my speed is better, I can say it isn't worse.
With nearly 100 feet of new, 26 gauge twisted wire in place of older,
heavier gauge, untwisted wire, I somehow don't think that a 7 foot flat
satin cable in place of the 10-foot twisted cable that came with the modem
is a big hit. Not after that signal came 10,500 feet from the C.O., through
a "B-box", to the premises.

No amplification, that I can see, here. The new box the phone guy left can
handle two lines, though we have only one, and has a test jack. I watched
the tech install it; even had him not worry about the second anchor screw.
When he had the cover off of the company side of the box, it didn't look
much different, physically, from the old carbon block he removed. It is
electrically different, apparently, from what the tech said; but I don't see
any external power source, which I am sure is necessary for amplification.
