Phone use kills DSL connection, even with whole-house splitt |
|
|
Well, I installed a whole-house splitter, thinking that my problem was
with the dongle-type splitter that my ISP provided with DSL modem; but
using the phone on the same line that the modem is on still terminates the
DSL connection.
Details:
Phone service is Verizon, via UTP wiring installed to my apartment within
the last two years. Wiring on the Telco side in the NID is sort of
haphazard (wires not twisted right up to the screw-terminals), but I'm
reluctant to mess with them. Screw terminals have red and green wires to
the gray module in the NID that has the user-side screw terminals (also
red and green).
I've used a Cat5 cable to connect each of the two phone lines in the NID
to a 2" x 3" electrical outlet box just below it, containing (only)
Leviton snap-in RJ-12 jacks; done carefully, with spade connectors on the
NID side, punchdown on the jacks.
Cat5 cable with RJ-12 plugs connecting the DSL line from jack to a Wilcom
PS-15 whole-house splitter.
Cat5 cable, again with RJ-12 plugs from splitter to DSL modem. Linksys
WRT54G wireless-capable router (wireless disabled) connected to DSL modem,
and serving our home network (again, all Cat5).
All phone wiring downstream of splitter is Cat5, installed by me, and star
topology, though that doesn't matter, since I get the same results if I
connect our phone direct to Wilcom splitter. I can get dial tone, and
dial, without losing the DSL connection, but as soon as ringing begins on
the line being called, the connection drops. DSL light on modem relights
when phone use is complete, but it takes awhile for the router to
The phones we're using are 2.4 GHz wireless models, if that makes a difference.
Can anyone hazard a guess as to what might be causing this, despite my
best and careful efforts? I was vigilant to keep to the USOC and T568A
color codes while making up connecting cables, but I might have swapped a
tip/ring pair in the phone cables; could that cause this annoying problem?
Thanks,

The DSL modem connection works fine with all the phone wiring and splitter
disconnected.
Likewise, the phone works fine without any splitter, when hooked up to the
line alone, without the modem.
I'm not going to hook up modem and phone to the same line without any sort
of splitter, because the splitter is intended to protect the modem from
phone interference, and vice versa I don't see the diagnostic point of
not using a splitter, when there's bound to be interference without a
device protecting modem, and phone.
Contrary to indications given in my prior post: When modem and (only one)
phone are both hooked up, using the whole house splitter or the smaller
dongle splitter provided by Earthlink, and leaving the router unconnected,
the behavior is the same: as long as the phone is not used, everything
works fine. When the phone is picked up (dial tone), the DSL modem seems
to keep connected (DSL and ACT lights lit solid) for about 20 seconds,
but, no matter whether the phone is hung up, or dialed, the DSL light will
eventually go out. Putting yet another dongle (with only one input and one
output) on the phone line downstream of the splitter does nothing at all
to help.
The fastest way to restore the DSL connection is to turn off modem and
router, reboot modem; and when DSL and ACT lights come back solid,
reconnect the router. However, the system will eventually reconnect on its
own if left unattended to, with everything hooked up.
It looks like I'm just going to have to have my DSL service connected to
our second line, rather than the main phone line. I had hoped to
unsubscribe the second line when we stopped using modems, but I guess
that's just going to be part of the cost of having DSL.
Thanks,

We just got Earthlink DSL service, installed it myself in a closet
containing
Verizon NIB (in an apartment) served by UTP
our own Linksys router (wireless + 4 ports) for star-topology Cat5e home
network
Earthlink's Zyxel DSL modem
Phone bridged block to star-topology Cat3 phone wiring to all phones
Phone service is wired through the DSL/phone splitter dongle that
Earthlink provided, and thence to modem (one Cat5e cable), and all the
rest of the phones in the house (another Cat5e cable). Everything hooked
up and connected without a hitch,
BUT:
whenever the phone line is used (incoming or outgoing call) the DSL
connection (ACT and DSL lights on modem) craps out. Once call is
completed, the DSL light comes back on, but the router doesn't reliably
reestablish the connection automatically though it will sometimes.
Diagnostics performed at this point using Earthlink's Setup URL indicate
that PPPOe fails. Power cycling the router only works occasionally, but
the most reliable way to reestablish the connection is to power cycle
both
modem and router.
I realize that I should probably have a more expensive whole-house
splitter, and I'm willing to buy one, but it surprises me that the DSL
service quits, while there's no noticeable static on the phone line. So
is
the fix that simple, or do I have some networking
hardware/software/protocol issue too?
Note: I didn't buy Home Network service from Earthlink (comes with the
same router I had already, and costs another $8 per month). Is there
something in that package that I "need to have" for DSL sanity?

Let's not overlook the "obvious" here.
Before you waste a LOT more time and money, I strongly suggest you get a
hard-wired phone to test with. Your problem might be RF interference from
the cordless phones, especially if the base unit is located near the
modem/computer.
A recent thread (in this group, I think) from a ham radio operator ended
with him getting a different modem. His first one was apparently overly
sensitive to nearby RF sources.
Good luck! |

Well, this is very odd and must be frustrating.
It sounds like a bad connection (wiring/contact) somewhere.
Increased current from POTS kills DSL -- somehow, because
I've heard of people whose POTS was broken but still had DSL.
How good are your services? DSL speed & voice volume
(through a passive set)?
A wiring defect could easily be the Telco side, but before
calling (& potentially paying for a truck roll) you should
check out your premises wiring:
Reseat all connections at the NID, disconnect house and run
single line to unpowered phoneset & your modem with Y & dongle.
See if misbehaviour repeats. If so, premises wiring is likely
not the fault, and time to call telco.
When you do this, make sure you've cut parasites
like alarm systems out of the loop.

The DSL modem connection works fine with all the phone wiring
and splitter disconnected.
Hi Charles... This is normal and expected.
Likewise, the phone works fine without any splitter, when
hooked up to the line alone, without the modem.
This is also normal, despite the things I've been told that the DSL
signals should be heard through the phone. I've never heard this
ever on any of my phones. Although I suppose some phones can hear
them.
And what you call a splitter is actually a splitter/filter. Thus
everything that plugs into the phone line with the exception of DSL
and Home PNA equipment, gets this splitter/filter. This includes
fax, dialup modems, and even CallerID boxes.
The part of the splitter/filter that is marked DSL is actually a
straight shot without any filtering at all. So it is really like it
isn't even there to the DSL modem. Thus this line (or a line before
the splitter/filter) must go to the DSL modem without any filtering.
I'm not going to hook up modem and phone to the same line
without any sort of splitter, because the splitter is intended
to protect the modem from phone interference, and vice versa -
I don't see the diagnostic point of not using a splitter, when
there's bound to be interference without a device protecting
modem, and phone.
Actually the splitter/filter attenuates any frequencies above
something like 5K HZ or higher. Which are the DSL frequencies up to
1MHZ if I recall correctly. The DSL modem also gets the voice
frequencies as well, but it doesn't care about them and it is
ignored within the DSL modem itself. Not externally with a
splitter/filter combo.
Contrary to indications given in my prior post: When modem and
(only one) phone are both hooked up, using the whole house
splitter or the smaller dongle splitter provided by Earthlink,
and leaving the router unconnected, the behavior is the same:
as long as the phone is not used, everything works fine. When

but, no matter whether the phone is hung up, or dialed, the DSL
light will eventually go out. Putting yet another dongle (with
only one input and one output) on the phone line downstream of
the splitter does nothing at all to help.
Two things can cuse this. One the phone isn't on the splitter/filter
like you believe it is. Or the DSL is also on the splitter/filter as
well. Which may work (without a phone picking up), but DSL
connection speeds will be terrible. Somewhere around dialup speeds
is my guess if it works at all.
The fastest way to restore the DSL connection is to turn off
modem and router, reboot modem; and when DSL and ACT lights

Nope you don't have to use a second line for just DSL at all. And
that would be a waste of money anyway. It just sounds like to me
that your wiring (may include splitter/filter) is hooked up wrong.
There is a possibility that your splitter/filter and/or DSL modem
is/are faulty. But I seriously doubt that yet.
Cheers!

Ours is installed right next to the NID, and all phone wiring in the

All I know is that on the splitter/filter, incoming service is plugged

plugged into the PHONE jack. And it makes no difference if I use the
Earthlink supplied splitter/filter (dongle) or the new whole-house filter

There is one more thing about our installation that I forgot about until
the doorman rang up to say our pizza delivery was coming -- our building
uses the phone as an intercom service, but not in the normal sense. You
dial *45 on the phone and hang up to send the doorman an attention signal
, and then he calls up, again using the phone line. And to announce people
from the outside, he again calls up, and the phone has a peculiar ring
(longer than normal, two in a row). So there's some equipment in the
building that interfaces with the phone lines, I don't know how.

DSL is not great, but okay. I'm paying for premium speed from Earthlink,
"up to 3 Mbps" rather than "up to 1.5" and getting 700 Kbps to 1.4 Mbps. I
don't notice any real static on the phone line with the 2.4 GHz cordless
phone, though when someone calls from across the street, the volume is
louder than when we get an out of town call. Is a "passive set" something
without a power adapter?

As I think I said before, the wiring on the Telco side of the NID is not
twisted right up to the terminals where the red and green wires to the
user side module attach. I'm loath to play with these, since I lost a
phone line (the one in question) for a couple days when installing wiring
for the rest of the house and connecting it to the Telco wiring at the NID
(must have shorted for awhile). The Telco had to make a visit to restore
service then.
From NID to outlet box with RJ-12 jacks, I've replaced all the wiring
since beginning with this problem, and I don't think there's a poor
connection there. The only wiring I haven't changed is the cable from the
filter to the modem, which is a Cat5 cable that I put RJ-12 connectors on
(because that's what the filter and modem have for jacks).
I'll borrow a non-powered corded phone, and try that. I'll also try
another cable between modem and filter.
Thanks for the help,

Some voices might, but the telephone won't go up that high. I seem
to remember up to 3KHZ. Ever notice some people sound different on
the phone? Ever hear a talk show on the radio with a caller on the
phone? Doesn't the phone caller sound poor even on low quality AM
radio? Which if I recall correctly, is only good up to 8KHZ.
| Quote: | I was under the impression that the filter also attenuated the low

I don't think so. As you can connect up those splitters/filters
backwards, meaning the incoming line and the DSL is switched. And if
there was a filter on the DSL marked connection, the phone output
would be attenuated and it wouldn't work on the phone line. But it
does. So I believe it is all a straight shot except on the phone
output of the splitter/filter.

I never heard of a filtered phone not working with DSL yet. Although
maybe some phones don't work well for all I know. Being a retired EE
though, that phone would have to really load (almost dead short) to
cause that sort of problem though.

This doesn't sound good. As it sounds like their telephone
switchboard thingy may need a filter on it as well. So when you pick
up the phone, so does the building equipment. So it acts just like
your phone isn't filtered. Does that other second line also go
through their equipment? Or is that one bypassed?

How good are your services? DSL speed & voice volume
(through a passive set)?
DSL is not great, but okay. I'm paying for premium speed from Earthlink,
"up to 3 Mbps" rather than "up to 1.5" and getting 700 Kbps to 1.4 Mbps. I
don't notice any real static on the phone line with the 2.4 GHz cordless
phone, though when someone calls from across the street, the volume is
louder than when we get an out of town call. Is a "passive set" something
without a power adapter?
A wiring defect could easily be the Telco side, but before
calling (& potentially paying for a truck roll) you should
check out your premises wiring:
Reseat all connections at the NID, disconnect house and run
single line to unpowered phoneset & your modem with Y & dongle.
See if misbehaviour repeats. If so, premises wiring is likely
not the fault, and time to call telco.
When you do this, make sure you've cut parasites
like alarm systems out of the loop.
As I think I said before, the wiring on the Telco side of the NID is not
twisted right up to the terminals where the red and green wires to the
user side module attach. I'm loath to play with these, since I lost a
phone line (the one in question) for a couple days when installing wiring
for the rest of the house and connecting it to the Telco wiring at the NID
(must have shorted for awhile). The Telco had to make a visit to restore
service then.

AFAIK (as far as I know), all telephone lines are fused (or have a
resistor). And I think some of them are fused at the pole (or
underground). So this is probably what happened when they
accidentally got shorted. Others have a resistor in series which
limits the amount of current one can draw. So a fuse isn't really
necessary in this case.

since beginning with this problem, and I don't think there's a poor
connection there. The only wiring I haven't changed is the cable from the
filter to the modem, which is a Cat5 cable that I put RJ-12 connectors on
(because that's what the filter and modem have for jacks).

I won't think this would be a problem. But something to rule out.
But you did rule this out already, right? Another thing is some
phones will work if the lines are reversed (red and green lines
reversed). And some will not. And I don't know if DSL modems would?

another cable between modem and filter.
Thanks for the help,

I'd be curious what happens for sure. Although if the building
phone/intercom equipment is ruining your DSL signal, that isn't
good. As you probably would then need a splitter/filter between the
telco and their equipment. And run your DSL straight from there. If
this is indeed the problem.
Cheers!

Well, there you go, there's some "phone equipment" on the line before
the splitter, and when it's in use, it kills the DSL signal.
You need to get the building folks to put the splitter on your line
_before_ it hits anything, and take the "DSL" feed and run a separate
wire all the way up to your apartment where it'll connect to the DSL
modem. |

Well, duh.
The splitter must go on the phone line where it comes in *from* *the*
*telephone* *company* before any other equipment.
