DSL = Digital Subscriber Loop. That meant something decades
ago, but now DSL is just a name.
The difference between DSL and cable modem technolgies is
that DSL is baseband - if you're sending 10Mbit of data,
you have a 10Mbit signal on the wires. Cable modem uses
a radio frequency carrier which is modulated with the 10Mbit
signal. Both are analog technologies.
The problem with DSL is it's _very_ dependant on the quality
of the connection it goes over. If you have fiber all the
way to the house (very uncommon) you get excellent results.
If you have twisted pair part of the way (the normal case)
you get indifferent results - mostly because the twisted
pair is usually ancient and in pretty crappy condition.
Now, as far as landline phones go, if the phone puts the
voice signal directly on the wire, that is what's called
"analog landline". If the phone converts the voice signal
to digital data, and then sends it over either DSL or
cable (where it's an analog signal) it's called "digital
landline". If that digital data is additionally formed
into IP packets and sent over the Internet, then it's
(who doubts anyone really cares about the technical
side of phone lines...)
UVerse works on pure fiber, fiber to the node, or in some fring areas
DSL multiplexing. It is not the same as ordinary single-line DSL.
No, it is a technology. People who don't know any better might call
their cable connection "DSL" or their fiber optic connection "cable" but
the people who install it certainly know the difference.
Nope. DSL has multiple 4.3 KHz carriers on adjacent bands going from
somewhere between 10 and 100 KHz up to whatever limit the particular
loop can carry. If it's carryine 10 Mb/sec it multiplexes that data
over however many channels are required. But it's bloody rare for DSL
to hit a speed that high.
The technology on which DSL is based.
I've never seen a DSL connection with phone service in which it is
necessary to plug the phones into some kind of converter box in order to
use them. The filters are needed to make the DSL work, not the phone,
and they do not do signal conversion, they simply isolate the frequency
DSL with phone uses analog phone service. There may be a repeater at
the street that moves the CO closer to your location, but your
connection is analog to the CO.
And why would a cable company use analog phone signalling? That would
just add complexity to their system and tie up bandwidth that could be
used for other purposes--you seem to have DSL and cable reversed in your
I have comcast triple deal, phone, internet and TV. We only have the LL
because it's cheaper than with out it. We've had the same LL phone
number forever, so we also for some ungodly, unknown reason, are
attached to it. We rarely ever get calls other than salesman,
politicians and so on and they are switched to an answer machine after
two rings. I keep telling my wife not to answer the thing, everyone we
know calls our cell phones, but she can't resist, which of course
results in more calls.
I tried to use the PhoneTray thing-ee as it looked perfect for what I
wanted, but it doesn't work with Comcast, it needs a voice modem. I was
thinking of trying out a cheap voice modem, found a bunch for under $15,
but not sure if that would work or not. Has anyone used something like
this with Comcast? I have an old USRobotics Modem in my shed from the
pre-internet days, but I don't think I want that answering calls, or
maybe I do. Not sure I know what a "voice modem" is?
Add Life to your Days not Days to your Life.
For what it's worth, when I switched over to Tracfone, I took my
landline number with me. One just has to wait a day or so for Comcast
to release it (Tracfone will take care of the details). That said, I
noticed yesterday that the price of Tracfone minutes has gone up 17%
over the last few months. I'm still come out far ahead this way. If you
spend a lot of time on your phone, your mileage may vary (but you can
compute it in advance and see!)
I haven't had a landline phone in almost a decade. We had a line
once, because they refused to sell "naked" DSL (required a phone line)
but there was never a phone attached to the line. About a year later
they allowed us to drop the phone "service".
My daughter just switched from dish to comcast. They never owned a
phone other than cell. She gets the comcast triple play as I do,
because it cost MORE not to have the LL. Her phone line ends with
nothing attached, nothing to ring. People under 40 have no use for old
style phones, and neither do people over 40, but old habits are hard to
break I guess. I probably should just disconnect my LL so no more
salesmen, politicians etc. but for some dumb reason, we haven't been
able to do it. When I say "we" I mean my wife.

I almost dropped the land-line. If it wasn't for AT&T's lack of signal
where we live, I would have.
Actually, AT&T has this thing called something like "wireless home
phone" or something like that. It's cellular in nature, but looks and
feels like a home phone. They suggested that when I was making a few
We dropped our landline a number of years ago. My wife and I each have
a cellular phone with good signal strength at home.
We still liked the "convenience" or familiarity of the land line
cordless phones so, after disconnecting from the grid, I installed a
Siemens Gigaset Blue Tooth unit.
You connect the Gigaset to your house wiring and a wall wart for power.
Once programmed, once you enter the residence with your cell phone the
phone is automatically linked via Gigaset and you can make and receive
your phone calls using either a traditional POTS hooked to the household
phone wiring as in days of yore, or just use the cordless handsets.
The Gigaset we have is capable of simultaneous connection with three
cellular phones and when you call out, you can select which cell phone
you use for the call or let it default to the phone connected at
Siemens is not the only such device out there. Panasonic, in fact,
makes a cordless phone set with this technology built in that you can
use with either the regular wired landline and/or the cellular BT feature.
Really nice not having to carry the cell phone around with me in the
house. If I'm out in the shop - separate building from the house -
there's a cordless phone on the wall.
OTOH, what Puckdropper wrote about from AT&T (and Verizon Wireless
offered a similar deal) requires you to pay a monthly fee to the
carrier. Nuts! I paid about $60 for my Siemens unit. The carrier will
sock you $20 a month or so for that convenience. LOL!
We have the ATT wireless phone. It is cellular and shows up like
another cell phone on the ATT cell phone bill.
You get a cellular receiver that looks like a wireless modem and it
plugs in to our cordless phone transmitter/message machine.
The ring is distinctly simple and no FAX.
The sound is as good as regular land line.
BUT with taxes, fees and so on it comes out to between $25~$26 per month
and we are about to drop it as almost the only calls we get on it are
It is a good deal that works well but we don't need 3 phone numbers for
Yeah, my wife got tired answering politicians' robocalls so didn't
fight when I wanted to dump the phone. I kept one in the kitchen
drawer for a while if she felt she needed to call someone on a land
line she could plug it in. ;-)
I still get political robocalls once in a while but usually for pols I
couldn't vote for if I wanted (different state and I'm not an
I still have reason for it. I still like having 911 feature tied to my
home address for one.
But a couple more practical reasons for still having a "land line" is
the lousy reception for cell phones around my house and the fact that
cell phones are still too "walkie-talkie" for my taste in most cases.
One person has to completely stop talking in order for the other to be
heard. I don't know if this is a digital transmission thing or what,
but with land lines and even the cable VOIP lines, you can still hear
what's on the other line when speaking.
That's very important for having a more natural discussion.
"Playing is not something I do at night, it's my function in life"
I thought the same thing as far as the sound quality. But suddenly
everyone I was talking to over the landline was using a cell phone, so
it became superfluous. My wife tells people (because she thinks its
funny), " ... he doesn't carry it anywhere, not even around the
house--he never even unplugs it!" Of course, that's not completely
true...but it's mostly true. I even answer it less and less frequently
(particularly, if I don't recognize the area code).
The lousy reception thing can be taken care of with a picocell.
Basically, you have your own cell station that connects to "Ma" over
the Internet. The "half-duplex" voice is certainly an issue with cell
phones. 911 for home shouldn't be an issue though. They should be
able to locate you, without any problems.
The cell phone issue that you didn't mention was disaster recovery.
Cell phones aren't of much use if the tower loses power and their
backup power isn't anything like the POTS COs of years gone by. OTOH,
in many disasters, the cell system was the only communications that
If you want it all, I guess belt and suspenders is the way to go,
though if you don't use things, they tend to not work when they're
Well, you're paying for a mobile phone. If you want it to work at
home, you may have to pay extra. ;-)
At least with Verizon, it's a one-time charge. They don't charge for
the Internet->POTS connection. I think AT&T does the same.
These have always struck me as one of the greatest
marketting feats ever: get people to use their own
internet bandwidth, that they pay for, to compensate
for inadequate service on the cell system that they're
also paying for. Viola! They get to pay twice for
