If it were limited to my house how would that be true? Especially in my
case where the carriers don't provide adequate signal strength into my
residence?
***** Moderator's Note *****
It's not a zero-sum game. The FCC is probably concerned that such a
device could become common enough that they would have trouble
enforcing the rules at a later date: I'd bet they feel it's better to
nip it in the bud.
Don't forget that bureaucracies have very long memories: the FCC is, no
doubt, harening back to the way the Citizens Band grew into a monster
that they can't control even today.

Putting on my mobile carrier hat, I would say that there is no way to
tell where someone might install one of these things, and it's clearly
being marketed as a way to bypass the carriers' network, not as a
signal booster.
I'm not a big fan of any of the mobile carriers, but this does not
impress me as a viable way to circumvent them. If the mobile carriers
weren't such doofuses, they would give you a free real femtocell if
you'd promise to keep service on your cell phone for some period, a
year or two.

Yes, of course. The company is owned by a CLEC which has numbers all
over the country, and they assign one as soon as you plug in your
device and it registers itself.

PS: A 20 second visit to magicjack.com would have answered this question

***** Moderator's Note *****
According to an article in the Winter 2009-2010 issue of "2600":
"While the underlying carrier (YMAX) is a CLEC, MagickJack is
specifically not offered as a CLEC product." The article says
MagickJack claims to be a "multimedia experience which includes a
voice over Internet information service feature. It is not a
telecommunications service, and is subject to different regulatory
treatment from telecommunications services". It's an open question as
to why MagicJack's owners take such pains to try and distance their
offering from FCC and local PUC regulation.
Also, according to 2600, the MagickJack software cannot be
uninstalled, even if a customer returns the MagickJack. The author
also rates MagickJack's voice quality "between poor and terrible", and
goes on to say that "In my market, MagicJack quality is so poor that
the service is virtually unusable". He also notes that "... when you
install the software, the End User License Agreement (EULA) has a few
nasty surprises", which includes the right to send the customer
commercial email messages, display ads on the computer, and supply
computer-usage details to Google.
Suffice to say, I'd be very careful about purchasing any MagickJack
offering, whether a femtocell unit or otherwise.

Not really. My presumption was being able to receive a call made to my
cell phone number. It appears call forwarding would have to be used to
make that work, which in this circumstance, would be a giant PITA.

Many telecom jobs have been shifted to non union positions. For
example, I don't believe people who work in the cellphone divisions
are unionized. I don't believe newcomer cellphone carriers or
landline carriers, or cable phone are unionized either. Many
functions for large businesses once performed by unionized telco
personnel are now done by non-union employees of the subscribers.
The union itself calls itself "CWA" now and for years has sought to
represent service workers in other industries.

While I'm a union support through and through, I'm hard-pressed to criticize
AT&T for this. People are simply not getting many landlines anymore. The
unions should have done as the longshoremen did when containization came to
be: negotiate other jobs so that their members would still have work. But
they didn't. Where was the CWA leadership?

It's not like I have much sympathy for the carriers. For one, the fact that
they charge 20 to 25 cents a message for text that takes miniscule bandwidth
is unconscionable.
And I'm against the selling of the spectrum that they pressured the FCC into
granting.

Can I throw my $0.50 (inflation, you know) thoughts into this?
Yes, it's [expletive deleted] annoying that they charge
this amount, but:
a: it's not a life saving necessity. People have the choice
whether to use this service or not.
b: the business world is filled with products where the marginal
cost of manufacture/distribution is just about negligible. Since
we're discussing telecom, just ask yourself how much it costs
a satellite tv company to add another subscriber?

Sounds much like a clone of the Verizon femtocell unit (officially known as
a "Verizon Wireless Network Extender") that people have been talking about
elsewhere in the newsgroup.
If Verizon can do it "legally" there is no reason someone else can not do
the same thing provided they don't step on someone else's patents, but then
again phone companies seem to hate competition from startup companies.
Especially if the competitors product actually works.
***** Moderator's Note *****
The problem is that it's NOT the same thing as a Verizon femtocell:
it is, as another reader pointed out, only a way to turn a cell phone
into a cordless phone. The Verizon offering gives customers access to
their regular cellphone features, such as voicemail, but the proposed
MagicJack product does not.

When I was a kid they told us that automation would "free" us from

I saw a TASI installation in the underground AT&T Long Lines building
in San Luis Obispo, CA in the 1970s. This was the mainland end of an
undersea coaxial cable to Hawaii. The cable had vacuum tube amplifiers
at the bottom of the ocean. TASI does seem to be a sort of analog
packet switching and may suffer from the "pipe is full" problems of
other packet switched or statistical multiplexed systems. I wonder how
much it increased the capacity of the cable and how much capacity they
had to hold in reserve to keep from cutting people off. I imagine a
max increase is 100%.

Harold,
TASI simply switches "circuits" when the call is idle in one direction
or the other. There is a set of circuits that are available in each
direction and the TASI terminal assigns each call to a circuit
depending on whether voice is detected. The absence of voice makes
the receiving terminal insert noise into the circuit to the customer
so there is no need to transmit any signal. In this fashion, more
than twice the number of circuits can be put on a multiplexed circuit.
In the old analog days, a group was not 12 circuits on undersea cable,
but 16 circuits (3 kHz bandwidth instead of 4 kHz) a few groups would
be assembled into a set for TASI. The circuit gain was well above
100%. Digital TASI uses T1 carrier and typically has a circuit gain
well above 100%. In the digital version, if a circuit needs
connectivity (i.e. speech is present) and there is no available time
slot, the link regresses to 7 bit encoding instead of 8 bit encoding
to allow the conversation to continue.
The controls for a TASI system are expensive, thus their use was
restricted to expensive circuits, e.g. undersea cable. Today there is
a real surplus of undersea fiber capacity, so these kinds of systems
are not as attractive as in previous times.
VOIP often uses the same kind of active circuit switching (albeit in
the packet domain...) and doesn't send packets when there is no voice.
BTW, voice detectors have an "attack time", so often the first part of
a syllable is clipped, reducing the quality of the connection. Modems
on TASI circuits resulted in a dedicated circuit, since modems had no
quiet time.

Yes and no, there is usually a configurable option on VoIP end devices to
keep sending packets on silence or not to save on bandwidth (Voice

That's not bad at all. If you consider that's 30 years worth of
deferred maintenance, that's only $2,000/year worth of maintenance for
the whole section of plant.
The thing about maintenance costs is that you can pay them now or you
can pay them later.

They still have not done a replacement, just a bunch of fixes. The
PUC is getting weekly updates from both AT&T and me. My DSL took a
dump again and I switched over to my Sprint MiFi and plan on having
them adjust my bills for the past 6 months by 1000%.
I was up in the mountains north of Sacramento and it looks like they
are about 3 months from U-verse there, that will be nice since all
they have is dialup unless you want to spend $200.00 plus $60 a month.

Yes. That's how they make their money. When they receive an
incoming LD phone call, they bill the LD carrier the usual
switched-access termination fee. When they place a call, they take
advantage of a regulatory ambiguity which states that VoIP-originated
calls might be exempt from paying.

The 100 mW rule is more urban legend than fact. The 100 mW power
limit for *intentional* radiators applies (or did apply) to the AM
broadcast band and 27 MHz CB. Other bands that allow unlicensed
intentional radiators have different power levels, often based on
field strength.
The current rule for AM broadcast is a field strength of 15 uV/m at
lambda/2pi from the radiator (this is used for carrier current),
though campus systems are only limited in strength at the edge of the
campus. CB is now 10 millivolts/meter at 3 meters. For FM, 250
microvolts/meter at 3 meters. For 216-960 MHz (old cellular), 200 uV/m at 3m.

Indeed, it's not clear to me that unlicensed intentional radiators
are really allowed on occupied cellular frequencies. If a cellco
authorizes or sells a femtocell, they'll have at least some
control. Borislow & co. are likely to face opposition from the
spectrum licensees, and I'm not confident that they'll win.

So, would it be accurate to say that a packet switched network could
have high quality voice transmissions (as good or better than existing
landlines) if they were properly engineered to do so?

Absolutely -- most telco voice transmissions today operate over a
packet-switched network, albeit with very small packets. With the
current state-of-the-art in high-speed network technologies (all
packet-based), the serialization delays that motivated the design of
so-called "cell-switched" networks like ATM -- the backbone of most
traditional telco networks -- are much smaller. An appropriate
queueing discipline combined with some sort of resource reservation in
the switches can provide sufficient quality-of-service for
high-definition video circuits, never mind the comparatively miniscule
bandwidth required by voice telephony.
Consider, for the moment, the case of someone using VoIP to make a
local call over naked DSL. Their VoIP terminal (i.e., phone) will
send RTP/UDP/IP packets over the home Ethernet LAN to the DSL modem.
The DSL modem then encapsulates these packets in ATM cells and sends
them to a DSLAM in a telephone central office. Those cells are then
forwarded by the DSLAM over permanent virtual circuits on a carrier
ATM network (possibly even the ILEC's network) to the ISP's POP --
probably located in or next to another CO in a nearby major city --
where a router (probably made by Cisco) accepts the ATM cells and
reassembles them into IP packets, delivering them to the VoIP gateway
(possibly in the same Cisco box) which extracts the digitized
audio,[1] possibly transcodes it, and probably converts it back into
ATM cells again (this time labeled "voice" rather than "data") for
carriage on the ILEC network to the terminating CO switch. The only
reason for the ISP to use ATM between the DSLAM and their POP is the
fact that ATM is readily available in nearly every ILEC CO in their
service area, whereas dark fiber isn't.

audio stream from the UDP/IP packets it receives.
