Less Wires, Please
I recently installed an SDSL line into my residence. Unfortunately, since
my SDSL is a baseband signal, we had to unplug my analog phone in order to turn it on. I
would rather not pay to have another set of wires run into my apartment. Do you know if a
device/service exists that would allow me to use a telephone over my DSL line (IP
network)? I am looking for something which could place and receive calls to/from standard
POTS essentially to completely replace a home phone. Thanks for any info you may
have.

One way is to get a PC equipped with an inexpensive Quicknet or ACS Innovations
Internet telephony card, and connect a phone to the card. Using Net2Phone or other service
providers will do the trick. Cisco/Selsius has a phone that will plug into an Ethernet
port (sans PC) but you will need a service provider that supports it.
CTI magazine associate editor Chris Donner:
I think this is pretty easily answered by a CPE device, such as FlowPoints
2200V, which provides four analog ports for fax/phone/modem connection as well as data
access via SDSL, an internal LAN, and support for a firewall, etc. For more information,
visit FlowPoints Web site.
Robert Hashemians September 1999 Reality Check column (Those Crazy Routers And
Switches. Their Prices Are Insane!) sparked a great number of comments from our
readers. We have included some of the comments below.
To the Editors,
I strenuously disagree with the conclusions you draw in your September 1999
column, Those
Crazy Routers And Switches. Their Prices Are Insane.
You state, that there is a conspiracy going on in the world of routers and
switches, and the goal is to squeeze every cent out of the consumer.
This statement is irresponsible and incorrect. Customers choose to buy Cisco products
for a variety of concrete reasons. Customers buy our gear not only because of the hardware
itself but also for the support, service, and trust in the Cisco name. That buying
preference has led us to number one market positions in a variety of markets. A huge gulf
separates customers expressing brand preference and a company acting as a monopoly.
For proof, look at buying and support processes. As with all computer gear, the initial
cost is a mere fraction of the total management and maintenance costs over the life of
that equipment. Cisco helps customers reduce those ongoing costs in a variety of ways: The
ability to configure and order products on our award-winning Cisco Connection Online Web
site, a superior support structure built into CO, and a wide number of Cisco Certified
Internetwork Experts qualified to design with and operate our equipment.
In the enterprise and consumer networking markets, Cisco faces cut-rate, but again,
customers choose Cisco because we provide high-quality hardware, software, and services.
You make this point yourself quite eloquently: After all, when I want to get
connected, I ask for a Cisco box too
They are like tanks. Once configured, they
continue working through thick and thin. Power outages, network topology changes, and
network operating system changes seem to have no effect on them. They dont crash,
and dont take forever to boot up
Like the Energizer bunny, they keep going and
going.
You also assert that prices have stayed high while products have not advanced. Neither
of these statements is true. In your analysis of the 2501 router, you claim the product is
fundamentally still a router, yet you admit that the devices features are more
advanced, supports more protocols, and is more optimized. You could also add that
todays router provides easier management and higher port densities than its
predecessors did. In fact, the theory of Moores Law is completely applicable in the
networking industry. Over a five-year period (19921997), for example, the price of
Ciscos 7000 router line dropped significantly, while port densities on the product
family increased to yield a 16-fold boost in performance. As a result, over that five-year
period, Ciscos price/performance ratio outpaced Moores Law by almost 25
percent.
Providing solid technology, good customer service, and support are all key to
Ciscos successes, and those factors are also reflected in the pricing of our
products. Customers evidently believe those prices are fair, since theyve made us
number one.
Sincerely,

Robert Hashemian responds:
One of the greatest assets of Internet Telephony magazine is the freedom it
gives its columnists to express their opinions uncensored. This column was a good example.
I respect the feedback I received and reiterate that I am a believer in Cisco quality. I
also believe that there is a premium to be paid for good quality. But I dont believe
that my assertion of the Cisco routers high prices was unfounded or unreasonable.
Perhaps the usage of word conspiracy was a bit exaggerated. It was meant
colloquially and certainly not literally.
I read your article in Internet Telephony Online Magazine, and I wonder if you could
help me out. I am doing a market survey of router performance as my master thesis. I have
tried to contact the vendors regarding obtaining some information about parameters that
they should give you when they advertise how good their product is; it has so much
horsepower (packets per seconds) etc... Though what they dont want to
tell you are the critical factors about their router.
The jitter, latency and packet loss are very important for VoIP but are the vendors
willing to provide these values? The answer is NO! Therefore I wonder if you have some
ways of obtaining these parameters. I have hit a brick wall trying to get this kind of
info for six weeks now. If I wanted to buy a car and met with the same attitude when
asking about the cars technical details, I would tell the dealer and the car maker
to get stuffed and turn to another dealer and car make. But, obviously in the world of
computers, it is the vendors who are calling the shots.
I would be very grateful if you could help me out in getting data on jitter, latency,
and packet loss for the following routers:
ACC (Tigris 3 slot, Amazon, Colorado); Cisco (2610, 3640); Nortel/Bay (ASN, ARN); 3Com
(NetBuilder II, SuperStack II 5xx).
Thank you for a great article and I look forward to hearing from you.

Editors note: Im tossing this one out to the vendors. If any
vendors care to respond, please send e-mail to ggalitzine@tmcnet.com.
In your well-written Reality Check
(September 1999), you asked whether folks had another theory why router and
switch prices dont drop. Actually, the clues to TWO fairly simple ones are
within your piece:
- Theyre tough. You mentioned how cheap scanners have become, and youre right;
but cheap means just that cheap. Todays $90-or-less scanner
doesnt begin to have the rugged build of the older higher-priced ones. Its
like comparing a heavy 1950s-model telephone, which youd practically have to
sledgehammer to kill, to a flimsy $9.95 telephone of today. As you said, Cisco routers
are like tanks. Building-in that sort of reliability just isnt cheap and
probably never will be.
- Theyre not (and never will be) mass-produced, at least not the way consumer
products are. Yes, Cisco makes many of its products, but compare the quantity with, again,
the scanners or video games you mentioned. Obviously, the more you make of any product,
the less each ones retail price needs to be in order to amortize the companys
initial investment. And this characteristic, too, probably wont ever change: There
are billions of consumers, but there almost surely never will be more than many thousands
of routers and switches.
