FAQ. What is VividNET's approach to the 56K ITU modem connection standards.
Communication went 56K X2 standard for most of its POP to the East of 605 FWY, it is
currently waiting for the ITU standard to take place and fully upgrade to 56K connection
for all its POPs.
What is a Standard?
(Original information from 3COM
web site )
A standard is a technology agreed upon by different vendors
in a specific industry. New standards are driven by market trends, technological
advancements, and consumer demand. Modem standards begin as proprietary technologies
submitted by individual vendors to the International Telecommunications Union (ITU), a
formal worldwide telecommunications standards body whose charter organization is the
United Nations. The ITU may adopt a proprietary protocol from an individual vendor. Or it
may adopt a standard based on technologies from different vendors.
Standards are initially "determined," then later
ratified or "decided." A determined standard is based on a technical agreement
between active union participants. Once determined, the core technology of a standard
won't change. Modem vendors develop and ship products based on determined standards.
Determined standards are later agreed upon by all members of the UN and considered
ratified. In the unlikely event modifications are made to the V.90 56K standard between
determination and ratification, 3Com's Flash DSP and Flash ROM capabilities will deliver
enhancements with simple software downloads from our Web site or BBS.
3Com fully supports the determined V.90 standard and cast a
favorable vote for the technology comprising it. 3Com will quickly develop upgrades for
existing x2 technology products and develop new V.90 56K standard products. Users
will enjoy universal compatibility with all products that are either upgraded or designed
with the new V.90 56K standard, as well as all products with x2 technology. And, 3Com is
leading interoperability testing with other vendors including Lucent Technologies to
insure optimum compatibility.
What does the V.90 56K ITU standard mean?
The ITU (International Telecommunications Union) is a
committee of the United Nations. Its job is to make sure all telecommunications devices
(like telephones, fax machines, modems and so on) can "talk to" each other, no
matter what company makes them or in what country they're used.
As engineers think up new ways of connecting, the ITU meets
to review these technologies. Different companies may present slightly different protocols
(plans) for achieving the same result -- U.S. Robotics®
x2 technology and Rockwell K56flex technology, for example. The ITU works out
compromises between these protocols, to reach a single, worldwide standard. Once that
standard has been determined, all companies can start building products that comply with
How does it affect you?
3Com (then U.S. Robotics) brought the first 56K modems
to the market, using x2 technology. As a proprietary (non-standard) protocol, x2
technology required x2-capable equipment at both ends of the connection: ISPs (Internet
service providers) or corporate networks on one end, and modem users on the other. And
because K56 flex was also a proprietary protocol, it required K56 flex capable equipment
on both ends. Modems with one technology could not get high speed downloads from providers
with the other.
Now that the ITU standard has been determined, providers and
modem users with standard-compliant products will be able to connect at high speeds no
matter who made those products. This means you can choose your Internet service provider
more freely. You'll get faster, more dependable connections to the Internet or your
corporate network. And because all the world's modem engineers are working with the same
technology, improvements will come faster, improving your online experience even more.
If you now use an x2 modem, you'll soon be able to upgrade to
the V.90 56K ITU standard, free, with a simple download from this Web site. (Some 33.6
modems upgraded to x2 technology may require hardware upgrades -- the Upgrade Advisor will
tell you which upgrade you need.) After you've upgraded, your modem will be compatible
with both the new standard and x2 technology. So you'll be able to get fast downloads from
any x2 capable ISP or corporate network, before and after they upgrade their equipment to
the standard. In other word, you'll also be able to get those same fast downloads from any
V.90 ITU standard-compliant provider, no matter who made their equipment.
