GLOBAL56KMODEM
Secure business communication.
If you have a business, then
you need security for your data
communications. You can count
on the Global 56K Modem to get
the job done.
This modem incorporates
the latest protective measures,
including dialback security,
password protection, and dial-
out restrictions. What’s more, the
Global 56K Modem includes 64-bit
DE encryption that’s specific to
the country of operation. This
form of encryption features super-
secure enhanced key
management. If you want
maximum security, you got it!
Deployable in any environment.
No matter if you have an
async or sync environment with
2-wire half-duplex or 4-wire full-
duplex communications, the
Global 56K Modem fulfills those
requirements.
Use this modem for both
leased-line and dialup P TN
operation. And judging by its
name, this modem is ready for
use in any country.
Built for now and the future.
The Global 56K Modem is
future-proof, too. It comes with
a built-in Flash ROM, so you can
download the latest standards
from the Black Box FTP site.
That way, you can keep this
investment up to date within
the V.90 standard.
The extras that make
the difference.
MNP®10 enables this modem
to handle increased speeds on
cellular circuits. Plus it comes
with digital PABX line surge
protection to keep data safe.
Lastly, it can be configured and
accessed remotely, saving you
from a road trip at odd hours.

Recognize these situations?
• You wait more than 30
minutes to get through to
a vendor’s tech support.
• The so-called “tech” can’t
help you or gives you the
wrong answer.
• You don’t have a purchase
order number and the tech
refuses to help you.
• It’s 9 p.m. and you need help,
but your vendor’s tech
support line is closed.
According to a survey by Data
Communications magazine, 90%
of network managers surveyed
say that getting the tech support
they need is extremely important
when choosing a vendor. But
even though network managers
pay 10 to 20% of their overall
purchase price for a basic service
and support contract, what they
get falls short of expectations—
and isn’t worth what they paid.
At Black Box, we guarantee
the best value and support. You
can even consult our experts
before you buy if you need help
selecting the right component for
your application.

I
n December 1997, a subset of
the International Telecommuni-
cations Union (ITU) voted in favor
of a compromise that ended
several months of debate
between the major players in
the 56K modem debate—U. .
Robotics®, Motorola®, Rockwell,
and others.
The compromise resulted in
the development of the V.90
Pulse-Code Modulation (PCM)
standard that was passed by
the ITU in February 1998. This
standard incorporates technolo-
gies from several companies.
PCM codes, which are already
used in the digital portion of the
telephone network, are the
cornerstone of 56-kbps modems.
Although the V.90 standard
was officially ratified in eptem-
ber 1998, many vendors intro-
duced V.90 products or hybrid
products compatible with propri-
etary x2™ or K56flex™ technol-
ogies before then. In many cases,
the migration from those K56flex
or x2 products to a V.90 product
was just a software upgrade.
The V.90 standard enables a
broader range of customers to
take advantage of 56K speeds
without compatibility problems.
TechnicallySpeaking
A
nalog modems transmit data
over ordinary phone lines.
Data transmitted across analog
lines is represented by a
continuously varying electrical
signal.
ISDN modems transmit over
digital lines running at 64 kbps.
Data is transmitted over either
one or two 64-kbps voice/data
channels and is encoded as
either a binary 1 (one) or 0 (zero).
When there are I DN modems
on each end of the line, they are
known as terminal adapters.
Terminal adapters enable
data to be transmitted or
received over I DN at speeds
up to 128 kbps. Terminal adapters
also enable you to connect non-
I DN equipment such as phones
or PCs to I DN.
