Save money, workspace,
and time by centralizing your
data-communications
equipment.
LED status indicators for
each card show error
connection, connect rate,
and connection speed.
Cards support data rates
up to 33.6 kbps over dial-up
lines and 2- or 4-wire leased
lines (depending on model).
Modem Rack features a
redundant power-supply
option.
All are hot-swappable for
easy installation, removal, or
replacement.
T
he Modem Rack houses
up to 16 modem cards and
one power supply in one
centralized location.
The rack conveniently
mounts in any industrystandard 19-inch equipment
rack. Along with valuable
work space, it saves you the
expense of installing extra
modems or cables. You can
mount the rack in the same
cabinet as your computer, or it
can be enclosed in a separate
cabinet of its own.
Specifically designed for
V.34 modems, the rack
provides the RS-232 serial,
phone line, and power
connections (located at the
rear of the unit) for modem
cards via a backplane
interface. The cards slide into
the rack and seat into their
own backplane connector The
modem’s gold edge connector
is offset so that the modem
cannot be incorrectly inserted.
The rack’s data-port
connectors are DB25 female
connectors, which can be used
for async or sync RS-232C/D

Key Features
Modem Rack, V.34 Modem Card,
and
Redundant Power Supply
data transfer to a modem card.
The rack also features an RJ-11
connector for each modem.
A front panel labels the
LEDs on each card so that the
connect rate, error correction,
speed, ring indicator, and
other call status indicators can
be monitored.
There’s also room for a
redundant power supply (used
to keep the system going even
if the first power supply fails).
Not Just Any Card
You get everything you
expect from an enhanced V.34
(33.6-kbps) modem. For
example, it automatically
adjusts to line conditions and
the capabilities of the modem
on the receiving end.
You not only get the
highest possible speed with
the modem card, but the most
accurate error correction and
most efficient data
compression possible for each
connection. For instance, when
the modem encounters noisy
line conditions, it
automatically falls back to a
slower speed. When line
conditions improve, its speed
accelerates.
But more than that, it also
includes additional support for
dial backup and leased lines.
Order the MD1600C for 2- and
4-wire leased-line applications,
and the MD1601C for use over
2-wire lines.
With convenient DIPswitch settings, it’s easy to
configure the modem for
optimal performance with
AS/400.
The card supports Group 3
(V.29 for 9600/4800 bps) and
V.17 (14.4-kbps) fax, and both
sync and async equipment.
What’s more, it can be
configured for a point-to-point
network installation.
The card can also store up
to 30 call-back numbers.
You also get flash memory
for data pump and controller
firmware updates, and UUCP
spoofing for streamlined batch
transfer throughputs.

Technically Speaking
T
he rack modems are
generally used in a
central-site computer
environment, connected to a
mini- or mainframe computer.
In these installations, the main
purpose of the modem is to
automatically answer
incoming calls from remote
users.
After seating the modem
card into one of the 16 slots on
the rack, you simply connect
an RS-232C cable to the DB25
female connector on the
backplane of the rack. You can
also connect your phone line
directly to an RJ-11 connector
on the rack’s backplane.
The card also features:
• ITU-T V.42 LAP-M and
MNP Classes 3 and 4 error
correction;
• Automatic disabling of
compression when
transferring files that are
already compressed;
• Serial-port data rates
adjustable to 115.2 kbps;
• Autodial, redial, pulse
(rotary), and Touch-Tone
dial;
• Compatibility with the
standard AT command set
used by most
communication programs.
• On-screen help menus;
• Nonvolatile memory for
storing customized modem
parameters and 10 phone
numbers;
• Ability to respond to EIA
TR.29 Class 2 fax
commands;
• Support for Unix
®
to Unix
UUCP Spoofing;
• Support for IBM
®
AS/400
™
and System 3x
environments.
You also get an array of
circuit board controls via the
modem card’s 16 DIP
switches. You can use the
switches to configure options
or set default values in the
command mode. For instance,
you can position the switches
to echo modem responses, set
the modem to operate at the
highest efficiency level, select
transmit clock source, and
enable and disable various
modes.
Or you can simply rely on
the factory-default settings.
They’re based on the
assumption that you’ll use the
modem card to dial up a
remote installation where a
call is automatically answered.
Most communicationssoftware packages have
installation procedures of their
own, and your package may
call for certain modem DIPswitch settings.
