Because the rack‘s front panel is hinged, you can add and
remove cards from the front of the unit without disturbing
the DTE and line connections at the rear of the rack.
The front panel is also translucent, so you can easily view
the LEDs on the front of the cards. To access a card’s test push
button to perform loopbacks, just lower the front panel.
When you order a modem, you’ll receive the Standalone
or Rackmount Card 9600 FP Modem, a leased-line cable, and
a user‘s guide. The MD1980A-DC also includes a shielded DC
power cable.

According to a survey by Data Communications
magazine, 90% of network managers surveyed say
that getting the technical support they need is extremely
important when choosing a vendor. But even though
network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support
contract, the technical support and service they receive
falls far short of their expectations—and certainly isn’t
worth what they paid.
At Black Box, we guarantee the best value and the
best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just
the right component for your application.
