Key Features

PHONECOUPLERII

The coupler’s easy to install,
too. Simply plug it into your
computer’s modem jack labeled
“LINE,” and strap the two units
together tightly.

If you’re connecting to an
AT&T Merlin phone system,
which uses a handset with a
chisel-shaped mouthpiece, use
the included round rubber
adapter.

But if you need to fit a square
handset to the round coupler,
order an optional Acoustic
Coupler Handset Adapter
(MD001). It includes an adapter
for the mouthpiece and an
adapter for the earpiece.

For PC card or PCMCIA
modems that require more
current from the Phone Coupler II,
just set the coupler’s internal
”high-current” switch inside the
battery compartment.

Although the Phone Coupler II
can dial automatically, in some
cases you’ll need to dial manually.
Cellular telephones and some
pay, rotary-dial, international, and
digital or PBX telephones will not
accept the dialing tones produced
by your modem. Just look for a
manual-dialing feature in your
communications software.

Recognize any of 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 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.
