T1 Rate Converters
enable you to convert
from V.35 or RS-530
to T1.

E1 Rate Converter
enables you to convert
from V.35 to E1.

T3 Rate Converter
enables you to convert
Ethernet or Fast Ether­net to unframed T3.

T1 and E1 units feature
two techniques of line
coding each and three
methods of clocking.

T3 unit includes a built­in Ethernet bridge.

AC- and DC-powered
models available, plus
Rackmount Cards.

onvert between T1 and V.35 or

RS-530, E1 between V.35, and
T3 between Ethernet and Fast
Ethernet with our Rate Converters.

Two ways to T1 speed.

T1 Rate Converters support
unframed operation, so you can
take advantage of T1’s 1.544-Mbps
speed in a single channel. Data
transmission is synchronous and
full duplex.

T1 transmission uses two
techniques of line coding, either
B8ZS or AMI. Line impedance is
rated at 100 ohms across the T1
channel.

Clocking can be received from
the T1 line, managed externally
from the network device connect­ed on the other end of the V.35 or
RS-530 link, or performed internal­ly from the converter’s oscillator.

For diagnostics, local analog
loopbacks can be activated from
the T1 or DTE interfaces. Three
front-panel LEDs show when data
is transmitted to the link, when

data is received from the link, and
when no data is received from the
link. A fourth LED indicates active
loopback. A fifth LED shows when
the unit is powered up.

Three models each are avail­able for T1 to V.35 conversion and
T1 to RS-530 conversion. Choose
from AC- or DC-powered stand­alone units or Rackmount Cards.
The Rackmount Cards fit in our
RackNest 2/14 (Product Data

Sheet 19273).

Bring V.35 and E1 together.

The E1 Rate Converter is very
similar to our T1 Rate Converters,
but with two notable differences.

First, it employs HDB3 or AMI
line coding for E1 transmission.
Second, line impedance is rated
at 120 ohms (balanced) and 75
ohms (unbalanced) across the E1
channel.

Conversion is between V.35
and 2.048-Mbps E1 only. Choose
from two models, depending on
your application’s power.

Making what’s fast even faster.

If you want to take interface
conversion to extreme speeds,
this Rate Converter can connect
your 10-Mbps Ethernet or 100­Mbps Fast Ethernet equipment to
a single-channel 44.746-Mbps
T3 service!

A built-in Ethernet bridge with
VLAN support enables virtual LAN
connections. The Rate Converter
performs frame filtering and
forwarding at the rate of 150,000
frames per second, and the
bridge causes no LAN delays.

The T3 Rate Converter provides
full control over multicast and
broadcast messages. Autonegoti­ation enables a plug-and-play
Ethernet connection without any
additional configuration.

Front- and back-panel LEDs
indicate Alarm Indication Signal
(AIS) and Loss of Signal (LOS) line
conditions and provide information
and status of the Ethernet/Fast
Ethernet link. Clocking either can
be received from the T3 line or
done internally by the converter’s
oscillator.

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 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.

Don’t waste time and
money— call Black Box today.
