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 Ether-
net to unframed T3.
T1 and E1 un ts feature
two techn ques of l ne

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
unfra ed operation, so you can
take advantage of T1’s 1.544-Mbps
speed in a single channel. Data
trans ission is synchronous and
full duplex.
T1 trans ission uses two
techniques of line coding, either
B8ZS or AMI. Line i pedance is
rated at 100 oh s across the T1
channel.
Clocking can be received fro
the T1 line, anaged externally
fro the network device connect-
ed on the other end of the V.35 or
RS-530 link, or perfor ed internal-
ly fro the converter’s oscillator.
For diagnostics, local analog
loopbacks can be activated fro
the T1 or DTE interfaces. Three
front-panel LEDs show when data
is trans itted to the link, when

data is received fro the link, and
when no data is received fro the
link. A fourth LED indicates active
loopback. A fifth LED shows when
the unit is powered up.
Three odels each are avail-
able for T1 to V.35 conversion and
T1 to RS-530 conversion. Choose
fro AC- or DC-powered stand-
alone units or Rack ount Cards.
The Rack ount Cards fit in our
RackNest 2/14 (Product Data
Sheet 19273).
Bring V.35 and E1 together.
The E1 Rate Converter is very
si ilar to our T1 Rate Converters,
but with two notable differences.
First, it e ploys HDB3 or AMI
line coding for E1 trans ission.
Second, line i pedance is rated
at 120 oh s (balanced) and 75
oh s (unbalanced) across the E1
channel.
Conversion is between V.35
and 2.048-Mbps E1 only. Choose
fro two odels, depending on
your application’s power.
aking what’s fast even faster.
If you want to take interface
conversion to extre e speeds,
this Rate Converter can connect
your 10-Mbps Ethernet or 100-
Mbps Fast Ethernet equip ent to
a single-channel 44.746-Mbps
T3 service!
A built-in Ethernet bridge with
VLAN support enables virtual LAN
connections. The Rate Converter
perfor s fra e filtering and
forwarding at the rate of 150,000
fra es per second, and the
bridge causes no LAN delays.
The T3 Rate Converter provides
full control over ulticast and
broadcast essages. Autonegoti-
ation enables a plug-and-play
Ethernet connection without any
additional configuration.
Front- and back-panel LEDs
indicate Alar Indication Signal
(AIS) and Loss of Signal (LOS) line
conditions and provide infor ation
and status of the Ethernet/Fast
Ethernet link. Clocking either can
be received fro the T3 line or
done internally by the converter’s
oscillator.

Recognize any of these
situations?
• You wait ore than 30
inutes 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 nu ber and the tech
refuses to help you.
• It’s 9 p. . and you need help,
but your vendor’s tech
support line is closed.
According to a survey by Data
Co unications agazine, 90%
of network anagers surveyed
say that getting the technical
support they need is extre ely
i portant when choosing a
vendor. But even though network
anagers pay anywhere fro 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 co ponent
for your application.
