A Pedigree of Reliability
The original Trinix platform is the world’s
most popular broadcast routing switcher,
with more than sixty million crosspoints
continuously in service. For you, this
means a pedigree of reliability that you
can point to rather than simply hope for.
All Trinix routing switcher customers
can upgrade to 3 Gb/s, no matter when
they purchased their routing switcher.
This illustrates the long-term support
and forward-thinking design of the Trinix
platform. You can rely on the Trinix NXT
routing switcher to keep working, but
you can also trust the support you will
receive now and into the future.
CleanFlow Superior Design
The CleanFlow architecture is the key to
the performance and intrinsic reliability
of the Trinix NXT routing switcher. This
architecture reduces the number of
separate circuit cards which, in turn,
shrinks the number of local power
supply circuits, interconnections, and
distributed control circuits. With fewer
repeated circuits, the Trinix NXT routing
switcher has an industry-leading low-
power consumption, which reduces
operating costs as well as operating
temperatures and air-conditioning
expenses. However, the key benefit of
the platform is its comprehensive signal
handling. Fewer circuits mean more
straightforward signal paths and more
room on boards for optimized layouts.
Special circuit board substrate materials,
the use of the latest generation of 3 Gb/s
circuits, and other design techniques
enhance the ability of these boards to
ensure the cleanest possible signal flow.
The result is signals that are preserved
better in the Trinix NXT routing switcher,
meaning signals at their limits are more
likely to be recovered—and that you
will spend less time troubleshooting,
redesigning and reinstalling circuits,
and adding workarounds to solve signal
issues.
Better Cooling
As part of the CleanFlow architecture,
the Trinix NXT routing switcher uses a
common plenum chamber and airflow for
the entire chassis—all its cooling power
is applied to all the circuits. The platform
also uses blowers rather than fans to
improve cooling efficiency. Arranged in
an N+1 configuration, the blowers also
greatly ease servicing.
As a result, the airflow of the routing
switcher follows naturally from bottom
to top, which suits air conditioning
installations as they are designed
to handle hotter air higher up. The
architecture exhausts through a single
vent, which, unlike other designs, can
easily be kept unobstructed when the
router is cabled.
By reducing its cards and connectors,
the routing switcher increases its
internal airspace. This airspace, along
with its low-power circuitry, this makes
the Trinix NXT platform much easier
to cool. For this reason, the routing
switcher is more resistant to hot-
spots which can both degrade signal
performance and cause early failure.
Better cooling therefore makes for better
circuit operation and higher reliability.
Advanced Protection
With large routing switchers, more
than any other piece of infrastructure,
reliability is critical. That is why many
users specify redundancy as part of
their system designs. The Trinix NXT
routing switcher supports three types
of redundancy, which allows a system
architect unprecedented flexibility. Two
of these schemes are unique in that
they provide protection while increasing
reliability.
Redundant Matrix Protection
The core of any routing switcher is
its central matrix circuit. For smaller
installations, protecting this key
component can be important. The Trinix
NXT platform offers a redundant matrix
solution on some models to protect this
vital circuit. This is the platform’s basic
level of redundancy.
Protected Paths
Protected paths works by providing two
completely redundant paths through the
routing switcher. These include the input,
matrix, and output circuits. As a result,
all of those circuits, the whole path in
fact, are protected.
Protected paths allow a system architect
to assign protection for only the key
inputs and outputs—a targeted and
highly effective approach.
The reliability limitation of most
redundancy solutions is that they use an
active, and therefore failure-prone, circuit
to implement the change over from main
to spare. Protected paths use passive
path selection to change over. For this

Protected Path Redundancy
TRiNiX NXT REdUNdANcY OpTiONS
The fully protected paths option of the Trinix NXT platform protects all circuit paths in the router—all the way back to redundant sources if you
use them (see below). A failure in any circuit board or in the signal-source chain triggers an automatic failover. As the most cost-effective way to
protect your most important signal paths, this option uses the Trinix NXT system’s passive port expander tools—the same splitting and combining
circuits used in expanded systems. These tools offer maximum reliability at no added power cost and can be implemented in single- or dual-router
configurations.
