ability of individual parts, enhance air movement throughout the
chassis, and identify potential system problems in time to take preven-
tive measures.
Trinix also offers Broadlinx technology, which aids serviceability by
providing status displays and monitoring functions through a network
connection.
All circuit boards contain some common circuitry for hot swapping, cir-
cuitry for DC to DC conversion, and a micro-controller as part of the
Broadlinx technology.
Hot swap circuitry is used to simplify field servicing and upgrades.
The DC to DC conversion is necessary because the chassis design dis-
tributes one voltage, 48 volts, to all cards leaving the responsibility to
each card to convert down to the needed voltage level.
Each board has a micro-controller that is part of an overall communica-
tions bus which is part of the hardware for the Broadlinx technology.
This hardware is what gathers all of the particular board information
(voltages, signal presence, reclocking settings, etc.) as well as enables
the firmware updates via network connection.
For “protected path” operation, the Broadlinx software can be config-
ured to monitor router outputs that are feeding critical downstream
equipment (such as a transmitter). If the “primary” output signal is
interrupted, the system will automatically select the “secondary”
output that is carrying the same signal and trigger a system alarm. Pro-
tected path operation is available for single-chassis (non-expanded)
systems only, with the exception of multi-chassis DV-33512 routers
with expanded inputs. Protected path operation also requires HO-
33120 HD/SD Output Boards in the paths to be protected. For more
information, see

The Broadlinx option, which consists of Broadlinx software running on
the NR-33000 Sync/NIC/OPM board, allows SMS 7000 or Encore
control using Grass Valley CPL (Control Point Language) through an
Ethernet connection.
Broadlinx also provides web pages for the following operations:
• Network configuration of the NR-33000 board(s)
• Downloading of software upgrades to the various boards in the
system
• System monitoring using Internet Explorer
