13. NV8500 Monitor Configuration and Operation
UniConfig Settings
To maximize efficiency, only one signal is sent from each input or output card to the monitor card
for forwarding to monitoring equipment. This means that only one signal from each input card or
output card is monitored at any give time.
Whether or not input and/or output monitor signals can be accessed and managed depends on the
application version currently loaded on the router’s control cards and if a Monitor Level has been
created using UniConfig. (See
UniConfig Settings on page 130.)
For instructions on making connections to the monitor backplanes, see the NVV8500 Family Rout-
ers User’s Guide.
UniConfig Settings
To access and control monitor signals, a Monitor Level needs to be created in UniConfig. Every
router has at least one control card. The version of the control application currently loaded on the
control card determines what monitor signals are accessed and how to configure a Monitor Level in
UniConfig. The level must be created separately for each control card in the router.
Each output monitor backplane has two outputs. These outputs in the NV8280/NV8280-Plus and
the NV8576/NV8576-Plus can function independently, but only when routed to separate output
cards (each card has 18 outputs), otherwise the monitor take is executed on both monitor outputs.
For example, when the Monitor Level is selected, performing a take of 2 to 1 followed by take 5 to
2 results in both monitors routed to output 5. In contrast, take 3 to 1 followed by 19 to 2 result in
monitors connected to different outputs (3 and 19 correspondingly).
Similarly, each input monitor backplane has two outputs. Specific to application version 14.0.0.xx,
in the NV8280/NV8280-Plus and the NV8576/NV8576-Plus these outputs only function indepen-
dently when they are routed to separate input cards. Each card has 9 inputs, so performing a take of
2 to 3 followed by take 5 to 4 results in both input monitors routed to output 5. However, take 3 to
3 followed by take 10 to 4 result in monitors connected to different outputs (3 and 10 correspond-
ingly).
NV8144 has two monitor outputs, one for monitoring router outputs and one for monitoring router
inputs. These two outputs are independent because they have connections to different sets of cards:
input and output respectively.
Mapping to the Monitor Level
In UniConfig, when creating the Monitor Level you enter the total number of monitor signals. Only
‘OUT’ connectors on the monitor backplanes are used to send signals to monitoring equipment.
Therefore, only these connectors are managed in UniConfig and configured as ‘Physical Outputs’
and ‘Controller Outputs’. How each ‘OUT’ connector maps to a Monitor Level output changes
depending on the router and number of connectors.
The NV8144 uses only one monitor card. This means that the ‘OUT 1’ is used to monitor all out-
puts and ‘OUT 2’ is used to monitor all inputs. ‘IN 1’ and ‘IN 2’ are unused because the NV8144 is
a standalone router. However, when configuring the Monitor Level in UniConfig, four connections
are configured. This is due to the design of the monitor card, which maps ‘OUT 1’ to output 1 and
maps ‘OUT 2’ to output 3.
