Duplication and Expansion
As described in the Planning section of this manual (starting on
page 43 ), Trinix routers are designed to duplicate/expand inputs and
outputs using passive splitter/combiner expansion panels. Whenever
an expansion panel is connected, signal gain must be increased to com-
pensate for the added circuitry.
In addition, unused connectors should be terminated for optimum per-
formance.
Note For Jupiter-controlled (0-based) systems, the input/output numbers in
the following discussion should be decreased by one (1). For example,
block 1-256 should be understood as block 0-255, etc.
Note
Frame numbers are determined by the input/output blocks served by the
particular frame. E.g., for a DV-33256 router, input block 1-256 and
output block 1-256 must be connected to frame zero. For more informa-
tion about frame numbering, see
page 146 .
Note
Unused connectors should be terminated for optimum performance.
Output Duplication
Output duplication (dual/quad outputs) requires output splitters and
output gain increase.
Full chassis output duplication
In this arrangement all outputs from a given chassis are duplicated and
must therefore be boosted. See Figure 61 for an example.
Figure 61.
The necessary gain increase is accomplished by
• Closing the rear-panel Input Expand DIP switch (for the location of
this switch, see page 98 [128 x 128]; page 100 [256 x 256]; or page 102
[512 x 512]), and
• Setting the output board jumpers (or DIP switches) to the “Expand
Enable” position (as shown on page 128 and page 129 ).
