Duplication and Expansion
Duplication and Expansion
Trinix router’s inputs and outputs are designed to duplicated or expanded
using passive splitter/combiner expansion panels. Unused connectors
should be terminated for optimum performance.
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.
Frame numbers are determined by the input/output blocks served by the
particular frame. For example, for a TRX-NXT-256x256 router, inputs 1-256
and outputs 1-256 must be connected to frame zero. For more information
about frame numbering, see Frame Number Settings
on page 212 .
Output Duplication - Dual
The PE-33016 and PE2X2-3G Port expanders are passive, transformer-
based modules that can be used to provide two copies of the same signal.
The PE-33016 should be used for SD and HD signals. The PE2x2-3G pro-
vides the necessary bandwidth for 3Gp/s operations. The PE2x2-3G can
also be used for SD and HD operation. Functionality of the expander is bi-
directional and depends on connections only; no configuration is required.
Figure 29 and Figure 30 show a splitting application. In the figures below,
the PE33016 Port expander is used for an example only. Use the PE33016
Port expander for HD operations and the PE2x2-3G Port expander for
3Gp/s operations. Unused connectors should be terminated for optimum
performance.
