Protected Paths
The maximum number of Protected paths for a TRX-NXT-128x128 router is
64.
A more detailed example is shown in Table 11. This table shows a sequen-
tial wiring scheme for a system yet to be installed or a system where cables
will be re-arranged in a symmetrical pattern in order to simplify Protected
path operation.
The numbers shown here correspond to the connector numbers used
during router configuration (but not, in most cases, to the actual silk screen
number on the rear panel itself since the silk screen numbers only run from
1” to 32.”)
In Jupiter-controlled systems, the Name column in these tables corre-
sponds to the logical input/output name”; the entries in the number
column will correspond to the physical” input/output number.
The next example applies to existing systems where re-arrangement of
cables in a sequential pattern is not practical or desirable:
Notice that I/O numbers conform to the ranges that are shown in Table 10
Recommended Protected Path Ranges on page 102.
