DV-33128
Recommended protected path ranges for DV-33128 routers are as fol-
lows:
For example, to protect an output in the range 1-32, choose a corre-
sponding input in the range 1-32; this will be the primary path. For the
secondary (failover) path, choose an output in the range 33-128 and a
corresponding input in the range 33-128.
This will provide the most independent possible paths through a DV-
33128, i.e., the primary path will use one pair of input and output
boards while the secondary path will use a different pair of boards.
CAUTION With a DV-33128, it isn’t possible to arrange completely independent
paths, i.e., paths that use different matrix boards and power supplies.
Protected path configuration for DV-33128 routers provides redundancy
for input and output boards only.
Note that for a DV-33128 router the maximum number of protected
paths is 64.
A more detailed example is shown in
. This table shows a
sequential 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.
