Note

The following discussion is based on a “1-based” numbering scheme. If
you are using a “zero-based” numbering system, subtract “1” from all
instances of input/output numbers.

DV-33512

The recommended protected path ranges for DV-33512 routers are as

follows:

For example, to protect an output in the range 1-128, choose a corre-

sponding input in the range 1-128; this will be the primary path. For the

secondary (failover) path, choose an output in the range 257-384 and a

corresponding input in the range 257-384.
Alternatively, the high-range of connectors can be used for the primary

path and the low range for the secondary path, as shown in

Table 3

Using either of these schemes will provide the most independent pos-

sible paths through a DV-33512, i.e., the primary path will use one set

of input, matrix, and output boards connected to one power source

while the secondary path will use a different set of boards connected to

a different power source.

Note that for a DV-33512 router the maximum number of protected

paths is 256.
