Data Router Constraints
There are several required constraints when dealing with data routers and
path finding:
• The software on AccuSwitch will only support the Venus DM-400B and
the Concerto Data Routers.
• Data routers that are part of a path must be connected to the CM-4000/
44000 controllers defined as “AS” (AccuSwitch) in the Type column of
the Network Description table.
• The physical I/O numbers must be defined in both the input and
output tables because the data routers require a switch to be made in
both directions (for the forward and return data).
• A “SAFE” input for the data router level must be defined. This input is
used with the “Enforce” or “Advise” features.
• The maximum number of “hops” in a data router path finding path is
2. For example, one Venus could be connected to a Concerto, which in
turn could be connected to a second Concerto.
AccuSwitch also has the ability to lock or protect a data router output. This
feature will also lock the reverse output which protects or locks the data
path in both directions.
