9 Switching Optical Routes
Route
The [Route A <->] field describes the route between port A and another
numbered port within the Optical Switch module.
If present, the [Route B <->] field describes the route between port B and
another numbered port within the Optical Switch module.
In Figure 145 on page -241:
•The [Route A <->] field shows that, within the Optical Switch module,
port A is connected to port 1.
•The [Route B <->] field shows that, within the Optical Switch module,
port B is connected to port 2.
Dependent and Independent Routing
Dependent Routing
If Route A <-> is dependent on Route B <->, editing the number of the port
assigned to Route A <-> automatically updates the number of the port
assigned to Route B <->.
For example, a 81594B 2x2 non-blocking (crossover) switch has two
routes described by [Route A <-> 1] [Route B <-> 2] and
[Route A <-> 2] [Route B <-> 1].
Independent Routing (Only possible for discontoninued 81592A/S switch modules)
If Route A <-> is independent of Route B <->, there are two separate
switched channels. There are two numbered ports that you can assign to
Route A, and two separate numbered ports that you can assign to Route B.
For example, a 81592B dual 1x2 switch allows you to switch Route A <->
to [Route A <-> 1] or [Route A <-> 2], and
Route B <-> to [Route B <-> 1] or [Route B <-> 2].
How to set Route A
To switch the route between port A and another numbered port:
1 Use the Cursor key to highlight [Route A <->], then press Enter.
2 Use the Cursor key to enter the number of the port required.
For all switch modules the signal paths are bi-directional.
