Example 2:
This example shows the FEP-4600 requirements for setting up parallel Transmission
Groups. For this example, use the diagram below. Because of the way the FEP-4600
supports PU 4 type connections, if you want to provide multiple connections between the
FEP-4600 and a remote NCP, you will need to set up parallel Transmission Groups on
both the ESCON side and the remote side. Remember that the FEP-4600 does not support
Multilink Transmission Groups. Note that depending upon the desired results, you can
define multiple TGs through the same physical ESCON interface, and you can similarly
define multiple TGs through the same LAN interface interface. This however will
continue to give you single points of failure, so you will probably want to establish the
multiple links through physically different interfaces.

The path tables used by the SA14 NCP and SA10 VTAM should look similar to these:
