3.2.6 Pre-Operational Testing

The TRXMIM should now be ready for operation. Before placing
the network into service, proceed to Chapter 4, Testing and
Troubleshooting

and test the installation thoroughly to be sure

that all stations are able to be addressed and that data is being
relayed without error. Verify also that the networking software is
configured properly to match the installed network.
