5.2 Test after a Radio Tower Installation with Syn-

chronisation

After all devices are correctly installed, a final test must be exe-

cuted. This final test checks if all devices are installed correctly

and whether a trouble free transmitting and receiving mode is

possible.

•

Switch on the first WIMAN radio modem. Always begin

with the WIMAN determined as synchronization master.

•

Radio test

If the synchronization Master is a WIMAN STAR or a

WIMAN LINE Master, conduct a loop back test from

a properly configured WIMAN ACCESS or LINE

Slave.

It the synchronization Master is a LINE Slave, conduct

a loop back test from its LINE Master.

Check the X.21-interface by connecting the X.21-plug of

the Hybrid cable type-2 to the Router.
