Check the XPI levels of both carriers on both sides of the link by checking the
Modem XPI
field of the Radio
Parameters page in the Web EMS. See
Viewing the Radio Status and Settings
. All four carriers should have
approximately the same XPI value. Do not adjust the XPI at the remote side of the link, as this may cause the
XPI at the local side of the link to deteriorate.
Note
In some cases, the XPI might not exceed the required 25dB minimum due to adverse atmospheric
conditions. If you believe this to be the case, you can leave the configuration at the lower values, but
be sure to monitor the XPI to make sure it subsequently exceeds 25dB. A normal XPI level in clear sky
conditions is between 25 and 30dB.
