5 Reception quality and transmission speeds
For the examination of the receipt quality as well as to error de-
tection, test loops can be generated. The type of test loop can be
influenced by the configuration of the parameters L
oopData
,
L
oopMode
and L
oopTest
.
The parameter
LoopData
enables the setting of the Byte-values
that are to be generated (see page 18). This parameter can be
produced on a WIMAN ACCESS only.
The parameter
LoopTest
enables a switching to a test loop, with
which the data, which can be transmitted, is produced independ-
ently by the WIMAN radio modem (see page 19).
This test loop can already be activated in the lowest authoriza-
tion level and is, in combination with the statistics analysis on
the wireless interface, an outstanding inspection procedure for
radio communication.
The parameter
LoopMode
determines, which bit pattern will be
transferred with the back loop in the loop test operation from the
WIMAN radio modem (see page 18)
Attention:
If the back loop test is execute in an operating radio net, avoid
all values except
normal.
Use of any other value may result in
loss of performance.
5.1 Configuration of a TestLoop with Independently
Generated Data Communication
1. Access the command line level of authorization level one
(see chapter 2 on page 13) and change into the configura-
tion mode. You will see an output similar to:
WIMAN-II (config) >
2. Type in the command
looptest true
.
3. Check with
show looptest
the value for the parameter
Looptest
. This should now be switched to
true
. The fol-
lowing output appears:
WIMAN-II (config) > show looptest
LoopTest false ( true)
The present and the new configuration (in parentheses) of
the parameter are displayed.
