14 Operation on an ISDN Access

ARGUS 145
PLUS
Bit patt. BRI/U
This function is used to select the bit pattern to be sent cyclically
by the ARGUS to perform a BERT on a S-Bus or U interface
access. Several predefined bit patterns are available
Default setting:
2
11
-1
Additionally, it is also possible to enter a 16 bit long pattern of
your choice in binary. Use the horizontal cursor keys to move
the cursor right or left.
<Del.>
Changes the digit before the cursor from 1 to 0
Error level
This is the level used to evaluate whether the BERT had an
"acceptable" bit error rate.
If the BERT has a bit error rate, which exceeds this error level,
the ARGUS will display a "NO" as the test result.
Using the keypad, this parameter can be set to any value from
01 (= 10
-01
) to 99 ( = 10
-99
).
The default threshold (error level) is
10
-06
(1E-06). In the event
that the bit error rate is less than 10
-06
(one error in 10
6
=
1,000,000 sent bits), the bit error rate test will be evaluated as
OK.
HRX value
Setting for the HRX value
(Hypothetical
Reference Connections, see the ITU-T G.821)
Using the keypad, you can enter a value ranging from 0 to
100%.
Default setting:
15%
