Test; Automatic X.31-Test - Intec Argus 3u plus Manual

9 Single Tests
9.4 X.31 Test
The ARGUS will either perform a "Manual X.31 Test" or an
"Automatic X.31 Test":
In the case of an automatic test, the ARGUS will first setup
the D-channel connection and then begin setting up the
X.31 connection. Afterwards, the ARGUS will automatically
clear the connection and display the results.
In the case of a manual test, the ARGUS will setup a D-
channel connection and an X.31 connection. The duration of
this connection is determined by the user (or the opposing
end). For the duration of the connection, the ARGUS will
repeatedly send a predefined data packet. The ARGUS will
count all of the data packets sent and received and will
display (where possible) the contents of the data packets
received.

9.4.1 Automatic X.31-Test

The "X.31 Automatic, D-channel" test consists of two steps:
First step: The ARGUS tests whether it is possible to
access the X.25 service via the D-channel on
the BRI access under test.
The ARGUS sequentially checks all the TEIs
from 0 to 63. All the TEIs with which the X.31
service is possible on Layer 2, will be displayed.
Second step: For each TEI with which X.31 is possible on
Layer 2, a CALL_REQ packet will be sent and
then the ARGUS will wait for an answer.
Beforehand, the ARGUS will request the entry
of the X.25 access number, which will be saved
in speed-dialling memory under X.31 test
number ("Saving Call Numbers" on page 129).
With the entry of the X.25 access number, you
can - if you wish - select a logical channel (LCN)
other than the default.
