ARGUS 152
Automatic X.31 Test
D channel
The “automated X.31 Test in D channel“ consists of two steps:
ARGUS Main Menu.
Select the profile.
Start test
The test can take up to 4 minutes.
The ARGUS will display the currently
tested TEI, the previously tested TEI and
the results:
First step:
The ARGUS tests whether it is possible to access the X.25 service via the
D channel on the ISDN 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 (see
page 364). With the entry of the X.25 access number, you can - if you wish
- select a logical channel (LCN) other than the default.
<Edit>
Change to the profile parameters
(see page 233).
The parameters can be edited.
