14.7.2 Automatic X.31-Test
D-Channel
The “X.31 Automatic, D-channel” test consists of two steps:
The ARGUS - Main menu
Select the profile
Start test.
The test can take up to 4 minutes (a
rotating bar will be displayed). The
ARGUS will display the currently tested
TEI, the previously tested TEI and the
results:
1. Step:
The ARGUS tests whether it is possible to access the X.25 service via the
D-channel on the S-Bus access under test. The ARGUS checks all of the
TEIs from 0 to 63 one after the other. All the TEIs, which support X.31-
service on Layer 2, will be displayed.
2. 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-dialing memory under X.31 test number (see page 339).
With the entry of the X.25 access number, you can - if you wish - select a
logical channel (LCN) other than the default.
