Verify Operation of TDMS/EADAS Data Link
PROCEDURE
1.
After SDLC 3 is restored to service, verify that the link goes ACT on MCC page
113.
Note:
It may take a minute or more for the link to go active.
2.
Activate the collection of the TRFC30 data on the DRM by entering the following
input command on the MCC/STLWS:
ALW:TRFC30,CLCT;
3.
At the MCC enter the OP:CLK command to verify that the DRM clock minute is
the same as the TDMS clock +/- 1 minute. If the DRM's clock is off by more than
1 minute, use the SET:CLK command to get it in sync with the TDMS clock.
4.
Wait at least 30 minutes for the reports to get generated and then verify that
TDMS received the data.
Note:
The next set of steps can be optionally executed to monitor the X.25
protocol exchange between the DRM and the EADAS/TDMS OS.
Warning: In order to monitor the X.25 protocol on the EADAS/TDMS
data link, all of the other synchronous data links on the DRM must be
temporarily removed from service. The following steps must not be
performed if the DRM is being polled for AMA billing data, if the SCANS
link is active, or if the TNM/SCCS data link is required to be active.
5.
Remove all data links from service except the EADAS/TDMS data link by typing
and entering the following input command on the MCC/STLWS for each data link
except the EADAS/TDMS data link:
RMV:SDL=X; (where X= 0 for SCANS, 13 for AMA, etc)
6.
Switch to the Sun
Enter Key on the MCC's numeric keypad.
7.
Enter CARRIAGE RETURN until the "console login:" prompt appears.
8.
Login to the Sun console as root.
9.
Type and enter the following command to activate the X.25 protocol analyzer
built into the DRM:
/opt/SUNWconn/bin/x25trace -i /dev/lapb x25
Response:
Parsed: x25
Time Protocol
10. At this point, any X.25 packets sent between the DRM and the EADAS/TDMS
OS will be displayed on the Sun console.
11.
To exit out of the X.25 protocol analyzer, enter Control c or hit the Delete Key.
12. To go back to the MCC hold down the Control Key and depress the Enter Key on
the MCC's numeric keypad.
