Running The Sdlc On Line Test - IBM System/36 Maintenance Information Manual

955 Running the SOLe On line Test
The SDLC on line test verifies correct operation of the communications link between two systems, or between
the system and attached SDLC devices (for example, IBM 5251 Model 12 or IBM 5294 controllers). To run
the SDLC on line test to another system, a similar support program must be started at the remote location.
To run the SDLC on line test to a remote work station, you must use the VARY command. See "329
Summary of Useful SSP Procedures" on page 3-11 to change the selected line to off-line.
1.
Key in SDLCTEST on the SSP command line and press the Enter key.
2. Insert diskette 61, when prompted for a diskette.
3. Select:
a. A line number to be tested.
b. REQUESTOR (to start the SDLC test to another system or device) or RESPONDER (to answer the
SDLC test request from another system).
c. YES to review or change the communications configuration. Always attempt to run the test with the
present configuration before making any changes unless you are attempting to run to a system or
device that the customer was not using. ALTERCOM changes the configuration only for the display
station at which it is run. If configuration is correct and diagnostics run at the system console, but
the customer job fails when it is run from another display station, repeat step 3 at that display
station.
d. The hexadecimal address of the remote system, controller, or device to be tested.
Note: If the network is a point-to-point network, you can use hex FF as the address. If the network
is a multipoint network, you must obtain the correct address from the customer.
4. Select the test to be run.
5. Select the number of times the test should be run. You should run two or more of the first six tests at
least 10 times each.
6. Analyze the results. If the test ends with no errors, the communications link is operating correctly now.
