COMSPHERE 6800 Series Network Management System
2-186 January 1997 6800-A2-GB31-20
Offline Test (ot)
(Disruptive)
Use the ot command to test the primary and secondary data channel circuits on a DATAPHONE
2700 Series Data Service Unit (DSU). The DSU internally transmits a message to itself 100 times
on the primary and secondary channels. If one or more message errors are detected in the
transmission, the DSU fails the test.
This test is similar to the Device Test (det); however, the Offline Test (ot) command tests the
channel service unit (CSU) and the det command does not. If a DSU passes a Device Test (det),
but fails the ot, the problem is in the CSU.
For most commands, NMS enables you to specify the destination for the command’s results and
schedule its execution. If the last page of the input form cannot accommodate the Destination for
results and Schedule execution fields, an additional page is provided. For a complete description
of these fields, refer to Chapter 1, Introduction.
