“Using

system maintenance programs” (page 154)

At the > prompt, type

LD 45

and press the Enter key.

Select the test condition. Enter XCON 0 and press the Enter key
to perform only one loopback test.

Enter one test period shown in XCON H 1-255, M 1-255,
Sþ1-255 and press the Enter key to select continuous loopback
testing for a selected time span, where Hþ1-255 is 1 to 255
hours, M 1-255 is 1 to 255 minutes, and S 1-255 is 1 to 255
seconds.

Example: XCON M 5 specifies the duration of the test to be
5þminutes.
