HLU-231 List 7E September 23, 1998 43
5 Once the test is complete, do one of the following:
• If the system is to loopdown but remain ARMED, send the IR (Intelligent Repeater) LPDN code
(universal loopdown).
• If all the equipment is to be looped down, disarmed and returned to normal operation, send the disarm
code 11100.
Using the codes listed in Table 14 on page 44 , a network tester can activate loopbacks NLOC or NREM or SMJK
(if enabled). A customer tester can activate loopbacks CLOC or CREM. All loopbacks shown in Table 14 can also
be initiated from the HLU-231 front panel MODE and SEL buttons (see “Setting Options through SEL and
MODE” on page 10 ).
The ARMED mode has an automatic time-out of 120 minutes but this timer is reset to 120 for any
of the following events:
•
Loopback terminates (manually or time-out),
• Query
• Alternate query
• Far end activate
• Another ARM command.
Information specific to HiGain doublers is shown in bold in Table 14 .
