armed link. Once the Arm command is sent, the GUI will make other functions available.
Arm
: Sends the arming code (11000b) to the link. The status of the link can be confirmed by looking a the Arm/Lbk LEDs
on any of the line cards in the link. Note that some HTU-Rs configured in NIU/Smartjack mode will loop up with the Arm
command. The test set will notify the user when this is the case.
Query Loop
: When sent from the CO and the HTU-C is in loopback mode, it reports the status of the physical link based
on attenuation and margin characteristics.
Time Out Override
: Disables any automatic (timed) loop down feature in the link, so any loop will stay permanently until it
is manually looped down.
Loopback Query
: Send the loopback query code to identify the first device in loopback mode. Once detected, the test set
will display which device is in loopback mode.
Loop Up
: Sends the appropriate loop code to the selected network element (HTU-C, repeaters, or HTU-R), a confirmation
message will be shown to indicate whether the loop was successful or not. Upon successful completion of a Loop up, a
status message will display "Loop up success" and the user can press
Start Test
to proceed to BERT testing. The soft
LEDs in the test set should all be green and can be used as a confirmation, as the test pattern should be coming back.
Loops down
: Sends the loop down without disarming code. The link will remain armed and ready to receive new
commands. Note that some HTU-Rs configured as NIU/Smartjack will not loop down with this command and the
instrument will notify the user if that is the case.
Disarm
: Sends the disarming code and brings down any loopbacks in the link, including the HTU-R in NIU/Smartjack
mode.
