returns a PASS result. If the loopback is not established within the 15 seconds,
the test fails.
The status of the Far CSU Loopback test will be available in the hardware error
log via error type 3901. Several distinc t aux values will be used to give the user
information of the status of the test.
The
list measurements ds1 summary command will disp lay the length of time the
test has been running (
Test Duration field) and number of b it errors detected
(
Loopback/Span Test Bit-Error Count field). If the test pattern is b eing passed
through the loopbac k cleanly, the number of bit errors should be very low. The
command will also disp lay the type of loopb ack/span test execu ting (
Tes t field),
the type of pattern generated for the loopbac k/span test (
Pattern field), and
whether the pattern (
i.e. 3-in-24 Pattern ) is synchronized ( Synchronized field).
To terminate the test, enter
t est ds1-loop UUCSS end-loopback/span-test or
the release board command. Using the release board command will restore all
trunks or ports on the TN767E DS1 Interface circuit p ack to the in-service state.

Error
Code Test Result Description/ Recommendation
ABORT Internal system error
1. Retry
t est ds1-loop UUCSS far-csu-loopback-test-begin at 1-minute
intervals a maximum of 5 times.
1005 ABORT Far CSU Loopba ck Test cannot be exec uted in the current c onfiguration. To run
this, the TN767E or later suffix DS1 must be adminis tered for 24-channel
operation. The "Bit Rate" field on the DS1 circuit pack administration form must
be set to "1.544" for 24-channel operation.
1015 ABORT Ports on the DS1 Interface circuit pack have not been busied out to
out-of-service.
1. Enter the busyout board UUCSS command to put all trunks or ports of the
DS1 Interface circuit pack into the out-of-service state.
2. Retry the command.
1039 ABORT The DS1 Interface circuit pack is providing timing for the system. Executing this
test could cause major system disruption.
If the DS1 Interface circuit pack needs to be tested, set the synchronization
reference to another DS1 Interface circuit pack or to the Tone-Clock circuit
pack via the following command sequence:
1. Issue the disable synchronization-switch command.
2. Next, issue the set synchronization UUCSS command.
3. Lastly, issue the enable synchronization-switch command.
