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 distinct aux values will be used to give the user
information of the status of the test.
The
list measurements ds1 summary
command will display the length of time the
test has been running (
Test Duration
field) and number of bit errors detected
(
Loopback/Span Test Bit-Error Count
field). If the test pattern is being passed
through the loopback cleanly, the number of bit errors should be very low. The
command will also display the type of loopback/span test executing (
Te s t
field),
the type of pattern generated for the loopback/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 pack to the in-service state.

Error
Code
Tes t
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 Loopback Test cannot be executed in the current configuration. To run
this, the TN767E or later suffix DS1 must be administered 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.
