3-1242UDS1-BD (UDS1 Interface Circuit Pack)
3
The Far CSU Loopback Test has the TN464F UDS1 Interface circuit pack transmit
a loopback activation code to the remote CSU, waits up to 15 seconds for return
of the code to verify the loopback has been established, transmits a framed
3-in-24 test pattern, begins counting bit errors in the received test pattern, and
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 type of Loopback/Span test (
Pattern field),
and whether the pattern (
i.e. 3-in-24 Pattern ) is synchronized ( Synchronized
field).
To terminate the test, enter the
test ds1-loop UUCSS end-loopback/span-test
command or the
release board
command. Using the
release board
command
will restore all trunks or ports on the TN464F UDS1 Interface circuit pack to the
in-service state.

Result Description/ Recommendation
ABORT Internal system error
1. Retry the
test ds1-loop UUCSS far-csu-loopback-test-begin command 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 TN464F or later suffix UDS1 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 UDS1 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 UDS1 Interface circuit pack into the out-of-service state.
2. Retry the command.
