DS1 Board Loopback Test (#1209)
This test is destructive.
The DS1 Board Loopback (BLB) Test causes a loopbac k at the TN767E DS1
board edge and tests DS1 board internal circuitr y.
The test is destructive and c an only be initiated by a system technician
demanded
t est ds1-loop UUCSS ds1/csu-loopback-tests command.
All trunks or ports on the DS1 Interface c ircuit pack must be b usied out via the
system technician busyout board command before running the BLB Test.
When the BLB Test is initiated, maintenance software sends an app ropriate
message to the TN767E DS1 Interface circuit pac k to start the test. The board will
set up the BLB loopbac k, transmit a test pattern, and verify th at the pattern is
received unaltered through the loop back. If the transmitted and received pattern
is different, the test fails.
When the test is complete, all trunks or por ts on the TN767E DS1 Interface circuit
pack are restored to the in-servic e state after the release board command is
entered

Result Description/ Recommendation
ABORT Internal system error
1. Retry
t est ds1-loop UUCSS ds1/csu-loopback-tests at 1-minute intervals
a maximum of 5 times.
1005 ABORT DS1 Board Loopback Test cannot be executed in the current c onfiguration. To
run this Test, the TN767E or later suffix DS1 must be administered for
24-channel operation. The "Bit Rate" fi eld on the DS 1 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 busyout board UUCSS to put all trunks or ports of the DS1 Interface
circuit pack into the out-of-service state.
2. Retry the command.
