All trunks or ports on the UDS1 Interface c ircuit pack must b e busied out via the system technician busyout board command before running the ELB Test.When the ELB Test is initiated, maintenance software sends an appropriate message to the TN464F UDS1 Interface circuit pac k to start the test. The board will set up the ELB loopback, transmit a test p attern, and verify that 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 TN464F UDS1 Interface circuit pack are restored to the in-service state after the release board c ommand is entered.
Table 9-697. TEST #1210 CSU Equipment Loopback Test
Error
Code Test
Result Description/ Recommendation
ABORT Internal system error
1. Retry the
test ds1-loop UUCSS ds1/csu-loopback-tests
command at
1-minute intervals a maximum of 5 times.
1005 ABORT CSU Equipment Loopback Test cannot be executed in the current
configuration. To run this test, the
Near-End CSU Type
field on the DS1circuit
pack administration form must be set to
integrated
and the "Bit Rate" field on
the DS1 circuit pack administration form must be set to "1.544" (24-channel
configuration).
1. Use the change ds1 UUCSS command to set the
Near-End CSU Type
field
on the DS1 circuit pack administration form to
integrated
, and/or change
the "Bit Rate" field to "1.544" if the board is to be used in 24-channel
configuration.
2. Retry the
test ds1-loop UUCSS ds1/csu-loopback-tests
command.
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.
1039 ABORT The UDS1 Interface circuit pack is providing timing for the system. Executing
this test could cause major system disruption.
If the UDS1 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.
