Result Description/ Recommendation
2100 ABORT Could not allocate the necessary system resources to run this test.
2000 ABORT Timed out while waiting for a response from the circuit pack.
2300 ABORT The downlink message necessary to run this test could not be sent.
2301 ABORT The timer could not be set before sending the downlink message necessary to
run this test.
1. Retry the command at 1-minute intervals a maximum of 3 times.
2316 ABORT Fiber link is not administered. Administer the DS1 CONV fiber link via the add
fiber-link command.
2321 ABORT DS1 facility is not busied out. Busyout the DS1 facility via the busyout
ds1-facility command. If there is only one DS1 facility, then busyout the DS1
CONV circuit pack via the busyout board command.
2332 ABORT Test is not allowed to execute at the far end with this system configuration
when there is only one DS1 facility available. Check the green LED at the face
plate of the DS1 CONV circuit pack. The green LED should be on if the loop is
complete.
2500 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 3 times.
FAIL Near-end external loopback failed. A problem exists in the path of the
loopback.
1. If the test is executed as a part of an error analysis, then return back to the
related section.
2. Enter display errors and follow the associated repair procedures for any
on-board DS1C-BD errors.
3. If the loopback point is LB 1, replace connectors and cables between the
DS1 CONV A and the CSU A. If the loopback point is LB 2, replace CSU A.
Also see the repair procedure for error type #1025 (Loss of Frame
Alignment).
4. If the test still fails, replace DS1 CONV A circuit pack.
Any PASS Transmission through the path of the loopback is successful. TN1654 DS1
facilities will display the round trip delay time in milliseconds in the Error Code
field. The round trip delay time is defined as the length of time in milliseconds it
takes for the firmware to receive the test pattern after it has been sent. This
measurement is taken on the last DS1 channel tested.
