2500 ABORT Internal System Error.
1. Retry the command at 1-minute intervals a maximum of 5
times.
3004 ABORT 1. This error could be caused by the switch setting of the
PDM. Verify that the switch on the PDM is set to the “remote
loop” position. When the remote loop around test is
completed, return the switch to the “off” position.
2. This error could be caused by the Network Control Data
Channel. Look for DATA-CHL errors in the Hardware Error
Log.
3. This error could also result if no data equipment is
connected to the data module. Verify that (a) the data
equipment is properly connected to the data module, (b)
that power is available to the data equipment, and that (c)
the data equipment is powered on.
4. This error could also occur if the baud rate of the data
module is set to 19.2 Kbps since the Network Control circuit
pack used by this test does not support baud rates greater
than 9600 bps. Verify that the baud rate of the data module
is set to 9600 bps or less.
1040 FAIL Data received from remote loop back does not match data sent.
1. Check for faulty wiring.
2. Replace the data module and repeat the test.
3. If the test fails, replace the Digital Line circuit pack
associated with the data module and repeat the test.
1070 FAIL Internal software response.
1. Wait one minute and attempt the test again.
2. If the same error persists after five attempts in one-minute
intervals, escalate the problem.
1072 FAIL Poor response from auxiliary channel.
1. Test the Network Control (Netcon) circuit pack using the
test data-module command.
2. If the test fails, replace the Digital Line circuit pack.
1073 FAIL Internal System Error.
1. Wait one minute and attempt the test again.
2. If the same error persists after five attempts in one-minute
intervals, escalate the problem.
