Neon Test (#220)
This test checks the voltage required to light the neon lamp on an analog terminal.
A relay connects a 120V DC source from the backplane of the circuit pack onto
the voltage bus, and another relay connects a 2K shunt from the bus to ground.
Current in the line is then monitored to determine if the voltage is present.
The neon test runs only for TN746 and TN769 Analog circuit packs. If the circuit
pack is not a TN746 or TN769, the test returns PASS, but there is no testing done
to the circuit pack.

Result Description/ Recommendation
1004 ABORT The port was seized by a valid call during the test. The test has been
aborted. Use the display port PCSSpp command to determine the station
extension. Use the status station command to determine the service state
of the port. If the service state indicates that the port is in use, then the port
is unavailable for certain tests. You must wait until the port is idle before
retesting.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1008 ABORT Could not allocate a ringing circuit. Either all the ringing circuits are in use,
or the ringing generator is defective or is not wired correctly.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2. If the test continues to abort, look for RING-GEN errors in the Error
Log. If an ABORT 1008 occurs for this test on other circuit packs as
well, then the ringing generator may be defective or is not wired
correctly. If it doesn’t occur on port test 48 for ANL-16-L, then all four
ring phases are in use.
