XXX-BD (Common Port Circuit Pack)
Issue 4 May 2002 10-2015 555-233-123
Neon Test (#220)
This test checks the voltage required to light the neon lamp on an analog terminal.
A relay connects a 150V 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 display port PCSSpp to determine the station
extension. Use status station 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. (Refer to the “Status
Commands” section in
Chapter 8, ‘‘Maintenance Commands and
Trouble-Clearing Aids’’ for a full description of all possible states.)
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 (see errors for RING-GEN).
If it doesn’t occur on port test 48 for ANL-16-L, then all four
ring phases are in use.
