Looparound Test (#161)
This test checks the on-board transmission c apabilities of the NPE, the codec, and the battery feed c hip of the analog port. The test p asses if the signal measured by the tone detec tor is within acceptab le limits.
FAIL The terminal equipment is not connected to the circuit pack. Some terminal
equipment, such as modems, may fail even when connected properly.
1. Remotely test the equipment.
2. If the test fails again, look for RING-GEN errors in the error log. If
present, refer to “RING-GEN”.
3. Check all of the wiring between the station equipment and the switch.
Refer to ‘‘LA85 Port Tester’’ in Chapter 5 for instructions on using the
port tester. Then, run the test again.
4. If the test still fails, the set may be defective. Check the set, and replace
it, if necessary.
5. Some terminal equipment could fail even when it is connected properly.
If this is the case, disable the test using the change station extension
command (enter n into the Test field). Note that this action also
disables Tests 6, 7, 161, and 35 on this port.
PASS The station is connected properly to the switch. This test may also pass if no
terminal equipment is connected and the terminal is located very far from
the switch. User-reported troubles on this port should be investigated b y
using other port tests, by examining station wiring, or by examining the
station.
0NO
BOARD The test could not relate the internal ID to the port (no board). This could be
due to incorrect translations, no board is inserted, an incorrect b oard is
inserted, or an insane board is inserted.
1. Check to ensure that the board translations are correct. Use the list
config command, and resolve any problems.
2. If the board was found to be correctly inserted in step 1, issue the
busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board long command. This should re-estab lish the
linkage between the internal ID and the port. If this is not the case,
check to ensure that there is a valid board inserted.
