CO Demand Diagnostic Test (#3)
For ground start trunks only, port circuit pack relays are operated and checks are
made to see if the port can detect and apply ground on the Tip lead. This test also
verifies that there is no external ground on the Ring lead. In the absence of other
failures, the circuit pack should be replaced only if this test fails with the CO line
disconnected.

Test
Result
FAIL Seizure portion of test failed due to hardware problem. Fault is
usually caused by a disconnected trunk.
1. If the CO Demand Diagnostic Test (#3) also failed, display
the Hardware Error Log. If the CO Demand Diagnostic
Test failed because it could not detect ground (indicated
by Error Type 1281 in the Hardware Error Log) AND Error
Type 3329 or 3585 appears in the Hardware Error Log
(with the same last occurred time as Error Type 1281 and
1537), replace the circuit pack.
2. Check trunk wiring to ensure good connection; repeat test
if wiring correction made.
3. Locate another identical CO trunk and swap its wiring with
one under test. Repeat test on both trunks and determine
if problem follows trunk or remains at original port. If
problem follows trunk, refer problem to CO. If problem
remains at port, replace circuit pack and repeat test.
4. If replacing circuit pack does not clear failure, escalate the
problem.
PASS Detected tone was not pure dial tone. [G1, G3iV1.1-286] No
action required.
PASS Trunk was seized, and dial tone was detected. User-reported
troubles on this port should be investigated by using other port
tests and by examining trunk or external wiring.
NO The test could not relate the internal ID to the port (no board).
BOARD
1. Check to ensure that the board translations are correct.
Translate the board, if necessary.
2. Issue the busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board command. This should re-establish
the linkage between the internal ID and the port.
