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.
For the TN2147 World Class Central Office circuit pack, this test also checks the
on-board programmable transmission circuitry that allows the circuit pack to
support the transmission characteristics of several countries.

BOARD
The test could not relate the internal ID to the port (no 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.

Result Description/ Recommendation
ABORT Could not allocate system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1000 ABORT System resources required to run this test are not available. The port may
be busy with a valid call. Use the display port PCSSpp command to
determine the trunk group/member number of the port. Use the status
trunk 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. If the port status is idle, then retry the command at 1-minute intervals a
maximum of 5 times.
