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.
0 NO
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 busyout board.
3. Issue reset board.
4. Issue release busy board.
5. Issue test board. 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, the port is unavailable for certain
tests. Wait until the port is idle before retesting.
1. If the port status is idle, retry the command at 1-minute intervals a
maximum of 5 times.
