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

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.
