CO Demand Diagnostic Test (#3)

For ground start trunks, port Media Module 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 Media Module should be replaced only if this test fails
with the CO line disconnected.

Description/ Recommendation
Detected tone was not pure dial tone. No action required.
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.
The test could not relate the internal ID to the port.
1
Check to ensure that the board translations are correct.
Translate the board, if necessary.
2
Use the busyout board command.
3
Use the reset board command.
4
Use the release busy board command.
5
Use the test board command. This should re-establish the
linkage between the internal ID and the port.
