Co Demand Diagnostic Test (#3) - Avaya G250 Maintenance Manual

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.
This test also checks the on-board programmable transmission circuits that allow the media
module to support transmission characteristics of several different countries.

System resources required to run this test are not available. The port
may be busy with a valid call.
Use the display port GGGVSpp 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.
If the port status is idle, retry the command at 1-minute intervals for a
maximum of 5 times.
The port was seized by a user for a valid call.
