CO Demand Diagnostic Test (#3)
For ground start trunks, 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, this test also checks the on-board programmable transmission
circuits that allow the circuit pack to support transmission characteristics of
several different countries.

Result Description / Recommendation
ABORT Could not allocate system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
1000 ABORT System resources required to run this test are not available. The port may be
busy with a valid call.
1. Use the display port UUCSSpp 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 active, then it is unavailable for certain tests. Wait until the port
is idle before retesting.
2. If the port status is idle, retry the command at 1-minute intervals up to 5
times.
1004 ABORT The port was seized by a user for a valid call.
1. Use the display port UUCSSpp 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 active, then it is unavailable for certain tests. Wait until the port
is idle before retesting.
2. If the port status is idle, retry the command at 1-minute intervals up to 5
times.
1005 ABORT Test inapplicable to present configuration. This is a normal condition.
1018 ABORT Test has been disabled via administration.
1. For this test to run, the
Maintenance Tests? field on the trunk group
form must be set to
n. The form is accessed with the change trunk-group
grp# command.
2000 ABORT Response to the test was not received within the allowable time period.
1. Retry the command at 1-minute intervals up to 5 times.
