TIE-DS1 (DS1 Tie Trunk)
Conference Circuit Test (#7)
One or more Network Processing Elements (NPEs) reside on each circuit pack
with a TDM-bus interface. (The TN464C/D UDS1 circuit pack has one
SCOTCH-NPE chip instead of several NPE chips). The NPE controls port
connectivity and gain, and provides conferencing functions on a per-port basis.
The Conference Circuit test verifies that the NPE channel for the port being tested
can correctly perform the conferencing function. The NPE is instructed to listen to
several different tones and conference the tones together. The resulting signal is
then measured by a Tone Detector port. If the level of the tone is within a certain
range, the test passes.

Code Result Description / Recommendation
ABORT System resources required for this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
1000 ABORT System resources required to run this test were not available. The port may be
busy with a valid call.
1. Use the display port UUCSSpp command to determine the trunk
2. If the port status is active but the port is idle (no calls), check the error log
3. If the port status is idle, retry the command at 1-minute intervals up to 5
1002 ABORT The system could not allocate time slots for the test. The system may be under
heavy traffic conditions, or it may have time slots out of service due to
TDM-BUS errors. The status health command can be used to determine
whether the system is experiencing heavy traffic.
1. If the system has no TDM-BUS errors and is not handling heavy traffic and
1003 ABORT The system could not allocate a tone receiver for the test. The system may be
oversized for the number of tone detectors present or some of the tone
detectors may be out of service. Issue the list measurements tone-receiver
command to display basic information about the system's tone receivers.
1. Resolve any TTR-LEV errors.
2. Resolve any TONE-PT errors.
3. If neither condition exists, retry the test at 1-minute intervals up to 5 times.

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.
