FAIL

Fail

1.  Check for errors on TONE-BD or TONE-PT.

2. If the Reflective Looparound test fails for every port on a circuit pack, a 

-5V power problem is indicated. 

 / 

: If a TN736 or TN752 power unit circuit pack is 

present, check the circuit pack for a red LED. If the red LED is on, then 
replace the power unit circuit pack. If neither the TN736 nor the TN752 
Power Unit circuit pack is present, then the OLS631DB AC power unit 
may be defective. The system may contain a TN736 or TN752 power 
unit circuit pack or an OLS631DB AC power unit, but not both. See 
RMC-ENV (

), or CARR-POW (

).

3. Rerun the test.

4. If the test fails again, replace the circuit pack.

PASS

CO Trunk Looparound and Conference test is successful. User-reported 

troubles on this port should be investigated by using other port tests and by 

examining trunk or external wiring.
