FAIL

The conference capabilities of the port failed (Error Code 7).
The reflective 404-Hz Tone test failed. No transmission was detected to or 

from the port (Error Code 129).
The reflective 1004-Hz Tone test failed. No transmission was detected to or 

from the port (Error Code 131).
The reflective 2804-Hz Tone test failed. No transmission was detected to or 

from the port (Error Code 133).
Fault Isolation: Proceed as follows unless power or tone problems are 
suspected.

1. To make sure the problem is on-board, disconnect the port from the 

CO and retry the test. Coordinate this with the CO, or do it after busy 
hours; otherwise, the CO may put the connection out of service.

2. If the retry fails, replace the circuit pack.

3. If the retry passes and no troubles were reported, disable the test. If 

the retry passes and troubles were reported, refer the problem to the 
CO.

If the Looparound and Conference Circuit tests fail for every port on a circuit 

pack, a -5 Volt power problem is indicated. 

: If a TN736 or TN752 power unit circuit pack is present, either the 

631DB AC power unit or the 676B DC power unit may be defective. (The 

631DB power unit is used in a medium cabinet powered by an AC source. 

The 645B power unit is used in a medium cabinet powered by a DC power 

source.) The system may contain a TN736 or TN752 power unit or a 631DB 

AC power unit, but not both types of power units. 

: If a TN736 or TN752 power unit circuit pack is present, the power 

unit may be defective.
To investigate problems with a 631DB AC or 645B DC power unit, see 

on page 770 (

), or RMC-ENV 

MO (

). If a red LED on TN736 or TN752 power unit circuit pack is 

on, replace the pack.
If the test fails on more than one port:

1. Check for errors on the TONE-BD or the TONE-PT. If there are errors, 

take appropriate actions. 

2. When the tone errors are cleared, rerun the test. 

3. If the test fails again, see Fault Isolation above.
