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.
S8700 MC: 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.
S8700 IP: 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
CARR-POW (Carrier Power Supply)
on page 770 (S8700 MC), or RMC-ENV
MO (
S8700 IP). 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.
