Port Audit Update Test (#36)
This test sends updates of the CO port translation for all ports on the circuit pack
which have been translated. The update is non-disruptive and guards against
possible corruption of translation data contained on the circuit pack. No
response message is expected from the circuit pack once it receives translation
updates. The port translation data includes: ground or loop start trunk, tone or
rotary dialing trunk, rotary dialing inter-digit timing, network balance R/RC, and
disconnect timing.
7 FAIL 1. Check for errors on TONE-BD or TONE-PT. If there are
errors, take the appropriate actions.
2. If the Reflective Loop Around Test fails for all ports on a
circuit pack, a -5 volt 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 appropriate 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 TYPES OF
POWER UNITS.
NOTE:
To investigate problems with an OLD631DB AC
power source, refer to CARR-POW Maintenance
documentation.
3. Rerun the test.
4. If the test fails again, replace the circuit pack.
PASS CO Trunk Loop Around 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.
