12.13 Back Plate Indications
12.13.1 Voice Channel LED is RED (during a Self Test)
During a Self-Test, a RED voice channel LED may appear, and does not indicate a particular prob-
lem.
12.13.2 All Voice Channel LEDs flash RED
This usually indicates that an unsupported signaling option has been selected. Reconfigure the FXS
card to a supported signaling type.
12.14 Other Fault Indications
12.14.1 No Ringing During a Self Test
If no ringing signal is heard at the drop for a particular channel during a Self Test, there may be an
open or broken pair in the voice cable. If no ringing signal is heard on any channel during a self test,
the voice cable may be disconnected. To correct the problem:
T1 Test 1 or 2 LED is RED. If the T1 Test LEDs remain red for more than
16 seconds after a Self Test is initiated, the
Access Bank II - SNMP has failed the Self Test.
To correct the problem:
1 Verify that the Controller card and at least
one voice card are in place.
2 Power down the Access Bank II - SNMP for
60 seconds, power it up again, and repeat the
Self Test.
3 If the Access Bank II - SNMP fails the Self
Test again, replace the Controller card using the
procedure given in the Maintenance section.
T1 Test 1 or 2 LED flashes YELLOW. The Access Bank II - SNMP is in Network
Loopback. If this condition persists, the Access
Bank II - SNMP may not have received a loop
down code to end the network loopback To
clear this condition:
1 Be sure the Network Loopback switch is set
to OFF.
2 Set the Self Test switch to the Self Test ON
position, then back to OFF.
