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.
