Reading the Status Messages
If the channel group is working, the Status line displays OK . This status line is updated
every 3 seconds. If there is an error, a message is displayed. The following table lists
the types of error messages and the appropriate actions.
Error Message Meaning Action
HW failure: <No
Answer> Major hardware problem.
Board is not responding to
commands. Reasons could
be: 1) DSP loading failure;
2) If PRI, board failed.
1.
Reset board.
2. If error continues, replace
board.
HW failure: <No
Clocks> No clock signal is detected
on T1 interface drop. 1. Check MVIP clock.
2.
Reset board. If this does not
work, replace board.
L1 failure: <No
Signal (LOS)> Layer 1 failure, physical
layer; LOS = Loss of Analog
Signal Check T1/PRI cable and change
if necessary. If cable is okay, CO
is not sending any signal.
Contact CO.
L1 failure: <Alarm
Indication Signal
(AIS)> Layer 1 failure, CO sends all
1’s to our T1/E1; AIS =
Alarm Indicator Signal; all
ones detected To locate the AIS alarm, have
the carrier check the T1 network
element connected to the T1
interface and trace the problem.
L1 failure: <Remote
Alarm Indication
(RAI)> Layer 1 failure, CO notifies
that the configuration is
wrong; RAI = Remote Alarm
Indicator Correct the settings.
L1 failure: <No Sync
Frames Layer 1 failure, physical
layer; no valid framing is
detected. Possible span mis-configuration
(ESF is selected but the actual
framing is SF, or vice versa).
Check span configuration.
