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.
