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.
