1.5M LIF LINE CODE SETTING
LINE RELATED
SUMMARY:
Set the line code form.  The line code can be set to each unit.  When the code form 
is in AMI as in the North American lines, it is necessary to set the network class to 
the constrained network (P×56 kbps) in order to prevent the appearance in string 
of eight  consecutive 0s (zeroes).
STEP PROCEDURE 
Note:
When setting the AMI code, simultaneously set the network  classification capability (112H 
and 113H) as well as the network classification mode (132H and 133H) to “56 kbps  
(constrained)”.  Also set the CODEC (VL5000) on the terminal side to “56 kbps”

1.5M LIF RAI SETTING
LINE RELATED
SUMMARY:
Set the alarm signal types.  The alarm signal types can be set to each unit.
STEP PROCEDURE 
Note:
When the frame format is “D4 (12MF)”, the RAI  (alarm signal) form in T1 (USA) is different 
from that in NTT (Japan).   Only when connecting to NTT lines with “F12”, set the mode to  
“NTT.”
