SOFEWARE SETUP
The following are addresses that need to be set in the MCU 5000A.  Set the 
following addresses to the appropriate values and RESET the MCU when 
complete.
Note 1:
  If the value other than the ones listed above is set, it will not function.
Note 2:

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...

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.”
