4.4 NCU PARAMETERS 
The following tables give the RAM addresses  and the parameter calculation units that the 
machine uses for ringing signal  detection and automatic dialing. The factory settings for 
each country are also given. Most of these must be changed by RAM read/write (SP2-
102), but some can be changed using NCU Parameter programming (SP2-103, 104 and 
105); if SP2-103, 104 and 105 can be used, this  will be indicated in the Remarks column.
