4.8 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. The RAM is programmed in hex code unless (BCD) is included in
the Unit column.
