NCU Parameters
4.7 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); if SP2-103 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.
