4.3. NCU PARAMETERS
The following tables give the RAM addresses and units of calculation of the
parameters 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 (Function 06), but some can be
changed using NCU Parameter programming (Function 08); if Function 08
can be used, this will be indicated in the Remarks column. The RAM is pro-
grammed in hex code unless (BCD) is included in the Unit column.
