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.
• The following addresses describe settings for the standard NCU.
• Change the fourth digit from "5" to "6" (e.g. 680500 to 680600) for the settings for the first
optional G3 interface unit and from "5" to "7" (e.g. 680700) for the settings for the second
optional G3 interface unit.
