NCU Parameters

4.9 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.

Country/Area code for NCU parameters

Use the Hex value to program the country/area code directly into this

address, or use the decimal value to program it using SP2-103-001
