NCU PARAMETERS

4.3 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.

NOTE: 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.
