PROGRAMMING
NX-828
HYBRID KEY SYSTEM
1. Introduction To Programming
1.1 Programming Overview
The system arrives from the factory with default data. Connect it to trunks, stations and power,
turn the system on and it is fully operational. The only thing left to do is customise the data to
fit the customer's needs. This is called programming the system.
MMC stands for Man Machine Code and each program is assigned a different 2-digit code.
These MMC are used to view, create or change customer data. Programming is simply
deciding what needs to be done and knowing which MMC is used to do it.
System programming may be done from any NX-24E , NX-24B or NX-6B keyset (see 1.3.1),
add-on module (AOM) or any keyset with an LCD (see 1.3.2). The first thing you must do is
open system programming. As a security measure, a passcode is required in order to do this.
1.2 Programming Levels
There are three levels of programming: System, Customer and Station. System and Customer
levels are under passcode protection; station programming does not require a passcode.
To prevent conflicting data from being entered, only one person at a time can enter
programming with the technician or customer passcode. While programming is in progress,
normal system operation is not affected.
SYSTEM LEVEL
This level is entered via MMC 20 and requires the technician-level passcode. It allows access
to all system programs, station programs and maintenance programs.
CUSTOMER LEVEL
This level is entered via MMC 20 and requires the customer-level passcode. It provides
access to station programs and system programs allowed by the technician in MMC 90. When
using the customer passcode to access station programs, data for all stations can be viewed
or changed.
STATION LEVEL
All keysets can access station programs 10-17 without using a passcode. Each user can only
change data for his/her own keyset.
