Chapter 1 Introduction to Programming
PROGRAMMING OVERVIEW
The DCS-816 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 three-digit code (e.g. 100).
These MMC codes 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. For example: use MMC 601 to create a station
group; enter system speed dial numbers in MMC 705; and assign soft keys to individual keysets using MMC
722.
System programming may be done from any LCD 12B or 24B keyset. The first thing you must do is open
system programming. As a security measure, a passcode must be known to do this. Figure 1–1 shows the
keys on a display keyset that have special functions during programming.
This manual describes standard settings. Some MMC codes and default data may be different
from those shown depending on the country selected in MMC 812.
PROGRAMMING LEVELS
There are three levels of programming: technician (or system), customer and station. Technician and
customer levels are under passcode protection while 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. For your convenience, the system displays [xxx PGM MODE] when another keyset is in
programming mode.
Technician (System) level
This level is entered via MMC 800 and requires the technician’s passcode. It allows access to all system
programs, station programs and maintenance programs.
Customer level
This level is entered via MMC 200 and requires the customer passcode. It allows access to station programs
and system programs permitted by the technician in MMC 802. 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 102–121 without using a passcode. Each user can only change
station data for his/her own keyset.
When an LCD 12B or 24B keyset is in programming mode, the display shows instructions, prompts and
choices. Existing data is always displayed before it can be changed. The keystroke sequence for each MMC
is detailed in the following pages.
However, before you begin entering customer data:
