2. SC, SI AND DB
2.1 Introduction
The System Configuration, System Installation and Delegate Database Remote Interface is
part of the DCN NG software which allows another controlling entity, not being the DCN NG
Control PC, to use the System Configuration, System Installation and Database applications.
2.2 Remote SC, SI and DB functions
System Configuration (SC) is the application that monitors the hardware configuration of the
congress system and the link between hardware items and user information. Typical SC
issues are, e.g. checking the communication status, determining the system mode and
replacing units.
System Installation (SI) is the application that allows for assigning seatnumbers to units to
create a one to one link between a unique user chosen identifier and a congress unit in the
conference hall.
The Database (DB) application allows users to compile a comprehensive database of
information relating to participants at a conference or meeting.
Maintaining the system configuration or performing a system installation with a remote
interface is done by means of calling a defined set of Remote Functions and acting upon a
defined set of Update Notifications. The general concept of remote functions and update
notifications is described in [SRS_INF]. [SRS_INF] also defines the protocol and hardware
conditions concerning the remote interface. This document gives the set of remote functions
and the set of update notifications concerning SC, SI and DB. The relation between remote
function and update notifications is given in the description of each separate remote function.
The system configuration and system installation process however, are also influenced by the
actions of the users performed upon the actual units. Actions such as pressing the
microphone button or disconnecting a unit from the system also results in update notifications
being sent to the remote controller. The relation between unit/user events and update
notifications can be found in the user event matrices in sections 4.1.2 en 6.1.1.
2.2.1 Remote function item explanation
Each description consists of the following items:
• Purpose
A global description of the purpose of the function.
• Availability
CCU System modes in which the function is available. See section 2.3.
• Parameter structure for the function
The input parameters needed to fulfill the function. When the function requires no
parameters, no structure is described here.
• Response structure from the function
The output information returned by the function called. This information is only valid when
the ‘wError’ field of the received response information equals SC_E_NOERROR,
SI_E_NOERROR or DB_E_NOERROR.
• Error codes returned
The error values returned in the ‘wError’ field of the response information. All different
error codes are described in Appendix B.
• Update notifications
The update notifications, which are generated during the execution of the remote function.
When there are no notifications generated, then this part will be omitted.
