Preface
This document is meant as a completion to the user manual of the OPERA™
measurement system. It describes the OPERA™ Control Center Server
Software (OPR-003-CTR-X, OPR-010-CTR-X). Before you start reading this
documentation, you should already be familiar with the OPERA™ system in
general.
The purpose of the OPERA™ Control Center is to schedule test calls and the
evaluation of speech quality parameters between various OPERA™ systems
and to remote control these systems through a TCP/IP connection. It allows
the user to create complex schedules consisting of up to some hundred
commands without having to think about the synchronization and allocation
of the resources. Commands may be automatically repeated and
rescheduled after a certain time, e.g. every Monday.
Although the OPERA™ Control Center was originally designed for the
automated monitoring of telecom networks with OPERA™ systems standing
at all important network nodes, it can be used on a single OPERA™ system
as well. Please note, that with the "Light" version of the OPERA™ Control
Center, the software cannot be used to manage a distributed set of OPERA™
systems. If you want to use the OPERA™ Control Center to control other
systems than the local host, you will need the full version. For more
information about this, please refer to Section 8.3 in this manual.
The use of the OPERA™ Control Center is not limited to telecom
applications, it is also applicable to wide band audio applications.
All interface options and all algorithms available for OPERA™ may be used
in conjunction with the OPERA™ Control Center. Typical applications range
from monitoring telecom networks up to automatically test broadcast
transmission links. The OPERA™ Control Center may also be used for
automating tests in an R&D environment if you do not want to write
commandline scripts, although we would generally recommend the
commandline interface for this purpose since it is significantly more flexible
and gives more detailed results. In any case, all results will be stored in a tab
separated text file which can be viewed by the OPERA™ Control Center
itself, or imported into any spread sheet data base program or network
management system for further analysis.
