Universal Monitoring System
Introduction
The Universal Monitoring System (UMS) is
designed to monitor, record, play- back, analyse
and archive of Telephone call , facsimile traffic
and PC.-connections via modern contents obtaining
from analogue Telephone lines or 2 Mb/s PCM3O/El
digital stream (European isdn).
The standard-system is capable of
simultaneously monitoring and recording up to 30
digital channels and unlimited number of analogue
channels. The monitoring, recording, playing back,
analysing and archiving of data is performed under
control of software packages running on desktop
computers with the special equipment. The
recordings and information about them are stored
in RA1D5 HD-matrix under control of file server
and database server. The recordings analysing
software works in MS Windows.
General
Features of the System
- The system has modular architecture (it is
possible easy modification of system
configuration, i.e. adding new analyst/transcription
consoles and new interface devices).
- Security of data (RA1D5 HD-matrix, security
mechanisms of local area network,
client-server architecture).
- The system is capable of continuos operation
for a minimum of thousands of hours.
- The system is capable of retrieving
transcribed flies and displays them in textual
format within a fraction of second after an
operator request.
- The system use standard main voltage
world-wide.
- The system is capable of uninterrupted
operation during power supply variation or
failure of duration not exceeding several
minutes and is capable of automatically
rebooting following power supply variation or
failure of duration exceeding several minutes.
- The system has small weight and dimension (typical
PC-computers).
- Quick and easy repairing (typical
PC-computers).
- Telephone conversations, facsimile data or
PC-links are stored on RA1D5 HD-matrix in
Central Storage Unit and later can be archived
(either recordings or additional Information)
on removable hard disk or optical disks. The
archiving and restoring of data is a unction
of included software.
- Flexible and easy to use specialised
software to searching, playing-back, analysing
and archiving recordings.
The Interface system for monitoring digital
streams consists of:
PCM/El decoding device (PC computer with
specialized hardware and software included).
The Interface for monitoring analogue lines
consists of three types of interface devices:
- Front- End Terminals (FET)
- local devices (Local Wire-Tapping Devices -
LWTD)
- remote devices (Remote Wire - Tapping
Devices - RWTD, RVVTD8)
One Front-End-Terminal is connected to one
Telephone analogue line. It sends analogue signals
from Telephone line to LWFD (RWTD includes this
device). The connection is transparent for
interlocutors.
The LWTD device is connected to up to eight FET
devices. lt has two functions:
- converting analogue signals to its digital
representation and
- storing it in the CSU (it is connected to
LAN and has direct access to the CSU).
The RWTD device is connected to the analogue
Telephone line and hasn't direct access to the
CSU. lt converts analogue signals to its digital
representations, stores it in its Local Storage
Unit (LSU) and sends contents of its LSU to RWTD
Controller by modern over PSTN Telephone lines or
GSM. The RWTD Controller is connected to LAN and
has direct access to CSU. It receives data from
RWTD and stores it in the CSU.
The RVVTD8 devices is connected to up to 8
analogue Telephone lines. lt works like RVVTD
device, but additionally it allows to play-back
recordings and monitor activity of device locally.
lt works under control of Windows NT.
Analyst and
Transcription Consoles
The analyst and transcription consoles is
designed to monitor Telephone calls and facsimile
traffic, play-back of recordings, modify, delete
and archive data, process of facsimile documents
(CCITT form), print facsimile documents and
operator's notes. The specialised software has
friendly user interface (MS Windows).
Main Functions
of Specialised Software
The specialised software included with the
system has five main groups of functions:
- real-time monitoring of Telephone
conversations, facsimile traffic and PC-links,
- playing-back and analysing of recordings
stored by system (user can listen recorded
conversations, process facsimile recordings
and PC-links and attach his own notes to the
recordings),
- manipulating of data stored by system (filtering,
modifying, deleting, archiving, printing
reports etc.),
- processing facsimile recordings (standard
and non standard protocol), previewing and
manipulating of fax pictures (zooming,
rotating, flipping etc.),
- managing of system objects and parameters.
Structure of the System
The structure of system is based on local area
network (Novell NetWare). The picture No. 1
presents the configuration of system.
Central Storage Unit
The Central Storage Unit (CSU) is designed to
control of storing and manipulating data (recordings
and its descriptions). It consists of:
- File Server: (PC-computer with file server
software, RAID 5 matrix)
- Database Server: : (PC-computer with
database server software)
For a small system it is possible to run file
server and database server software in the one PC.
Interface System
The interface system is designed to decode one
2 Mb/s PCM3O/El stream of data into 30 streams of
data and convert analogue signals from Telephone
lines into its digital representation. The
interface System stores the digital representation
of conversations and facsimile traffic (with
additional information such as date and time of
start and stop recording, extension or Telephone
number and user location etc.) in the CSU.
