VCS 3020X

THE VCS 3020X IS A COMBINED VOICE

AND DATA SWITCH. THE FIBRE OPTIC

DUPLICATED BACKBONE WITH A BAND-

WIDTH OF 622MBIT/S DISTRIBUTES BOTH

DIGITAL VOICE AND DATA.

THE VCS 3020X USES THE PROVEN APPLI-

CATION SOFTWARE AND THE LATEST PER-

IPHERAL HARDWARE FOR INTERFACES

AND OPERATOR POSITIONS. THIS EXCITING

DESIGN OFFERS FUTURE-PROVEN SWITCH-

ING TECHNOLOGY COMBINED WITH A

SOUND ARCHITECTURE.

VOICE COMMUNICATION SYSTEMS

DECENTRALISED SWITCHING

The major part of the application software of the VCS 3020X runs fully distributed in the
peripheral devices. The critical switching and routing core software is kept simple. The
fully decentralised call control leads to the unrivalled resilience of the system against
software failures. Audio is switched with Time Division Multiple Access (TDMA). Data is
routed within the core system via dedicated IP-based data links.

FREQUENTIS HAS CHOSEN AN EVOLU-

TIONARY APPROACH BY INTRODUCING

VCS 3020X RELEASE 4.0 IN 2004,

WHICH ALREADY PREPARED THE

MIGRATION TO IP-ENVIRONMENTS

AND IP-BASED VOICE SWITCHING.

NOW, THIS MIGRATION CONTINUES

BY COMING UP WITH AN IP-GATEWAY

TO CONNECT TO RADIOS USING

AN IP-INFRASTRUCTURE.

DEMANDS – NOW AND

VOICE COMMUNICATION SYSTEMS – THE VCS 3020X OPENS UP A WORLD OF COMMUNICATIONS

ARCHITECTURE

The architecture of the VCS 3020X balances optimal performance and
low risk communications and is based on a legacy of proven systems
unrivalled in safety and reliability.

The VCS 3020X provides integrated voice communications for radio,
telephone and intercom in one unique system with unlimited confer­encing capabilities.

The VCS 3020X provides any operator access to all communication
channels, regardless of the system load at any side and any time.

4

6000 time slots are available due to the interconnection of multiple
VCS 3020X system nodes. Up to eight duplicated switching nodes are
interconnected via a duplicated optical fibre backbone, carrying both
voice and data.

THE FIBRE OPTIC SYSTEM BACKBONE

The VCS 3020X parallel operating core system.

The extensive duplication of critical system compo­nents, such as the parallel operating core system,
limits the fault range to one communication channel.
Peripheral hardware like operator positions and inter­faces are connected to both duplicated nodes A and B.

DUPLICATION – NO SINGLE POINT OF FAILURE
