Benefits

A unique network interfaces family

Together with the TNA 4600 and CNA 4600 systems, the SNA 4600 forms a unique family of
network interfaces which addresses the variety of needs in network design and throughput, for
single service as well as multiple services architecture.

Self-contained system solution

In one modular compact product, the SNA 4600 offers a comprehensive range of digital video and
data communications services, provides full ATM multiplexing and network single or dual
termination functionality. With the self-contained design of the SNA 4600 system, the Operators
enjoy the benefits of full compatibility between all functions, integrated management and
simplification of configuration and maintenance operations.

Powerful ATM multiplexing

With up to 7 transport stream multiplexing capability within a 3 RU- 19" chassis, the SNA 4600 is
a powerful system, which saves headroom in operational centers (or hubs) for additional
equipment.

Multiple service capability

In addition to its powerful capability MPEG-2 Transport Stream multiplexing, the SNA 4600 offers
through its circuit emulator the capability to mix other digital services in the same telecom network
channel, thus ensuring efficient data transfer and gives the operators the flexibility to adjust the
network communications according to market needs.

Dial-up connection capability (option

The service end-user selects the far-end party and the call parameters by dialling. Connections
are automatically established, performing ATM User-to-Network Interface signalling.

Full Duplex transmission

Thanks to its full duplex transmission capability the CNA 4600 series features universal interfaces
for contribution network interface for MPEG-2 transport whatever the User-to-Network Interface is
(PDH, SDH or leased lines).

ATM Adaptation Layers type 1 and type 5 for real time services

When type 1 Forward Error Correction, Reed Solomon and interleaving can be used to enhance
the residual bit error rate, AAL type 5 can be selected to allow interoperability with AAL type 5 only
based equipment (servers…).

Local or remote control capability

All SNA 4600 components can be controlled and monitored either locally through the menu-driven
illuminated LC Display and front panel keypad which provides monitoring facilities as well as
control of selected parameters.
It can also be remotely managed by the DBS 2930 integrated system manager through an RS 485
bus link which provides a Graphical User Interface for configuration, status and fault monitoring.

DVB, ITU and ATM Forum standards compliant

SNA 4600 strict adherence to DVB and ATM standards ensures interoperability with any other
standard-based equipment.
