4-Port BRI card Sirrix.PCI4S0 with Asterisk support available

Sirrix AG security technologies presents 4-port BRI PCI-card with hardware 
switching and optional encryption. This card provides four S0-ports which 
can be connected to the public network (TE mode) or to any ISDN user device 
(NT mode). With the open-source software ASTERISK it can be used to build up 
highly scalable PBX systems. Moreover, Sirrix.PCI40 is able to encrypt ISDN 
links in real-time and thus, is a perfect choice for building 
crypto-gateways.

Saarbrücken, January, 3rd 2005. Today, Sirrix AG, Saarbrücken is offering a 
new 4-port ISDN PCI-card. Every port can be configured for be connected to 
the public network (TE-mode) or to any ISDN end-user device like telephones, 
facsimilies and modems (NT-mode). Together with the power supply module 
Sirrix.PS40V-A, Sirrix.PCI4S0 allows the direct power supply of all 
connected ISDN end-user devices by using the PC-internal power supply.
Sirrix.PCI4S0 which employs the Sirrix.PCM-bus provides a full switching of 
speech and data links with no delay even between different cards 
(hardware-switching of B-channels). Sirrix.PCI4S0 provides a comprehensive 
support for the open-source software PBX ASTERISK and integrates the full 
ISDN protocol stack. Thus, this hardware can be used to realize COTS-based, 
large-scalable Private Branch Exchange (PBX), providing much better 
properties than traditional PBX systems. Additional applications are Voice 
over IP (VoIP) Gateways and Least Cost Routers.

A Field Programmable Gate Array (FPGA) includes mechanisms for providing a 
full rate encryption of all channels without any delay. For more information 
on the encryption, contact technology at sirrix.com.

Sirrix.PCI4S0 can be ordered for 499,- EURO (+VAT) directly at Sirrix AG, 
Saarbrücken. More information can be found at the website

Short profile Sirrix AG

Sirrix AG is a spin-off of Saarland University which has been founded in 
2000 by members of the chair for security and cryptography and has branches 
in Saarbrücken and Bochum. Their main fields of activity are protection of 
complex heterogeneous communication infrastructures and the design and 
development of cryptographic protocols and schemes.

The company considers itself on the edge between research and commercial 
application of security systems. Thus, many activities comprise feasibility 
studies and development of complex cryptographic protocols. Various cutting 
edge work has been done on devices for comprehensive ISDN and GSM encryption 
and prototypes of fully anonymous E-Voting and PDA-based, anonymous E-Cash 
systems.

Sirrix researcher have contributed to more than 30 significant scientific 
publications within the last two years, mainly in recognized international 
conferences and journals like Information Hiding, Milcom, Fast Software 
Encryption, Eurocrypt and others.

Major developments and research projects include security of integrated 
networks, cryptographic copyright protection and microkernel-based secure 
operating systems. Sirrix is member of the EU-funded research project and 
Network of excellence "The Future of Identity in the Information Society" 
(FIDIS).
