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.

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.
