Sirrix PCI4S0EC 4-fach S0-PCI-Karte mit HW Echo Cancellation (Rohde&Schwarz Cybersecurity)

Sirrix Hardware-switched ISDN cards are easy to install, provide extensive stability and enable highly-flexible applications. Some features of Sirrix interface cards:

Hardware

• PCI V2.1 Card
  175 mm x 102 mm
  incl. PCI connector + bracket
• Four S0 ports (BRI)
  1 x RJ45 port each
• Programmable gate array
  (FPGA Altera Cyclone II)
• 2 LEDs (DS1 and DS2) for display of FPGA and card status
• 32 KByte SRAM as B-channel buffer for software switching with a depth of 64, 128, 256 or 512 Byte.
• Sirrix.PCM bus for B-channel switching in hardware across multiple cards (bandwidth 12,288 MBit = 192 B-channels)
• Octasic DSP echo cancellation module with conference bridge providing 16 channels
• Retrievable serial number
• Transparent encryption with low delay of B-channels with an arbitrary block cipher in the operation modes OFB, CFB, CTR or with another arbitrary stream cipher (cf. Sirrix.Crypt datasheet).

• S0 ports (BRI)
  Infineon PSB21150 ISAC-X V1.4
• Each S0 port is configurable in NT or TE mode independently.
• 100 Ohms terminating resistors
• S0 power supply (POWER12, POWER34; 40 V power supply Sirrix.PS40V-A at POWER-40V); current-limiter to 0,1 A (4 W) per port onboard (ETSI EN 300 012-1)
• One LED for each S0 port for display of the Layer 1 activation state

ISDN-Stack

Applications

• Software based PBX systems
• Channel banks and TDMoverIP
• ISDN crypto gateways
• VoIP gateway to the public telephone network or VoIP Gateway for internal extensions
• Least Cost Router for VoIP or CbC

Scalability

• Sirrix.PCM-Bus supports up to 8 ISDN-cards per system with automatic system-wide clock synchronisation
• By interlinking multiple systems, a virtually arbitrary amount of extensions can be served.
• The connection to the public net can be achieved by an arbitrary number of BRI- or PRI-ports.

System Requirements

• Arbitrary computer system
• Free 32 Bit PCI 2.1 slot
• Linux with kernel 2.6
