Sirrix PCI4S0 ISDN card
6,200.00 SEK
Inc. VAT

In Stock

Sirrix.PCI4S0 is a PCI-based ISDN interface card. It provides 4 BRI (Basic Rate Interface) ports that can be connected directly to both, the public ISDN network as well as to ISDN end-user devices like telephones and fax machines. Sirrix.PCI4S0 is full ISDN combatible and thus, it can be employed for voice applications as well as for data communications.


  • 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 Acex)
  • LED (D9) for display of FPGA status
  • Freely programmable LED (D11)
  • 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)
  • Conference room for three parties (3PTY) in A-law / µ-Law codec with a data
    delay of only one frame (125 µsec)
  • 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).
