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


  • PCI-Card
  • 4 BRI ports
  • ports can be used as internal or external ports (TE / NT - Mode)
  • programmable gate array on board (FPGA)
  • encryption with zero-delay (optional)
  • switchable 100 Ohm terminations
  • Internal 40V power supply  (optional module: Sirrix.PS40V-A)
  • integrated Sirrix PCM bus
  • Channel-driver for Asterisk PBX software
  • Hardware based echo cancellation with conference bridge



  • 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


  • Comprehensive implementation of the DSS1 ISDN stack
  • Layer 1: Hardware with kernel module

  • NT and TE mode in PtP and PtMP configuration
  • Arbitrary number of Layer 2 und 3 instances
  • ISDN numbers with arbitrary length, with or without direct dialling in (MSN + DDI, ITU-T Q.951.1, Q.951.2, ETSI EN 300 064-1, EN 300 052-1)
  • Display of calling party number (CLIP)
    (ITU-T Q.951.3, ETSI EN 300 092-1)
  • CallerID name can be transmitted by Display Information Element
  • Suppression of display of calling party number (CLIR), from telephone menu
    (ITU-T Q.951.4, ETSI EN 300 093-1)
  • Connected Party Number (COLP)
    (ITU-T Q.951.5, ETSI EN 300 097-1)
  • Call forward (CFU, CFNR, CFB, facility protocol), from telephone menu
    (ITU-T Q.952, ETSI EN 300 207-1)

  • Q.SIG supplementary services: Display of calling and connected party names (CNIP and CONP)


  • 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


  • 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
