Sirrix PCI4S0EC 4 BRI S0 Card with HW DSP EC Modul
ArtN°: VOSIRX4S0EC
Basic Rate ISDN interface card with integrated HW echo cancellation
Habituellement expédié sous 1 à 3 jours.
- Description
Sirrix.PCI ISDN is a family of PCI-based ISDN interface cards. They provide either BRI (Basic Rate Interface, S0) ports or PRI E1 (Primary Rate Interface, S2M) ports depending on the model. These ports can be connected either to the public network or internally to PBX systems or other ISDN devices. The cards are fully ISDN compatible thus can be employed for voice applications as well as for communications.
Features
- Physical communications layer according to ITU-T G.702/703/704 and I.430/431
- PCI V2.1 Cards, 3.3V and 5V
- Programmable gate array (FPGA Altera)
- Retrievable serial number
- Transparent encryption with zero delay of B-channels with an arbitrary block cipher in the operation modes OFB, CFB, CTR or with another arbitrary stream cipher
- 4 S0 ports (BRI), Infineon PSB21150 ISAC-X V1.4
- Each S0 port is configurable in NT or TE mode independently.
- 100 Ω terminating resistors (switchable)
- internal S0 power supply possible with optional Sirrix.PS40V-A voltage module; current-limiter to 0,1 A (4W) per port onboard (ETSI EN 300 012-1)
- One LED for each S0 port for display of the Layer 1 activation state
- 2 LEDs for display of FPGA and card status
- 32 KByte SRAM as B-channel buffer for software switching
- Sirrix.PCM bus for B-channel switching in hardware across multiple cards (bandwidth = 192 B-channels)
- additionally Octasic DSP echo cancellation module with conference bridge providing 16 channels
