The Sangoma A500 S/T BRI Interface Card delivers superior audio quality and scalability. Expand from two to twenty-four BRI interfaces with optional Octasic^™ Telco-grade, hardware echo cancellation.

• From 2 to 24 BRI interfaces (4 to 48 B-Channels) are supported. Mix TE and NT modes, as required. Changing modes requires no jumpers - simply invert the colour-coded module.
• Supports Asterisk^®, Yate^™,   FreeSWITCH^™,   CallWeaver^™, PBX/IVR projects, as well as other Open Source and proprietary PBX, Switch, IVR or VoIP gateway applications.
• Single synchronous PCI and PCI Express interface for all 24 BRI interfaces (48 B-Channels).
• Six BRI interfaces (12 B-Channels) per Remora^™ card.
• Dimensions: 2U Form factor: 187mm x 55mm for use in restricted chassis.
• Short 2U compatible mounting clips included for installation in 2U rackmount servers and high quality, tested 2m 8-pin RJ45 port splitter cables included.
• 32 bit bus master DMA data exchanges across PCI interface at 132 Mbytes/sec for minimum host processor intervention.
• Autosense compatibility with 5 V and 3.3 V PCI busses.
• Fully PCI 2.2 and PCI Express compliant, compatible with all commercially available motherboards, proper sharing of PCI interrupts.
• Intelligent hardware: Downloadable FPGA programming with multiple operating modes. Add new features related to voice and/or data when they become available.
• Power: 800mA peak, operational 300mA max at +3.3 V or 5 V.
• Temperature range: 0 - 50°C.
• Optimized DMA stream and hardware-level HDLC handling unload the host CPU.
• Raw bitstream interfaces can be used to support arbitrary non-standard line protocols, such as non-byte aligned monosynch or bisynch. WANPIPE^® supports certified, field tested, and reliable Frame Relay, PPP, HDLC and X.25.
