The Sangoma A500 S/T BRI interface card delivers superior audio quality and scalability. Expand from two to twenty-four ports of BRI with optional telco-grade hardware echo cancellation.
A single PCI or PCI Express slot hosts the connection for up to 24 ports and ensures common synchronous clocking for all channels with no signaling issues. The card is 100% software configurable.
Finally, a BRI card that upholds Sangoma's high standards of quality in engineering and untiring product support.
The A500 consists of a Remora™ BRI daughterboard mounted on the AFT PCI card. The Remora™ BRI card has three sockets, each of which can accept an S/T BRI module.
One S/T BRI module has two S/T four wire interfaces, which support TE or NT modes of operation. Changing modes requires no jumpers - simply invert the module.
Up to three additional Remora™ daughterboards can be mounted in empty slot positions beside the A500 assembly. These are connected to the A500 by a special backplane bus connector.
From 2 to 24 ports are supported. Mix TE and NT modes, as required. Changing modes requires no jumpers - simply invert the colour-coded module
Support for Asterisk®, FreeSwitch™, and Yate as well as other Open Source and proprietary PBX, Switch, IVR, and VoIP gateway applications
Single synchronous PCI and PCI Express interface for all 24 BRI interfaces
Six ports per Remora™ card
Dimensions: 2U Form factor: 187 mm x 55 mm for use in restricted chassis; includes high quality, tested 2 m 8-pin RJ45 port splitter cables and short 2U compatible mounting clips for installation in 2U rackmount servers
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: 800 mA peak, operational 300 mA 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
