Sangoma A500BRMDE Basecard 2 - 24 Port BRI PCIe + HW EC

Technical Specifications
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.
Short 2U compatible mounting clips included for installation in 2U rackmount servers and high quality, tested 2 m 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: 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.

Operating Systems
Linux (all versions, releases and distributions from 1.0 up).

Certification
FCC Part 15 Class A, FCC Part 68, CE, TBR3.

Diagnostic Tools
WANPIPEMON, SNMP, System logs.

Architecture
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™ daughterboardscan be mounted in empty slot positions beside the A500 assembly. These are connected to the A500 by a special backplane bus connector.
