Sangoma A500 2-24 Port Scalable S/T BRI w/ Echo Cancellation
Sangoma built itsbusiness
by designing hardware that simply works, the first time. We
have taken the time to ensure our BRI solution delivers.
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 Octasic™ 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.
Sangoma A500 -
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™ daughterboards can be mounted in empty
slot positions beside the A500 assembly. These are connected to the
A500 by a special backplane bus connector.
Sangoma A500 - Operating systems
Linux (all versions, releases and distributions from 1.0
up).
Solaris.
Sangoma A500 - Diagnostic tools
WANPIPEMON, SNMP, System logs
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.
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.
Six ports per RemoraTM 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.
