A104 Quad T1 / E1 / J1

Sangoma, Schede Digitali, Schede-VoIP admin Settembre 26th. 2007, 12:04am

Caratteristiche tecniche:

Four T1/E1 ports with a single PCI or PCI-Express interface optimized for high performance voice and data applications.
Mix T1 channel banks and E1 networks with full channel synchronization. TDM clocking mode lets network timing to be passed from a network-connected DS0 to any or all of the other ports, so both T1 and E1 are supported simultaneously.
Support for Asterisk®, Yate™, CallWeaver™ and FreeSwitch™ PBX/IVR Projects, as well as other open source and proprietary PBX, Switch, IVR, or VoIP gateway applications.
All of Sangoma’s AFT products use the same base PCI interface card. Fully compatible with all commercially available motherboards—proper PCI-standard interrupt sharing without manual tuning.
Dimensions: 2U Form factor: 120 mm x 55 mm for use in restricted chassis.
Includes high-quality, tested RJ45 cables and short 2U mounting clips for installation in 2U rack-mount servers.
Intelligent hardware: Downloadable FPGA programming with multiple operating modes. Add new features related to voice and/or data when they become available.
Autosense compatibility with 5V and 3.3V PCI busses.
Line decoding: HDB3, AMI, B8ZS.
Framing: CRC-4, Non CRC4, ESF, SF, D4T1/E1. Also compatible with Japan’s J1.
A104-X and A104D-X PCI Express: 1 Lane PCI Express bus.
Power: 800 mA peak, operational 300 mA max at +3.3 V or 5 V.
Temperature range: 0–50 °C.
32-bit bus master DMA data exchanges across PCI interface at 132 Mbytes/sec for minimum host processor intervention.
Ring buffer DMA handling for minimum host intervention and guaranteed data integrity on high volume systems.
Supports Robbed Bit Channel Associated Signaling (CAS) and ISDN PRI.
T1/E1 and fractional T1/E1, multiple channel HDLC per line for mixed data/TDM voice applications.
Optimized per channel DMA streams and hardware-level HDLC handling unload the host CPU.
Uses raw bitstream interfaces to support arbitrary non-standard line protocols, such as non-byte aligned monosynch or bisynch.
WANPIPE® routing stack is completely independent of TDM voice application for total system reliability.
WANPIPE® supports certified, field-tested, and reliable Frame Relay, PPP, HDLC, and X.25.
Optional DSP Hardware Echo Canceller Daughterboard
G.168–2002 echo cancellation in hardware.
1024 taps/128 ms tail per channel on all channel densities.
DTMF decoding and tone recognition.
Voice quality enhancement: Octasic® music protection, acoustic echo control, and adaptive noise reduction.
