Sangoma A104 Digital card

Four-Span T1/E1/J1

Four spans of optimized voice and data over T1, E1, and J1 available with Telco-grade hardware echo cancellation.

Part of Sangoma’s award-winning Advanced Flexible Telecommunications product line, the A104 uses the same high-performance PCI or PCI Express interface that is providing superior performance in critical systems all over the world.

The A104 supports up to 120 voice calls or 8.192 Mbps of full–duplex data throughput over four T1, E1, or J1 lines.

Take advantage of hardware and software improvements, as soon as they become available — like all cards in Sangoma’s AFT family, the A104 is field upgradable with crash-proof firmware.

Choose the Sangoma A104D and A104DE, equiped with world class DSP hardware to achieve carrier-grade Echo Cancellation and Voice Quality Enhancement functions for your telephone systems.

Four T1/E1 spans with a single PCI or PCI-Express interface optimized for high performance voice and data applications
Support for Asterisk®, FreeSWITCH®, and Yate® as well as other Open Source and proprietary PBX, Switch,IVR, and VoIP gateway applications
4-Year warranty

مشخصات فنی

Four T1/E1 spans 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 spans, so both T1 and E1 are supported simultaneously
Support for Asterisk®, FreeSWITCH®, and Yate as well as other Open Source and proprietary PBX, Switch, IVR, and 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 5 V and 3.3 V PCI busses
Line decoding: HDB3, AMI, B8ZS
Framing: CRC-4, Non CRC4, ESF, SF, D4T1/E1. Also compatible with Japan’s J1
A104E and A104DE PCI Express: 1 Lane PCI Express bus
Maximum operational power for PCI: 5 W (1 A @ 5 V) For PCI Express: 4 W (1.2 A @ 3.3 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
Impedance: Configurable to 75ohms or 120ohms
