Sangoma A104

Sangoma A104 is a digital voice card with PCI interface for four E1 channels with support for CAS and ISDN PRI signaling systems.

The Sangoma A104 is a four-port version of Sangoma's AFT series of products designed to provide optimal voice and data processing over T1, E1 and J1 channels.

The Sangoma A104 supports up to 120 telephone connections, providing full-duplex data transmission over four T1, E1 or J1 channels at 8192 kbps.

The Sangoma A104 board provides high-speed data transfer at 132 Mbps over the PCI bus using FPGA and DSP processors to reduce the load on the CPU in resource-intensive applications, such as software PBX/IVR. Supporting PCI bus voltages of 3.3 and 5 V, the Sangoma A104 (Sangoma A104D) boards can be installed in any motherboards available on the market, they support correct distribution of interrupt resources with other PCI devices, so you do not need to worry about compatibility issues.

The Sangoma A104D and Sangoma A104DE cards, with Octasic® DSP hardware and certified echo cancellation algorithms, provide telco-grade echo cancellation and improved audio quality in public and private telephone systems.

Like other Sangoma AFT series products, the Sangoma A104 boards are field expandable, allowing you to take advantage of new hardware and software as it becomes available.
Operating modes
Voice modes:

*
Sangoma 104 boards and drivers fully support TDM voice gateways for connection to Asterisk™, YateT, OPALT, and other open and closed PBX/Switch/IVR/VoIP gateway systems.
*
Channel Assisted Signaling (CAS) and ISDN PRI.
*
Per-channel optimization of DMA streams and hardware HDLC processing helps reduce CPU load.
* EDAC™ technology (patent pending) helps significantly reduce CPU load caused by software echo cancellation processing, which is CPU intensive in software-based PBXs.
* On-site expansion of equipment functionality allows you to add new capabilities as they become available.

Data only:

* T1/E1 stream and truncated T1/E1 stream, one HDLC channel per line.
* Full channel mode for operation in DS1 subchannel switching control mode. The A104 board supports configurations of up to 124 64 kbps connections with Frame Relay, PPP or HDLC protocols. Timeslots can be combined to support truncated T1/E1/J1 streams in any combination.
— The binary signal stream can be used directly to support non-standard data line protocols, such as those with mono or bi-sync without bit alignment.

Mixed Voice/Data Mode:

* Reliable combination of router and PBX functions in one server.
* WAN connections are supported by Sangoma's industry-standard WANPIPE® stack, which is completely independent of TDM applications for increased system reliability.
* WANPIPE® supports certified and well-tested protocols: Frame Relay, PPP, HDLC and X.25.
