Extended Information

The A104 is the, quad port version of Sangoma's range of Advanced, Flexible Telecommunications (AFT) hardware designed for optimum support of voice and data over T1, E1 and J1.

The A104 provides full speed 132 Mbps PCI bus transfer with FPGA based processing to unload the host CPU in demanding environments such as soft PBX/IVR voice applications. Compatible with both the 3.3v and 5v PCI bus, A104 cards operate in all commercially available motherboards sharing IRQs properly with themselves and all other PCI compatible devices, so you never have to worry about hardware compatibility issues.

Like all the Sangoma AFT Series, the A104 is field upgradeable to take advantage of the hardware and software improvements as they become available.

Operational Modes

Voice modes:
The A104 and drivers fully support TDM voice gateways for the Asterisk� , YateT , OPALT PBX/IVR projects, as well as other Open Source and proprietary PBX/Switch/IVR/VoIP gateway applications.
Supports Robbed Bit Channel Associated Signaling (CAS) and ISDN PRI.
Optimized per channel DMA streams and hardware-level HDLC handling unload the host CPU.
EDACT (patent pending) technology is integrated to drastically reduce the load due to software echo cancellation, which is the largest component of CPU load in a typical soft PBX system.
Field upgradeable hardware allows for new TDM-related functions to be added as they become available.
Data only:
T1/E1 and fractional T1/E1, single channel HDLC per bline. To Replace
Full channelized mode to act as major network hub for sub-DS1 remotes. The A104c can support any configuration of up to 124 remote 64kbps connections carrying Frame Relay, PPP or HDLC data. Timeslots can be concatenated to support remote fractional T1/E1/J1 sites in any combination.

Raw bitstream interfaces can be used to support arbitrary non standard line protocols such as non-byte aligned monosynch or bisynch. /ul

Mixed Voice/Data mode:
Robust combination of router/PBX functions in one server.
WAN data connection is supported by Sangoma�s standard WANPIPE� routing stack , completely independently of TDM voice application for total system reliability.
WANPIPE� supports certified, field tested and reliable Frame Relay, PPP, HDLC and X.25.
