Sangoma A104DE 4-Port PCI Express Card

This advanced hardware offers exceptional flexibility and reliability for businesses seeking to enhance their communication infrastructure. Featuring four digital telephony ports, the A104DE supports various protocols, including T1, E1, and J1, ensuring compatibility with diverse network environments.

A104DE Key Features

• Quad port T1/E1/J1 card.
• Dimensions: 2U Form factor: 120mm x 55 mm for use in restricted chassis.
• 32-bit bus master DMA data exchanges across PCI interface at 132Mbytes/sec for minimum host processor intervention.
• Ring buffer DMA handling for minimum host intervention and guaranteed data integrity on high-volume systems.
• Intelligent hardware: Downloadable Field Programmable Gate Array programming with multiple operating modes.
• The A104 is the quad-port version of Sangoma’s range of Advanced, Flexible Telecommunications (AFT) hardware designed for optimum voice and data support over T1, E1 and J1.

The A104 provides full-speed 132 Mbps PCI bus transfer with FPGA and DSP-based processing to unload the host CPU in demanding environments such as soft PBX/IVR voice applications. Compatible with 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. Hence, you never have to worry about hardware compatibility issues.

Optional Modes

The A104 and drivers fully support TDM voice gateways for the Asterisk®, Yate®, and OPAL® PBX/IVR projects and 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, the largest CPU load component in a typical soft PBX system.
• Field upgradeable hardware allows new TDM-related functions to be added as they become available.
• Full channelized mode to act as a major network hub for sub-DS1 remotes. The A104 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.
• Raw bitstream interfaces can support arbitrary non-standard line protocols such as non-byte aligned mono synth or bi-synch.
