A104 QUAD T1/E1 AFT card
The A104 is an updated, quad port
version of Sangoma’s range of
Telecommunications (AFT) hardware
designed for optimum support of voice
and data over T1, E1 and J1.
Based on bus mastering PCI
technology supported by a ring-buffer
DMA architecture, the A104 provides
full speed 132 Mbps PCI bus transfer
with minimal real-time processor load. This provides optimal
performance in demanding environments such as soft PBX/IVR voice
The A104 and drivers fully support TDM voice gateways for the Asterisk™
PBX project, as well as other Open Source and proprietary PBX/Switch/IVR
Supports Robbed Bit Channel Associated Signaling (CAS) and ISDN PRI.
Block mode raw bit-stream interface for integration with the Asterisk Open
Source PBX/IVR platform.
Channelized mode supporting individual DMA into voice timeslots plus on-
board HDLC support of PRI channel for soft PBX implementations that can
use these features.
Field upgradeable hardware allows for new TDM-related functions to be
added as they become available.
T1/E1 and fractional T1/E1, single channel HDLC per line.
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.
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
WANPIPE® supports certified, field tested and reliable Frame Relay, P
