Sangoma and TDM Voice
For years,
Sangoma has been a trusted supplier of
connectivity hardware and software
products for Wide Area Network (WAN) and
Internet infrastructure for such leading
organizations as Boeing, the Department
of Homeland Defense, IBM, MCI, and the
U.S. military.
Now,
Sangoma has applied its expertise to
voice and data,
through the creation of Sangoma's new
A101, A102, and
A104 AFT (Advanced Flexible
Telecommunication) T1/E/J1 voice/data
cards. All three are tailor-made to work
with
Open
Source PBX ; the free Linux
PBX software that is revolutionizing
telecommunications over TDM (Time
Division Multiplex) networks. |

Less
CPU Demand
Sangoma's
Wanpipe®
drivers take advantage of the AFT technology to
substantially reduce the processing required to
handle TDM voice calls by the host CPU. This
reduces the CPU's workload; resulting in fewer
dropped calls, less jitter, and better voice
quality for callers.
The true
promise of AFT technology lies in our ability to
field upgrade not only the device driver code,
but the card's FPGA firmware as we improve our
TDM voice support. Projects already under way
include hardware level PRI support and true
time-slice channelization on board. These
improvements plus others related to echo and
codec manipulation can be easily retrofitted to
existing AFT hardware as they become available.
Compatible and Flexible
Sangoma's
voice/data cards are designed for compatibility
and flexibility. They are self sensing for 3.3v
and 5v PCI slots and software configurable for
T1/E1 or J1. They share interrupts properly
between themselves and other PCI compatible
devices, supporting unlimited numbers of cards
per PC chassis.
The AFT series
cards all conform to the 2U form factor
specification, both in height and length,
allowing you to install many cards in a 2U
chassis so as to maximize your server capacity.
Rock
solid data modes
In mixed
voice/data installations, the data streams are
separated out in hardware and handled completely
independently of the voice channels by our
standard Wanpipe® data handlers
that have been carrying IP traffic for many
years. Only the voice related traffic gets
diverted to the PBX system.
The result is a
system that is totally reliable, fast and well
managed, while the CPU load is drastically
reduced.
