channel while the enhanced motherboard supports 1024 point (128ms).
3)
Uses the DSPs on the motherboard to process echoes, not wasting any host resources.
4)
Not only cancels out the effect of voice playback on DTMF and busy tones detection, but
also avoids self-excited oscillation and howling, minimizes the possibility of registering
wrong DTMF and busy tones in a conference call, especially suitable for VoIP application
environments.

DMA
Uses the DMA technique for data reading and writing, greatly minimizing the cost of host CPU.

Structure
1)
Assembles piecemeal just like piling up building blocks. A motherboard offers 4 channels
and you may use the backboard to extend with up to 7 daughterboards. Then 32
channels are available in total. Although these daughterboards take some space, they
can work without the need of PCI/PCIe slots.
2)
Several kinds of modules are optional for you to install with the mother/daughter boards
to achieve different purposes. Actually, we provide FXS, FXO and FXC (a compound
body of FXS and FXO). FXC has the capability to ensure safe communication even when
the PC is powered off, which eliminates the damage caused by sudden power cuts.
3)
The 2U height and the half-length design (Height: 55mm, Length: 120mm) minimize the
space it needs for installation, allowing a great many choices of mainboards and main
frames.
4) You are allowed to fix the module by bolt and the backboard by ouch onto the
mother/daughter board to prevent them from loosening or disengaging during
transportation or in removal.

Compatibility in Software and Hardware
1)
Compatible with all commercial and home mainboards.
2) Includes PCI 2.2 bus with burst data transmission rate up to 132 MB/s; PNP (plug and
play) feature eliminates the need for jumper leads; general PCI design supports 3.3V/5V
PCI slot and PCI-X slot.
Includes PCI Express 1.0a bus with the single-way transmission rate up to 2.5Gb;
supports PCI Express X1, X2, X4, X8, X16 slots.
3)
Supports Unix, Linux and Solaris.
4) This board driver is compatible with Zaptel. So it supports a lot of open source PBX
systems, like Asterisk, Trixbox, Yate, CallWeaver, FreeSwitch, etc.
