1.2What is A810P/AE810P
A810P/AE810Pis a new generation analog card, and AE810P is an A810P
with an Octasic®Hardware Echo Cancellation Module on board. With the
interchangeable quad-FXS and quad-FXO modules, A810P/AE810P can
eliminate the requirement for separate channel banks or access gateways.
Once the Octasic®DSP module EC2032 is added to the AE810P, please
make sure you are ready to say goodbyeto the poorvoice quality and
echo echo echo in your phonesystem. No one will even get a chance to
hear that anymore! The AE810P with Octasic DSPmodule will support
Telco-grade hardware echo cancellation on all channels, up to the card’s
maximum configuration in 8 ports with no additional CPUload.
They all works with Asterisk®, Elastix®, FreeSWITCH™, PBX in a Flash,
trixbox®, Yate™ and IPPBX/IVR projects as well as other Open Source
and proprietary PBX, Switch, IVR, and VoIPgateway applications.

FXO-400 module and one FXS-400 module should be installed. PSTN
lines correspondtoFXO modules which are red while extension lines
correspondtoFXS modules which are green.

Chapter 2 Hardware Setup
There are some points that should be paid attention to when setting up
A810P/AE810P.
2.1 Powersupply
The boardshould be powered no matter what modules are installed,
please connect the power sourcewith A810P/AE810P board by a 4-pin
power source connector.
2.2 Slot compatibility
A810P/AE810Pis compatible with any kind of standard PCI2.2 or above
with both3.3 V and 5 V slot while PCI-Eslot is not fit for it; you should
confirm your slot type and insertA810P/AE810P into any type of PCIslot
as previously described.

2.3 Timing cable
If you have just one card in the system, all channels onthat card have
already run under the same clock source, so timing cable is unnecessary.
But if there are more than one card,using timing cable has some
advantages. Before using the clock line, each card works on its own
clock, therefore precision of the clock is limited; each cardwill send
/receive voice data at different speeds.Invoice usage, this small issue can
be omitted, but in data communication such as Fax/Modem, it will cause
big problem. Data loss will cause communication broken or fax broken.
Timing cable will force all cards to work at the same clock source, send
data at the same speed,as a result no data will lost.
If you found J914 (input) and J915 (output) interfaces on the card, it
means the card supports clockline, for the details, please refer to HERE.
2.4 FXO and FXS modules
FXO (Foreign exchange Office) is the office end of the line,
and FXS (Foreign exchange Station) is the station end, there is somuch
difference between them. They can be identified by color, the former
ones are red and the latter ones are green. FXO modules use FXS
signaling while FXS modules use FXO signaling. A FXO module
correspondsto four FXO interfaces which receive power (battery) and

A810P/AE810P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
12
ring signals, and a FXSmodule correspondsto four FXS ports which
provides power (battery) and generates ring signals.
2.5 Splitter
A RJ45 interface of A810P/AE810P is divided into four RJ11 ports by a
specific splitter as the picture of Appendix B stated. So you should
prepare for some splitters when install A810P/AE810P.
2.6 Hardware setup procedure
Power off your PC, remember unplug the AC power cable
Insert A810P/AE810P into a PCI slot
Put timing cable correctly if necessary, for more details, please refer
to HERE
Fix the boardby a screw
Please plug PSTN lines into FXO ports and extension telephone lines
into FXS interfaces before you have detected your PSTNline works
well.
Power on PC

Caution: During the above processes,anESD wrist strap
is needed. Once power is on, you must not attempt to
install or take down the board. Do not forget to connect
PSTNlines into analog phones directly to make sure the lines are
available before inserting the PSTNlines into FXO ports.After hard ware
setup, it is time to install software.

Chapter 3 Software Installation and Configuration
A810P/AE810P supports DAHDI software driver on Linux. To make full
use ofA810P/AE810P, you should download, compile, install and
configure DAHDI and Asterisk. Let’s make the specific DAHDI and
Asterisk version for an example to explain how to install software.
3.1 Download
DAHDI software packages are available on OpenVoxofficial website or
Digium. Some patches should be added while the driver sources are from
Digium, therefore, it is recommended that downloading the DAHDI
driver package from OpenVox official website.
Gain DAHDI sourcepackage from OpenVox:
http://downloads.openvox.cn/pub/drivers/dahdi-linux-complete/openvox_
dahdi-linux-complete-current.tar.gz
Get Asterisk software package from Digium official website:
http://downloads.asterisk.org/pub/telephony/asterisk/releases/asterisk-1.8
.0.tar.gz
Execute the following commands under the directory of/usr/src/ in
general, the former two below are used for downloading these two
packages and the two later are for unzipping them.

3.2 Installation
1. Hardware detection
# lspci –vvvv
Check the outcome and confirm your system has recognized
A810P/AE810P. If it has been recognized, "communication controller"
will be displayed in the output information like that:

Figure 5 Hardware detection
If A810P/AE810P is not recognized by the system, you have to power off
and take out the card, then try to insert it into other PCI slot.
2. Software installation
Some dependencies are crucial. If any of them is absent, the software
installation process would not go through successfully. Let’s run "yum
install XX"(XX stands for the dependency’s name) to check the
availability of dependencies.
# yum install bison
# yum install bison-devel
# yum install ncurses
# yum install ncurses-devel
# yum install zlib
# yum install zlib-devel

A810P/AE810P on DAHDI User Manual

# yum install openssl
# yum install openssl-devel
# yum install gnutls-devel
# yum install gcc
# yum install gcc-c++
# yum install libxml2
# yum install libxml2-devel
If there is no kernel-devel sourcein the system, users
should run the following command to install the
kernel-devel to peer current kernel:
# yum install kernel-devel-`uname –r`
While if there is no matched kernel-devel found, you should download
matched RPMpackage to install it, or execute the following command to
update to the latest and stable kernel version:
# yum install kernel kernel-devel
After installed, please rebootyour machine to apply the new kernel and
install the dependencies. If the dependency has been installed, system
indicates that nothing to do which means you could go to next one
directly. Otherwise, the systemwill keep on installing it.
After install the dependencies, please change to the directory

A810P/AE810P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn

dahdi-linux-complete-XX (XX represents DAHDI version), then perform
the following commands one by one to install DAHDI.
# cd /usr/src/dahdi-linux-complete-XX
# make
# make install
# make config
Caution: If there is something wrong after "make",
please refer to HERE. In this url link, the moderator
introduces you a method how to patch. After patching,
save your changes and exit. Then run "make"again, if successfully, you
are going to install Asterisk.
Please operate thosecommands to install Asterisk.
# cd asterisk-1.8.0
# ./configure
# make
# make install
# make samples

A810P/AE810P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
19
"make samples" will install the standard
sample configuration file in the directory/etc/asterisk. As a
freshman, you should perform make samples, that is to say,
it is unnecessary to perform make samples every time. Because once
performed, it will cover the old sample configuration files you have
installed.
3.3 Configuration
1. Driverloading
After compiling and installing DAHDI and Asterisk, please load the
driver by running:
# modprobe dahdi
# modprobe opvxa24xx opermode=CHINA
# dahdi_genconf
After running "modprobedahdi"or "modprobe
opvxa24xx opermode=CHINA", there is not any
indication information displayed if loaded normally and
successfully. "opvxa24xx"is the driver module name of
A810P/AE810P. "opermode"applies to FXO port and is invalid for FXS
port,and you are allowed to take place of "CHINA"to other mode name
