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 goodbye to the poor voice quality and
echo echo echo in your phone system. No one will even get a chance to
hear that anymore! The AE810P with Octasic DSP module will support
Telco-grade hardware echo cancellation on all channels, up to the card’s
maximum configuration in 8 ports with no additional CPU load.
They all works with Asterisk®, Elastix

Chapter 2 Hardware Setup

There are some points that should be paid attention to when setting up
A810P/AE810P.

2.1 Power supply

The board should be powered no matter what modules are installed,
please connect the power source with A810P/AE810P board by a 4-pin
power source connector.

2.2 Slot compatibility

A810P/AE810Pis compatible with any kind of standard PCI 2.2 or above
with both 3.3 V and 5 V slot while PCI-E slot is not fit for it; you should
confirm your slot type and insertA810P/AE810P into any type of PCI slot
as previously described.

2.3 Timing cable

If you have just one card in the system, all channels on that 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 card will send
/receive voice data at different speeds. In voice 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 clock line, 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 so much
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
corresponds to 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 FXS module corresponds to 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 board by a screw
 Please plug PSTN lines into FXO ports and extension telephone lines

into FXS interfaces before you have detected your PSTN line works
well.

 Power on PC

Caution: During the above processes, an ESD wrist strap

is needed. Once power is on, you must not attempt to

install or take down the board. Do not forget to connect
PSTN lines into analog phones directly to make sure the lines are
available before inserting the PSTN lines 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 of A810P/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 OpenVox official 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 source package 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

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

OpenVox Communication Co. LTD. URL: www.openvox.cn

17

# 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 source in 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 RPM package 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 reboot your 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 system will 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

18

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 those commands 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. Driver loading

After compiling and installing DAHDI and Asterisk, please load the
driver by running:

# modprobe dahdi

# modprobe opvxa24xx opermode=CHINA

# dahdi_genconf

After running "modprobe dahdi" 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

A810P/AE810P on DAHDI User Manual

OpenVox Communication Co. LTD. URL: www.openvox.cn

20

which is available in the file:
../dahdi-linux-XX/linux/drivers/dahdi/fxo_modules.h

If there is any error, please trace the cause. Until all errors are clear up,
you could execute "dahdi_genconf" again, and then go to the next step.
By running "dahdi_genconf", it will generate /etc/dahdi/system.conf and

etc/asterisk/dahdi-channels.conf automatically. Checking whether the
generated files information agrees with your hardware setup, if not, you
should modify to your specific requirements. Do not forget to confirm
dahdi-channels.conf is included in chan_dahdi.conf, if not, run command:

#echo "#include dahdi-channels.conf" >>

/etc/asterisk/chan_dahdi.conf

FXO ports use FXS signaling, while FXS ports adopt FXO signaling. A
part of system.conf which is one of the basic channel configuration files
is displayed.

If Asterisk is already activate, run "asterisk –r" instead. In the CLI,

please run the following command:

localhost*CLI> dahdi show channels

Chan Extension Context Language MOH Interpret
Pseudo default default
1 from-internal default
2 from-internal default
3 from-internal default
4 from-internal default
5 from-pstn default
6 from-pstn default
7 from-pstn default
8 from-pstn default

Figure 9 channels show

If DAHDI channels are found, it means they have been loaded into
Asterisk. You are going to edit dialplan by your requirements.

4. Dialplan edit
Users must make sure that the context "from-pstn" and "from-internal"
are in extensions.conf, here a simple example is given:

# vim /etc/asterisk/extensions.conf

[from-pstn]
exten => s,1,Answer()
exten => s,n,Dial(dahdi/1,,r)
exten => s,n,Hangup()

[from-internal]
exten => 200,1,Dial(dahdi/7/outgoing_number)
exten => 200,2,Hangup()

Figure 10dialplan show

A810P/AE810P on DAHDI User Manual

OpenVox Communication Co. LTD. URL: www.openvox.cn

25

You should write the destination number instead of the

outgoing_number in the above dial plan. The dial plan

achieves that when an extension telephone dials 200,

Asterisk will transfer through channel 7to the destination.
While a call comes from PSTN line, Asterisk answers firstly, and then
gets through to the extension set which connects to channel 1.

After saving your dialplan, please run "asterisk –r", then execute
"reload" in the CLI. Next you are able to make calls.

Additional function

Users should run command "cat /proc/interrupts" to check
A810P/AE810Phas independent interrupt. If A810P/AE810P shares
interrupt with other devices, it may cause some problems even cannot
work normally. While A810P/AE810P allows users to modify interrupt
pin during firmware upgrade for avoiding interrupt conflict.
