General Safety Instructions
CAUTION
1. The computers that have A800P card installed must comply with
the country’s specific safety regulations.
2. Only service personnel should go to install A800P card.
3. Before installing A800P card, please unplug the power cord and
remove the cover from your PC.
4. For avoiding personal injuries and damages to your machine and
A800P card, make sure bracket of the card is secured to the PC ’s
chassis ground by fastening the card with a screw.
5. Electrical Surges, ESD are very destructive to the equipment. To
avoid it, make sure there is a low impedance discharge path from
your computer to chassis ground.
6. To reduce the risk of damage or injury, please follow all steps or
procedures as instructed.

Chapter 1 Overview
1.1 What is Asterisk
The Definition ofAsterisk is described as follows:
Asterisk is a complete PBX in software. It runs on Linux, BSD, Windows
(emulated) and provides all of the features you would expect from a PBX
and more. Asterisk doesvoice over IP in four protocols, andcan
interoperate with almost all standard-based telephony equipment using
relatively cost-effective hardware. Asterisk provides Voicemail services
with Directory, Call Conferencing, Interactive Voice Response,Call
Queuing. It supports forthree-way calling, caller ID services, ADSI, IAX,
SIP, H323 (as both client and gateway), MGCP (call manager only) and
SCCP/Skinny (voip-info.org).

1.2 What is A800P
OpenVoxA800P delivers great voice quality in the telephony systems.
With interchangeable FXS/FXO modules, it can eliminate the
requirement for separate channel banks or access gateways.
TheA800P contains 8 module banks. Each bank supports one analog
interface. The module banks may be filled with up to 8 FXO or FXS
modules enabling the creation of any combination of ports. Scaling of an
analog card solution is accomplished by simply adding additional cards.
A800P works with Asterisk®, Elastix®, FreeSWITCH™, PBX in a Flash,
trixbox®, Yate™and IPPBX/IVR projects as well as other OpenSource
and proprietary PBX, Switch, IVR, and VoIPgateway applications.
Sample application
When you need 4 PSTNlines and 4 extension sets, for example, 4
FXO-100 modules and 4 FXS-100 modules 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
A800P.
2.1 Powersupply
The board should be powered when install any FXS module; please
connect the power sourcewith A800P board by a 4-pin power source
connector.
2.2 Slot compatibility
A800P is compatible with 32-bit 5.0V PCI slot (slot 2), 64-bit 3.3V PCI
slot (slot 3) or64-bit 5.0V PCIslot (slot 4) while PCI-E slot is fit for
A800E; you should confirm your slot type and insert A800P 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 onits own
clock, therefore precision of the clock is limited; each card will 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
There is so much difference between FXO modules and FXS modules,
they canbe 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. FXO modules correspondtoFXO portand the same with FXS
modules and FXS ports. FXO ports allow A800P connect to PSTNlines
and FXS ports connectto extension sets.

2.5 Hardware setup procedure
Power off your PC, remember unplug the AC power cable
Insert A800P into a 3.3V or 5.0V PCIslot
Put timing cable correctly if necessary, for more details, please refer
to HERE
Please plug PSTN lines into FXO ports and extension telephone lines
into FXS ports before you have detected your PSTN line works well.
Fix the boardby a screw
Power on PC

Caution: If any FXS module is setup, you should make
power on. 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 insert
the PSTN lines into FXO ports.After hard ware setup, it is time to install
software.

Chapter 3 Software Installation and Configuration
A800P supports DAHDI software driver on Linux. To make full use of
A800P, you should download, compile, install and configure DAHDI and
Asterisk.
3.1 Download
DAHDI software packages are available on openvox official website or
Digium. Some patches should be added while the driver source is 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 later two are for unzipping them.

If A800P 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

A800P on DAHDI User Manual

# yum install zlib
# yum install zlib-devel
# 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.

A800P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn

After install the dependencies, please change to the directory
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 the 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

A800P 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 opvxa1200 opermode=CHINA
# dahdi_genconf
After running "modprobedahdi"or "modprobewctdm
opermode=CHINA", there is not any indication
information displayed if loaded normally and successfully.
opvxa1200 is the driver module name of A800P.
"opermode"applies to FXO portand is invalid for FXS port, and you are
allowed to take place of "CHINA"to other mode name which is
