1.2 What is A800E
OpenVox A800E 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.
The A800E 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.
A800E 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 VoIP gateway applications.
Target applications
 Channel Bank Replacement / Alternative
 Small Office Home Office (SOHO) applications
 Small and Medium Business (SMB) applications
 Gateway Termination to analog telephones/lines
Sample application
When you need 4 PSTN lines and 4 extension sets, for example, 4
FXO-100 modules and 4 FXS-100 modules should be installed. PSTN
lines correspond to FXO modules which are red while extension lines

Chapter 2 Hardware Setup
There are some points that should be paid attention to when setting up
A800E.
2.1 Power supply
The board is powered by PCI Express slot, which provides power the
A800E need, so there is no need for external power source no matter what
modules you have setup.
2.2 Slot compatibility
A800E is compatible with any kind of standard PCI-E ×1, ×2, ×4, ×8,
×16 slot while PCI slot is not fit for it; you should confirm your slot type
and insert A800E into any type of PCI-E 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. FXO modules correspond to
FXO interfaces which receive power (battery) and ring signals, and FXS
OpenVox Communication Co. LTD.
URL: www.openvox.cn
11
A800E on DAHDI User Manual
modules correspond to FXS ports which provides power (battery) and
generates ring signals.
2.5 Hardware setup procedure
 Power off your PC, remember unplug the AC power cable
 Insert A800E into a PCI-E 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
 Make your PC power on

A800E on DAHDI User Manual
Caution: If any FXS module is setup, you should make
power on. 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 insert
the PSTN lines into FXO ports. After hard ware setup, it is time to install
software.

If A800E is not recognized by the system, you have to power off and take
out the card, then try to insert it into other PCI-E 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
OpenVox Communication Co. LTD.
URL: www.openvox.cn
16
A800E 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 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.
OpenVox Communication Co. LTD.
URL: www.openvox.cn
17
A800E on DAHDI User Manual
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
OpenVox Communication Co. LTD.
URL: www.openvox.cn
18
A800E on DAHDI User Manual
"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 opvxa1200 opermode=CHINA
# dahdi_genconf
After running "modprobe dahdi" or "modprobe wctdm
opermode=CHINA", there is not any indication
information displayed if loaded normally and successfully.
opvxa1200 is the driver module name of A800E.
"opermode" applies to FXO port and is invalid for FXS port, and you are
allowed to take place of "CHINA" to other mode name which is
OpenVox Communication Co. LTD.
URL: www.openvox.cn
19
A800E on DAHDI User Manual
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.

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 10 dialplan show
OpenVox Communication Co. LTD.
URL: www.openvox.cn
24
A800E on DAHDI User Manual
You should write the destination number instead of the
outgoing_number in the above dial plan. The above dial
plan achieves that when an extension telephone dials 200,
Asterisk will transfer through channel 7 to 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.
