1.2 What is A1200P
A1200P is the industrial first 12 port analog card with 12 interchangeable
FXS/FXO modules design. It can eliminate the requirement for separate
channel banks or access gateways.
The A1200P contains 12 module banks. Each bank supportsoneanalog
interface. The module banks may be filled with up to 12 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.
A1200P 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 6 PSTNlines and 6 extensions, for example, 6 FXO-100
modules and 6 FXS-100 modules should be installed. PSTNlines
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
A1200P.
2.1 Powersupply
The boardshould be powered when any FXS module is installed, please
connect the power sourcewith A1200P board by a specific connector.
2.2 Slot compatibility
A1200P is compatible with 32-bit 5.0V PCI slot, 64-bit 3.3V PCI slot or
64-bit 5.0V PCI slot except PCI-E slot; you should confirm your slot type
and insert A1200P 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 clockis 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 problems.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 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. FXO modules correspondto
FXO interfaces which receive power (battery) and ring signals, and FXS

A1200P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
12
modules correspondto FXS ports which provides power (battery) and
generates ring signals.
2.5 Splitter
A RJ45 interface of A1200P is divided into four RJ11 portsby a specific
splitter as the picture of Appendix B stated. So you should prepare for
some splitters when install A1200P.
2.6 Hardware setup procedure
Power off your PC,remember unplug the AC power cable
Insert A1200P into a 3.3V or 5.0V PCI slot vertically
Put timing cable appropriately if nesessary
Please plug PSTNlines into FXO ports and extension telephone lines
into FXS ports
Fix the board by a screw
Power on PC
After power on, three rows in total 12 LEDs of the board left will be
light which reflect channels’status, one LED corresponds to a
module.

Figure 4 Hardware setup
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.If all modules are installed, the modules
from 1 to 4 access the uppermost portand the rest modules are grouped
bythe same manner, in another word, every four modules correspondtoa
port in hardware then a port is divided into four channels bya splitter.
You have to insert the PSTNlines into FXO ports and extension
telephone lines into FXS ports.After hard ware setup appropriately, it is
time to install software.

2. Softwareinstallation
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
# 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
updateto 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 youcould go to next one

directly. Otherwise, the systemwill keep on installing it.
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 done,
it is time for you to install Asterisk.
Please operate those commands to install Asterisk.
# cd asterisk-1.8.0
# ./configure
# make

A1200P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
19
# make install
# make samples
"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 "modprobedahdi"or"modprobe
opvxa1200 opermode=CHINA", there is not any
information displayed if loaded normally and successfully.
