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
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

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

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
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
“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

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 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
OpenVox Communication Co. LTD.

URL: www.openvoxtech.com 24

A810P/AE810P on DAHDI User Manual
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.
