1.2 What is D230P/DE230P
The D230P/DE230P is an upgrade product of the D210P/DE210P. They
support T1, E1, and J1 environments and is selectable on a per-card or
per-port basis. D230P/DE230P is supposed to be the most advanced 2
port T1/E1/J1 asterisk® card with superior quality in the open source
community. The leading innovation ensures users to adjust the interrupts
frequency to reduce the CPU load up to 70% and adjust the interrupt
number to avoid interrupt number sharing or conflict. DE230P offers an
on-board Octasic® DSP-based echo cancellation module. It supports T1,
E1, and J1 environments and is selectable on a per-card or per-port basis.
The Octasic® DSP-based EC module enables users to eliminate echo tails
up to 128ms or 1024 taps across all 64 channels in E1 mode or 48
channels in T1/J1 modes. Further, this module takes advantage of the
Octasic® Voice Quality Enhancement to provide superior sound quality
on all calls. D230P/DE230P supports industry standard telephony and
data protocols, including Primary Rate ISDN (both N. American and
Standard Euro) protocol families for voice, PPP, Cisco, HDLC, and
Frame Relay data modes. Both line-side and trunk-side interfaces are
supported. D230P/DE230P 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,

Chapter 2 Hardware Setup
There are some points that should be paid attention to when setting up
D230P/DE230P.
2.1 Span type setup
Each DIP switch controls one span configuration for E1 or T1.Setting
DIP1 to ON means SPAN1 will be E1.Setting DIP1 to OFF means
SPAN1 will be T1.
2.2 CardID switch setup
If want to install more than one card of D430P/DE430P in a PC, you
should take care of the card ID switch. There are two pieces of rules you
must obey:
The first card must be set to 0, which is a card that will be initialized
(i.e. installing driver) firstly when the system boot up. And the second
should be set to 1, and so on.
At most cases, Linux will initialize PCI devices according to their slot
order. The slot nearest to the CPU will be initialized firstly and the far
end slot will be initialized at last. That is to say, the card which is
nearest to the CPU ID should be set to 0 if there is more than one
D430P/DE430P on your machine.

2.3 Slot compatibility
D230P/DE2230P 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 D230P/DE2230P into any type of PCI slot as
previously described.

2.4 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
D230P/DE230P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
13
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 clock line, for details, please refer to HERE.

Figure 3 Hardware detection
If D230P/DE230P 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
D230P/DE230P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
17
# 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.
D230P/DE230P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
18
Among libpri, DAHDI and Asterisk, let’s install libpri firstly. Please
execute those commands under the directory of /usr/src/ in generally:
# cd libpri-XX
# make
# make install
Then change to the directory of dahdi-linux-complete-XX (XX represents
DAHDI version), then perform 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.
D230P/DE230P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
19
# cd asterisk-1.8.5.0
# ./configure
# make
# 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 wct4xxp
# dahdi_genconf
D230P/DE230P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
20
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
A part of system.conf which is one of the basic channel configuration
files is displayed.

2. Country mode modification
In order to match your country pattern, you need to change parameters
loadzone and defaultzone to your country. For example, your system is in
CHINA, you would like them change to:
loadzone = cn
defaultzone = cn
Some zonedata is available in the file
.. /dahdi-XX/tools/zonedata.c, you can refer to it to match
your country mode. Meanwhile, you also need to modify
another parameter which is in file
/etc/asterisk/indications.conf.
country=cn
A part of file /etc/asterisk/dahdi-channels.conf is showed as below.

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,Playback(cc_welcome)
exten => s,n,Hangup()
[from-internal]
exten => _X.,1,Dial(dahdi/g0/${EXTEN})
exten => _X.,n,Hangup
Figure 8 dial plan
Additional function
Users should run command "cat /proc/interrupts" to check
D230P/DE230P has independent interrupt. If it shares interrupt with other
device, it may cause some problems even cannot work normally. While
D230P/DE230P allows users to modify interrupt pin during firmware
upgrade for avoiding conflict. Or you can see if the EC module is
working as follows:
[root@localhost ~]# dmesg | grep VPM
