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 does voice over IP in four protocols,and can
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 D230P/DE230P
The D230P/DE230P is an upgrade productof the D210P/DE210P. They
supportT1,E1, and J1 environments and is selectable on a per-card or
per-portbasis. D230P/DE230P is supposed to be the most advanced 2
portT1/E1/J1 asterisk® card with superior quality in the opensource
community. The leading innovation ensures users to adjust the interrupts
frequency to reduce the CPUload up to 70% and adjust the interrupt
number to avoid interrupt number sharing or conflict. DE230P offers an
on-boardOctasic®DSP-based echocancellation module. It supports T1,
E1, and J1 environments and is selectable on a per-card or per-port basis.
The Octasic®DSP-basedEC module enables users to eliminate echo tails
up to 128ms or 1024 taps acrossall 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 soundquality
on all calls. D230P/DE230P supports industry standard telephony and
data protocols,including Primary Rate ISDN (bothN. American and
Standard Euro) protocolfamilies 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 OpenSource 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 OFFmeans
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 setto 0, which is a card that will be initialized
(i.e. installing driver) firstly when the system bootup. 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 onthat 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 clockis 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 forceall 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.

Chapter 3 Software Installation and Configuration
D230P/DE230P supports DAHDI software driver on Linux. To make full
D230P/DE230P, you should download, compile, install and configure
Libpri, DAHDI and Asterisk.
3.1 Download
DAHDI software packages are available on OpenVoxofficial 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.

# lspci –vvvv
Check the outcome and confirm your system has recognized DE230P. If it

has been recognized, "communication controller"will be displayed in
the output information like that:

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 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 oninstalling it.

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. Driverloading
After compiling and installing DAHDI and Asterisk, please load the
driver by running:
# modprobe dahdi
# modprobe wct4xxp
# dahdi_genconf
