(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-basedtelephony equipment using
relatively cost-effective hardware. Asterisk provides Voicemail services
with Directory, Call Conferencing, Interactive Voice Response,Call
Queuing. It supports three-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 D430E/DE430E
DE430E is a D430E with an EC module, they are upgrade products ofthe
DE410E. It’s supposed to be the most advanced 4 portT1/E1/J1 Asterisk®
card with superior quality in the opensourcecommunity. The leading
innovation ensures users to adjust the interrupt frequency to reduce the
CPU load up to 70% and adjust the interrupt pin to avoid interrupt
number sharing or conflict. DE430E offers an on-board Octasic®
DSP-basedecho cancellation module. It supportsT1, 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 across all 128 channels in E1 mode or 96 channels
in T1/J1 modes. Furthermore, this module takes advantage of the
Octasic®Voice Quality Enhancement to provide superior sound quality on
all calls. D430E/DE430E 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.
D430E/DE430E 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.

Chapter 2 Hardware Setup
There are some points that should be paid attention to when set up
D430E/DE430E.
2.1 Span type setup
Each DIP switch controls one spanconfiguration for E1 or T1 mode.
Setting DIP1 to ON means SPAN1 will be E1.Setting DIP1 to OFF
means SPAN1 will be T1.
2.2 Card ID switch setup
If want to install more than one card of D430E/DE430E 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 bootup. And the second
should be set to 1, and so forth.
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 CPUID should be set to 0 if there is more than one
D430E/DE430E on your machine.

2.3 Slot compatibility
D430E/DE430E is compatible with PCI-E ×1 (slot 1) and ×2, ×4, ×8, ×16
slot, except PCIslot; you should confirm your slot type and insert
D430E/DE430E into any type of PCI-E 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.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.

D430E/DE430E on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
13
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.

Figure 3 Hardware detection
If D430E/DE430E is not recognized by the system, you have to power off
and take out the card, then try to insert it into another PCI-Eslot.
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

D430E/DE430E 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 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 you could go to next one
directly. Otherwise, the systemwill keep on installing 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.

D430E/DE430E on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn

# 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
