1.2 What is D410E/DE410E

The DE410E is a D410E with an EC module, and they support E1, T1
and J1 environments. It is selectable on a per-card or per-port basis. This
feature enables signaling translation between E1 and T1 equipments and
allows inexpensive T1 channel banks to connect with E1 circuits.
D410E 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.
D410E 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 setting up
D410E/DE410E.

2.1 Span type setup

Each DIP switch controls one span configuration 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 CardID switch setup

If want to install more than one card of D410E/DE410E 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 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 CPU ID should be set to 0 if there is more than one
D410E/DE410E on your machine.

2.3 Slot compatibility

D410E/DE410E is compatible with PCI-E ×1 (slot 1) and ×2, ×4, ×8, ×16
slot, except PCI slot; you should confirm your slot type and insert
D410E/DE410E into any type of PCI-E slot as previously described.

Figure 2 PCI-E and PCI slots

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
big problems. Data loss will cause communication broken or fax broken.

OpenVox Communication Co. LTD. URL: www.openvox.cn

D410E/DE410E on DAHDI User Manual

11

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.

will be displayed in the output information like that:

Figure 3 Hardware detection

If D410E/DE410E is not recognized by the system, you have to power off
and take out the card, then try to insert it into another PCI-E 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

OpenVox Communication Co. LTD. URL: www.openvox.cn

D410E/DE410E on DAHDI User Manual

15

# 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.

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

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.

OpenVox Communication Co. LTD. URL: www.openvox.cn

D410E/DE410E on DAHDI User Manual

17

# 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

OpenVox Communication Co. LTD. URL: www.openvox.cn

D410E/DE410E on DAHDI User Manual

18

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.
