Chapter 2 Hardware Setup
There are some points that should be paid attention to when setting up
D210P/DE210P.
2.1 Span type setup
Each DIP switch controls a span configuration for E1 or T1 mode.Setting
DIP1 to ON means SPAN1 will work at E1mode.Setting DIP1 to OFF
means SPAN1 will be T1.
2.2 CardID switch setup
If want to install more than one card of D210P/DE210P 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 CPUwill 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
D210P/DE210P on your machine.

2.3 Slot compatibility
D210P/DE210P is compatible with 32-bit 5.0V PCI slot, 64-bit 3.3V PCI
slot or 64-bit 5.0V PCIslot except PCI-E slots; you should confirm your
slot type and insert D210P/DE210P into any type of PCIslot 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 onits own
clock, therefore precision of the clockis limited; each cardwill 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

D210P/DE210P on DAHDI User Manual

10
big problems.Data loss will cause communication broken or fax broken.
Timing cable will forceall cards to work at the same clocksource, 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 D210P/DE210P 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 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 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.

# cd asterisk-XX
# ./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

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.confwhich 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
Apart of file /etc/asterisk/dahdi-channels.conf is showedas below.
(Modification, if it is not agree with the hardware setup)
; Span 1: TE2/0/1 "T2XXP (PCI) Card 0 Span 1" (MASTER)
group=0,11
context=from-internal
switchtype = euroisdn
signalling = pri_net
channel => 1-15,17-31

After modifying the country mode, please execute the following
command:
# dahdi_cfg –vvvvvv
The command is used for reading and loading parameters in the
configuration file system.confand writing to the hardware. Apart of
outputs are showed in the following figure.
