(emulated) and provides all ofthe features you would expect from a PBX
and more.Asterisk does voice over IP in four protocols,andcan
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 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 D110P/D110E
The D110P/D110E supports E1, T1 and J1 environments. It is selectable
on a per-card or per-portbasis. This feature enables signaling translation
between E1 and T1 equipments and allows inexpensive T1 channel banks
to connect with E1 circuits.
D110P/D110E 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.
D110P/D110E works well with Asterisk®, Elastix®, FreeSWITCH™,
PBX in a Flash, trixbox®, Yate™ and IPPBX/IVR projects as well as
other OpenSourceand proprietary PBX, Switch, IVR, and VoIPgateway
applications.

Chapter 2 Hardware Setup
There are some points that should be paid attention to when setting up
D110P/D110E.
2.1 Span type setup
The jumper P5 on the middle of right side controls the function of each
span at E1 or T1 mode. Setting P5to close means SPAN1 will work at E1
mode. Setting P5 to open means SPAN1 will be T1.
2.2 Slot compatibility
D110P is compatible with 32-bit 5.0V PCI slot, 64-bit 3.3V PCI slot or
64-bit 5.0V PCI slot, but D110E is compatible with PCI-E ×1, ×2, ×4, ×8,
or ×16 slot. You should confirm your slot type and insert D110P into a
PCI slot or put D110E into a PCI-E slot as previously described.
64-bit 5.0V PCI slot
64-bit 3.3V PCI slot
32-bit 5.0V PCI slot
PCI-E ×1 slot

2.3Timing cable
If you have just one card in the system, all channels on that card have
already run under the same clock source, sotiming 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 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
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
D110P/D110E supports DAHDI software driver on Linux. To make full
use of D110P/D110E, 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.
Gain DAHDI source package from OpenVox:

Figure 3 Hardware detection
If D110P/D110E is not recognized by the system, you have to power off
and take out the card, then try to insert it into other PCI or 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
http://ArtTel.ru
D110P/D110E on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn

# 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, youshould 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 youcould 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
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.
http://ArtTel.ru
D110P/D110E on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
15
Please operate thosecommands to install Asterisk.
# cd asterisk-XX
# ./configure
# make
# make install
# make samples
"make samples" will generate 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 wcte11xp
http://ArtTel.ru
D110P/D110E on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn

# 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.
# Span 1: WCT1/0 "Digium Wildcard TE110P T1/E1 Card 0" (MASTER)

2. Country mode modification
In order to match your country pattern, you need to change parameters
loadzone and defaultzone to your country. Forexample, 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, youalso need to modify
another parameter which is in file
/etc/asterisk/indications.conf.
country=cn
Apart offile /etc/asterisk/dahdi-channels.conf is showedas below.
(Modification, if it is not agree with the hardware setup)
; Span 1: WCT1/0 "Digium Wildcard TE110P
T1/E1 Card 0" (MASTER)
group=0,11
context=from-pstn
switchtype = euroisdn
signalling = pri_cpe
channel => 1-15,17-31
context = default
group = 63

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. A part of
outputs are showed in the following figure.
