Chapter 1 Overview
The X204 series cards are versatile devices used for connecting your phone
network to the PSTN (Public Switched Telephone Network) world. This is
accomplished through analog connected to the FXO (Foreign Exchange
Office) port, phone handset connected to the FXS (Foreign Exchange
Station) ports, digital lines connected to the BRI (Basic rate ISDN) ports,
and E1(Basic Rate ISDN PRI) ports. The X204 series cards allow Asterisk
to connect to your phone network, creating an office type telephony
environment.

What is Asterisk
The Definition of Asterisk 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 equipments using
relatively cost-effective hardware. Asterisk provides Voicemail services
with Directory, Call Conferencing, Interactive Voice Response, and 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).

Asterisk as a Phone Switch (PBX)
Asterisk can be configured as the core of an IP or hybrid PBX, switching
calls, managing routes, enabling features, and connecting callers with the
outside world over IP, analog (POST), and digital (T1/E1/J1/BRI)
connections.
Asterisk runs on a wide variety of operating systems including Linux,
Mac OS X, OpenBSD, and Sun Solaris. It provides all of the features you
would expect from a PBX including many advanced features that are
often associated with high end (and high cost) proprietary PBXs.
Asterisk’s architecture is designed for maximum flexibility and supports
Voice over IP in many protocols, and can interoperate with almost all
standards-based telephony equipment using relatively inexpensive
hardware.
Asterisk as a Gateway
It can also be built out as the heart of a media gateway, bridging the
legacy PSTN to the expanding world of IP telephony. Asterisk’s modular
architecture allows it to convert between a wide range of communications
protocols and media codecs.

OpenVox Communication Co. LTD. URL: www.openvox.cn
Caution: only connect regulatory equipment (approved
for use in your specific country) to the telecommunications
network voltage circuit port.
Connecting a Timing Cable
The timing port allows up to three X204 series card to share the same
sync (timing) source from the BRI line provider, or provide a consistent
sync source across multiple cards. This is a useful feature foe fax modes
and some voice applications to prevent corruption due to timing slips on
the second and third X204 series cards.
FXO/FXS, BRI and E1 Connection
The X204 series cards provide two RJ11 connectors for access to the
FXO/ FXS and BRI modules installed in the available. Using a standard
RJ45 telephone cable extend to two of the RJ11 connectors associated
with an FXO/FXS module on the X204 series card. Using a standard
RJ45 cable extend to two of the RJ45 connectors associated with a BRI
module on the X204 series card. There is no extension with E1 on the
X204 series card.

If X204 is not recognized by the system, you have to power off and take
out the card to insert it into another PCI slot.
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
# yum install libxml2-devel
X204 hybrid telephony card User Manual
20
OpenVox Communication Co. LTD. URL: www.openvox.cn
If there is no kernel-devel source in the system, users
should run the following command to install the kerneldevel 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.
Change to the directory dahdi-linux-complete-XX (XX represents
DAHDI version), then perform commands one by one to install DAHDI.
# cd /usr/src/dahdi-linux-complete-2.11.1+2.11.1
# make
# make install
# make config
X204 hybrid telephony card User Manual
21
OpenVox Communication Co. LTD. URL: www.openvox.cn
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 Libpri and Asterisk.
Please execute those commands to install Libpri and Asterisk:
# cd ../libpri-1.4.14
# make
# make install
# cd ../asterisk-1.8.22.0
# ./configure
# make
# make install
# make samples
X204 hybrid telephony card User Manual
22
OpenVox Communication Co. LTD. URL: www.openvox.cn
"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.
Driver Configuration
1. Driver loading
After compiling and installing DAHDI and Asterisk, please load the
driver by running:
# modprobe dahdi
#modprobe x200
# modprobe d100m
#modprobe b200m
#modprobe fxs200m
#modprobe fxo200m
# 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
X204 hybrid telephony card User Manual

purchased. Each configuration consists of a number of FXS, FXO, BRI
and/or E1 modules. These modules are identified by their color.
FXS-Foreign Exchange Station (Green Modules)
FXO-Foreign Exchange Office (Red Modules)
BRI- Basic Rate ISDN (Green Modules)
E1-Basic Rate ISDN PRI(Green Modules）
This chapter provides a review of the four module types and their uses
within your Asterisk server.
Note: Only qualified service personnel should be install the card. User
should not attempt to perform this function themselves.
FXS Module
The FXS module allows an X204 series card to initiate and send ringing
voltage to an FXO device such as an analog telephone. Because of the
module design, you can activate additional ports at any time with more
FXS daughter cards.
FXO Module
The FXO module allows an X204 series card to determinate analog
telephone line (POTS). The FXO module passes all the call features any
standard analog telephone line will support. The phone receiving the call
is the last FXO device in the chain. When it receives voltage from an
FXS device, the phone rings. Because of the modular design, you can

activate additional ports at any time with more FXO daughter cards.
BRI Module
You are able to set a port to NT or TE mode, please refer to figure 3 for
visualized information.
If a port works on NT mode, you should set jumper to CONNECT
(ON).
If a port works on TE mode, theoretically it should be set to OPEN
(OFF), but it might connect to some non-standard ISDN terminal
equipments that do not have terminal resistors, for such equipments,
you should set it to CONNECT(ON).
These jumpers control whether supply power to the external ISDN
terminals. You should adjust accordingly as follows:
If the port works on TE mode, you MUST set the jumper to
OPEN(OFF)
There are two aspects when ports work on NT mode. If the ISDN
terminal has the function of power supply, you should set the jumper
to OPEN (OFF); If ISDN terminal isn’t self- powered, you should set
the jumper to CONNECT (ON).

E1 module
The default module is E1 module, if you change to T1 module, when
adding parameters you need to load drivers.
T1 module : modmodprobe d100m t1e1override=0
E1 module : modprobe d100m t1e1override=1

Clock sources
BRI module and E1 module both have a clock source , without
connecting to any clock source interface, just need to change the master
clock and the slave clock in the profile.
/etc/dahdi/system.conf
An example shown as below:
# Span 1: D100M1/0 "OpenVox D100M (E1|T1) Card 0/0"
