Chapter 2 Hardware Setup
There are some points should be paid attention to when setting up
B200E/BE200E.
2.1 Power supply
The board is powered by PCI Express 1.0 or above slot, which provides
+3.3V or 12V on PCI-E slots, so there is no need for external power
source.
2.2 Slot compatibility
B200E/BE200E is compatible with PCI-E ×1, ×2, ×4, ×8 and ×16 slot.
You should confirm your slot type firstly and then insert B200E/BE200E
into the PCI-E slot as previously described. Some slots are described like
that.
64-bit 5.0V PCI slot
64-bit 3.3V PCI slot
32-bit 5.0V PCI slot
PCI-E ×1 slot
32-bit 3.3V PCI slot

2.3 Setting Card ID
If want to install more than one card of B200E/BE200E in a PC, you
should take care of the card ID switch. The state of ON stands for "1" and
OFF represents "0", Card ID is calculated by binary. For instance, the
four switches should be all set to OFF if there is only one card, which
means their corresponding binary value is "0000" and . There two pieces
of rules you must obey to set Card ID:
The ID of the first card must be set to 0, and the second should be set
to 1, and so forth.
The first Card is a card that will be initialized (i.e. installing driver)
firstly when the system boot up. 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 are more than one B200E/BE200E on your machine.
2.4 Adjusting Termination of S/T Interface (100 ohm)
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

B200E/BE200E on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
11
(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).
2.5 Power Feeding Connector
These jumpers control whether supply power for the external ISDN
terminal. Users should adjust accordingly from the following:
If the port works on TE mode, user MUST set the jumper to
OPEN(OFF)
If this port works on NT mode, and the ISDN terminal requires ISDN
power supply, users should set the jumper to CONNECT (ON).
While ISDN terminal does not require ISDN power supply, users
should set the jumper to OPEN (OFF).
2.6 Power Supply
Power Feeding Input
If one of the eight power feeding connectors is CONNECT (ON), users
should connect a D-type connecter from PC power supply to this jack, the
D-type connector is used to provide power to CDROM and 3.5”HDD.
Power Supply Selection
Some latest model PCs do not provide +5V on PCI slots. If use those
kinds of PCs, users have to set the jumper to 3.3V.

If B200E/BE200E is not recognized by the system, you have to power off
and take out the card 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 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 source in the system, you should also
install it by running like:
# yum install kernel-devel
If the dependency has been installed, system will indicate 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 of dahdi-linux-complete-XX (XX represents

DAHDI version), then perform commands one by one to install DAHDI.
# cd /usr/src/dahdi-linux-complete-2.4.1.2+2.4.1
# 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 Libpri and Asterisk.
Please execute those commands to install Libpri and Asterisk:
# cd libpri-1.4.11.5
# make
# make install
# cd asterisk-1.8.5.0
# ./configure
# make

B200E/BE200E on DAHDI User Manual

# 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, Libpri and Asterisk, please load
the driver by running commands:
# modprobe dahdi
# modprobe wcb4xxp
# dahdi_genconf
# dahdi_cfg -vvv
