Chapter 2 Hardware Setup
There are some points should be paid attention to when setting up B100P.
2.1 Powersupply
The board is powered by PCI slot, but some newest model PCs do not
provide +5Von PCIslots, in such cases, you have to set the jumper to
3.3V.
2.2 Slot compatibility
B100P is compatible with 32-bit 3.3V PCI slot, 32-bit 5.0V PCI slot,
64-bit 3.3V PCI slot or 64-bit 5.0V PCI slot except PCI-Eslot; you
should confirm your slot type firstly and then insert B100P into any type
of PCI slot as previously described.Some slots are described like that.

2.3 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
(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. Softwareinstallation
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

B100P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
16
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 youcould go to next one
directly. Otherwise, the systemwill 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-xx
# make
# make install
# make config

B100P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
17
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-1.8.4.4
# ./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.

B100P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
18
Because once performed, it will cover the old sample configuration files
you have installed.
3.3 Configuration
1. Driverloading
After compiling and installing DAHDI, Libpri and Asterisk, please load
the driver by running commands:
# modprobe dahdi
# modprobe zaphfc (In TEmode)
# dahdi_genconf
# dahdi_cfg -vvv
There are two issues for B100P NT mode:
Sometimes the first call can't work normally, in such cases,it is need
to restart Asterisk.
The systemruns "modprobe zaphfc"in default, but it is for TE
mode, soit is necessary to run "modprobe zaphfc modes=1
force_11_up=0"for NT mode when the machine restarts. After
reboot, please run commands:
# modprobe -r zaphfc

B100P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
19
# modprobe zaphfc modes=1 force_l1_up=0
Or add the following line in the file /etc/modprobe.conf:
options modprobe zaphfc modes=1 force_l1_up=0
After running "modprobe dahdi"or "modprobe zaphfc", there is
not any information displayed if loaded normally and successfully.
"zaphfc"is the driver module name of B100P.
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 that 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 configuration files is
