Chapter 1 Overview
1.1 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).

1.2 What is B400P/BE400P
OpenVox B400P/BE400P is a PCI 2.2 compliant card which supports 4
BRI S/T interface, and BE400P is B400P with a hardware echo
cancellation module. It takes full advantage of Siemens® technology
based Hardware Echo Cancellation Module to deliver the superior voice
quality over the 4 BRI ports that can be configured for TE or NT mode
individually by jumpers. This port configuration is detected by the driver
automatically.
B400P/BE400P S/T BRI interface card delivers superior voice quality in
the telephony systems with advanced Siemens® technology based
hardware echo canceller. It can provide 8 simultaneous voices calls over 4
ISDN BRI line, turns your legacy ISDN BRI equipments into powerful
Voice over IP devices and provides a soft migration path from ISDN
technology to the new Voice over IP world. B400P/BE400P is designed
for building Open Source systems based on Asterisk such as ISDN PBX
and VoIP gateway.
The B400P/BE400P and drivers comply with fully GPLed for the Linux
kernel bring powerful ISDN BRI connectivity to your Linux machine.
B400P/BE400P works well with Asterisk®, Elastix®, FreeSWITCH™,
PBX in a Flash, trixbox®, Yate™and IPPBX/IVR projects as well as other
Open Source and proprietary PBX, Switch, IVR, and VoIP gateway
applications.

Chapter 2 Hardware Setup
There are some points should be paid attention to when setting up
B400P/BE400P.
2.1 Power supply
The board is powered by PCI slot, but some newest model PCs do not
provide +5V on PCI slots, in such cases, you have to set the jumper to
3.3V.
2.2 Slot compatibility
B400P/BE400P 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-E slot; you
should confirm your slot type firstly and then insert B400P/BE400P into
any type of PCI slot as previously described. Some slots are described
like that.
64-bit 5.0V PCI slot
64-bit 3.3V PCI slot

2.3 Setting Card ID
If want to install more than one card of B400P/BE400P in a PC, you
should take care of the card id switch. The state of ON stands for "1"in
binary, OFF represents "0", and 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 the
decimal number is "0". There two pieces of rules you must obey to set
Card ID:
The ID of the first card must be set to 0, the second should be set to 1,
and so on.
The first Card is a card that will be initialized (i.e. installing driver)
firstly once 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 farthest 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 B400P/BE400P 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).

B400P/BE400P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
11
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).
2.5 Power Feeding Connector
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).
2.6 Power Supply
Power Feeding Input
If one of the eight power feeding connectors is CONNECT (ON), you
should connect a D-type connecter from PC power supply to this jack, the
D-type connecter is used to provide power to CDROM and 3.5”HDD.
Power Supply Selection
Some latest model PCs do not provide +5V on the PCI slots. If you use

B400P/BE400P on DAHDI User Manual

12
this kind of PC, it is need to set the jumper to 3.3V.
PCM IN/PCM OUT
The above point is applied to connect two BRI cards.

Plug the hard disk power supply cable (D style) to power feeding
input jack if need to provide power by external equipments, please
refer jumper setting section for more details.
Plug ISDN lines into RJ-45 interfaces which sets as TE mode and
ISDN phone lines into RJ-45 interface which sets as NT mode
Fix the board by a screw
Plug back the AC power cable, and power on PC
Caution: During the above processes, an ESD wrist strap
is needed. Once power is on, you must not attempt to
install or take down the board. After hardware setup
appropriately, it is time to install software.

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

B400P/BE400P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
18
If there is no kernel-devel source in 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 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 of dahdi-linux-complete-XX (XX represents
DAHDI version), then perform commands one by one to install DAHDI.
# cd /usr/src/dahdi-linux-complete-current
# make
# make install
# make config

B400P/BE400P on DAHDI User Manual
OpenVox Communication Co. LTD. URL: www.openvox.cn
19
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
# 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.
